no they`re not the military type but tesco`s are selling large coffee mug ones for £3 each, they`re well made and double lined so you cant burn your lips and perfect for family camping or if you`re like me and prefer a small billy and mug instead of a big mug when you`re on your own, thing is they`ve been highly polished and are outragiously shiny, and i hear tell that matalan are doing them too,i think they`re aimed at the hip and cool people market so they `ve got that wrong for sure " oh yeah, all the forest folk are using them these days , its the in thing " :-D cheers al

I've been keeping half an eye our for a Single skin stainless mug.
So i can put it staight on a fire/ burner and get just that one cup of hot water needed for a brew,. Anyone seen them about?

I've seen a few about by the metal seems thick (like it's going to be lip blisteringly hot when my brew is stone cold). If you don't want to go the military Crusader mug, you could try titanium (mega dough for one of those though!).

Titanium stuff ain't cheap ... and it's also pretty soft stuff (people think that titanium is hard but in fact it is titanium alloys comprising of aluminium, vanadium and tin that are hard).

Hey guys, buy titanium. I just invested in it in the stock market and my stock could use a boost. :-D

Seriously, pay the dough and get some good titanium pots, cup, and spoon. It is great stuff and that's not my broker talking. :) A year from now you'll forget all about how much you paid for them and you will treasure them for their ultralight weight and the fact that you can drink a steaming hot cup of tea without burning your lips.

Of course, I realize that you folks across the pond get screwed on the prices but I can't help that. :-( SnowPeak is excellent!

wow hoodoo you got 2 snowpeak cooking sets ! i only got the track 900 and a spork in titanium. I got a stand, windscreen, halcon stove, folding cup and a bandana inside it. Great stuff indeed, if this 17 years old kid can afford it, than you guys just have to buy it !

been looking to try and find a UK retailer of the SnowPeak trek 700. It's a great looking bit of kit.

http://www.backcountrygear.com/images/snowpeaktrek700tistovecombo.jp g

It's designed to perfectly hold a 100 canister of gas and a mini gas stove, there is a clp on lid with a slot in it, that can be used for draining rice, pasta or whatever.

http://www.snowpeak.co.jp/catalog/spo/gif/2003new/photo/trek700_1.jpg

The slot in the lid also holds a "spork" and another 100 gas canister on top.

http://www.snowpeak.co.jp/catalog/spo/gif/2003new/photo/trek700_4.jpg

It can be used as a pot or a mug and comes with it's own stuff sack. It's also nest-able with other SnowPeak pots in the trek range.

Anyone know where to buy in the UK?

What I would love is a mug that has handles on the side for drinking from, a swing handle that can suspend it over a fire and a lid. Does such a thing exist? Apparantly you used to get something called a "tea can" which seemed to be this sort of thing. When I did a search the only thing that came up was an enamled thing.

I would imagine if you drilled two small holes on tye above trek 700, one hole just above the handle, one hole directly oposite the first, then used either an old wire coat hanger or a bit of snare wire for a removable pot hanger, you'd have exactly what you want.

According to the Field & Trek site the Snowpeak mug has a "Mess storage sac included." Not quite sure what mess they're referring to, but it doesn't sound like something I'd want to store...

Incidentally, I have the larger model of titanium pot, the 900 I think, which has a small frying pan / bowl for a lid. Bit big for a mug but it works and is more practical for cooking than the 700.

Martyn
05-04-2004, 19:06
I think they meant "mesh" Jack. :lol:

http://www.snowpeak.co.jp/catalog/spo/gif/2003new/photo/trek700_3.jpg

Yeah, I know the 700 isn't the best cookpot because of it's size, but I wanted it as a vesatile mug rather than a primary cooking pot. The strainer feature is nice for pasta and rice and it's a good size for brewing up.

MagiKelly
05-04-2004, 21:14
I have thought of drilling holes and using a bit of coathanger but wondered if there was a product that covered both cooking options. In fact I have made this modification to a couple of pots I had that had no pot hangers. Plus the thought of drilling holes in a £25 mug breaks my heart.

I have an MSR TITAN titanium cup kettle

http://www.backcountrygear.com/images/msrtitankettle.jpg

it holds .85lt the handles fold away it has a pouring spout and a nicly fitting lid

its large enough to cook in for one but small enough to be a big mug

I have made a teflon coated hanging arm that clips under the rolled edge to suspend it over a fire

The snow peak ones are better value for money though

You're not getting away that easy. More details if you please and photos if you can. My main questions are what does it look like and where do you get teflon coated wire?

Stuart
06-04-2004, 11:54
The tefoln coated handle was a left over bit from a project to make pot handles for the MOD teflon coated crusader cup

I have no idea where you would get the coating done now

another nice feature is the handle on the lid locks in the upright position so that it does not fall flat whilst cooking

the kettle/cup holds a gas canister and a MSR pocket rocket stove when not in use

i prefure the look of the snowpeak stuff though better value for money and there stoves have pizo igniters

I'll try to put a picture up

I have been looking for proper mug/bowl from a while and have been looked at the crusader type mugs but looking at the trek 700 it seems a far more versitile peice or kit.

Put all do I have still to here back from Snow Peak I am not a aware of a dealer here(not suprising really you can't get a bivvy bag here in Dublin let alone a crusader mug :-( ) so I was wonder if I get one from the net would it hold any other mini stove and gas canister? For example an MSR Rocket Pocket (again I speculating that I will find a retailer for MSR here, but I hope you understand what I am asking) :-?

Personally speaking I still like the metal mug/waterbottle combo.

58 pattern and Crusader works well although I prefer the one qrt canteen and mug which is thineer than the crusader and as such lighter. They boil quicker and are cheap!

Having said that why carry a mug at all if your using a swedish army mess kit?

One characteristic of titanium is that it conducts heat very poorly. Good for aircraft wings, but think about that characteristic when selecting pots to cook (transfer heat to food). Prabably great for keeping hot tea from burning the lips due to same characteristic.

EdS

So guy which one should I go for the MSR titainium kettle or the snow peak. Which pores best?

Which would be best on an open fire?


Actually, what I'm really after is a small tea pot to make green tea in. i was thinking of getting a proper Japanese iron one but there about £40. Its got to be metal as someone in our household,& its not me broke my last pot - and she doesn't even drink green tea (hence wanting a single person one).

So I thought why not get one of the above and kill 2 birds with 1 stone.

For anyone looking for stainless rather than titanium cookware, Seagull brand bowls and stackable, single skin mugs are now being sold under the lifeventure / lifesystems label. Seagul make the stainless steel range sold by MSR. it's strong stuff without being too heavy. Will certainly go on a fire if needed. Look to pay somewhere between 4 and 6 pounds each for a mug or a bowl. A little less than the identical product with the MSR badge.

Oh, and by the way, anyone who'se comfortable buying from the states might find http://www.mickiesplace.com/index.htm worth a look. They stock a good range of MSR and Snow peak, including the titanium stuff. Selling direct and through e-bay. Payment by CC.

I've no connection with them but they've been doing some killer deals on the thermarest ultralight and guidelite mattresses. My first order went fine and I've just placed a second order - two 3/4 length guidelites for not much over £50 delivered.

Have you tried the wee shops in Little Mary Street?
They actually have some good kit, usually have most of the pro-tac stuff in stock for instance, but don't have it on display 'cos of theft.

don't know how it happened, but have a couple of set ups very similar to hoodoo's, great minds eh? :wink: 8-)

what you're looking for is a "mucket" or corn boiler, according to those in the know, it's quite a classic bit of kit stateside.
http://www.richmonville.com/images/3013.h4.gif

as soon as i pluck up enough courage, i'll make a couple of holes in the trek 900 main pot and make a bail with the handle from the frying pan :yikes: then i'll have a high tech version!

a selection of mugs mostly stowed for transport: stainless steel and titanium are better as you can cook in them and then drink out of them. aluminium mugs are just too hot. if the lip of the mug gets heated by flames, just pour a bit of cold water over it and you're ready to drink, no need to muck about with plastic rims or bits of tape on the lip of your mug. that sort of thing is only for "jubby dinlos"
http://outdoors.free.fr/images/sargey_mugs-transport.jpg

left to right: cheapo s/steel thin and light mug, local army surplus shop, £2:50. s/steel measuring jug, £6, tescos. snow peak 600 titanium mug, twenty something, snow and rock. USGI army water bottle and rare mug with "L" handle, small fortune, don't know where you'd get one. 8-) snow peak 900, top bit of kit!

the same mugs: note the snowpeak 600 on home made ultralight multifuel trangia clone 8-)

Cool.... show & tell :wink: :lol:

Just taken delivery (yesterday) of my nice new SnowPeak Trek 700, what a great bit of kit...

http://www.britishblades.com/pics/t7001.jpg http://www.britishblades.com/pics/t7002.jpg

...you get the mesh bag, but you have to supply your own spork, stove and fuel cannisters.

It's designed so it all packs neatly into a single package. Inside the pot goes the stove and another fuel cannister.

http://www.britishblades.com/pics/t7003.jpg

The lid serves to reduce boil times & lifts right off, so you're basically left with a large mug. The slot in the lid is for holding the spork in place during carriage & draining pasta or rice or whatever, and there is a thumb lug for holding the lid on, a sort of a handle - it works very well.

http://www.britishblades.com/pics/t7004.jpg

With a crusader for scale, the capacity is about the same as a crusader...

You can get most of the old thermarests pretty cheap over here at the moment too, I think the guidlite 3/4 is down £40 in store at our place at the mo. Cascade designs (thermarest) have recently changed the whole range of mats they do so old models are going cheap.

i had this idea of making a removable bail for the track 900, using a spring like closure you find on cake shape's and jars. Somehow i can;t seem to find one of those wich are usably..... thats a bit annoying, now i got the track 900 and a staniless billy which are almost the same size...

Anyone tried putting equal volume of water in a Crusader and a Ti mug and heat them on the same stove to see which boils fastest? I have worries about the thermal conductivity on Ti and that overall it will be less efficient.

Can someone put me out of my misery!!!! :shock:

Gary
12-04-2004, 15:00
Not tried it with Titanium mugs but I did try it with a crusader and a US mug - the 1 qrt mug won hands down this I feel is due to the thickness of steel on the crusader.

The titanium mugs I've seen are quiet thin skinned and I would there fore conclude that they would boil much quicker too - with the obvious advantages in fuel and time saved etc.

Ed
12-04-2004, 15:05
The titanium kettles/cups also have the advantage of having lids to keep the heat in and therefore wll boil faster than a standard crusader.

The titanium mugs I've seen are quiet thin skinned and I would there fore conclude that they would boil much quicker too - with the obvious advantages in fuel and time saved etc.

Instinctively, that's what I thought but then I pulled up the data sheet for titanium that shows that it has a thermal conductivity that is ten times less than that of aluminium and about 15 times less than copper. This means that as a rough comparison a mug or pan made of Ti would need much more heat than one of the same thickness made of Al. However, as you say, Ti stuff is a lot thinner, however, I'm still curious as to whether in order to carry a lighter Ti mug or pot you'd have to carry more fuel to heat up the contents with. Add to that my worries about what it's like with weaker heat sources such as a hexy stove ...

An experiment is in order!

SquirrelBoy
12-04-2004, 15:23
Also has anyone noticed how quickly these mugs conduct heat away. I hate it when you`ve gone to all the trouble to make a cuppa and the next minute the things gone cold :roll:

I have a crusader cup and its probably down to the size of it - more surface area to loose heat. Mr Mears mentions somewhere, and have seen him using a crusader with a lid - anyone seen one? - home made design perhaps ??

So that might be a good experiment, set up various mugs of tea and measure how quickly they cool...

Adi007
12-04-2004, 15:25
That's the flipside of high thermal conductivity ... it carries away the heat of your drink quickly.

I wonder if the ideal setup would be a thin copper-bottomed mug with Ti sides :-D

Martyn
12-04-2004, 16:08
Just done my super scientific test just for you Adi... :wink:

Method:

I filled a bowl with about 2L of cold tap water. I used a gas stove with a full 250 cannister and left the valve set at the same throughout - I didn't notice the flame intensity change at all. I lit the stove and let it warm up for 1 minute - all done at kitchen ambient temperature. I used a measuring jug to measure all the water volumes. The Trek 700 has a lid which would improve it's performance, but I thought that gave it an unfair advantage in this test, so I tested it without the lid.

First up was the Trek 700 with 250mls of water from the bowl, it took 2 mins 20 seconds to reach a bouncing boil. I could lift the 700 off the stove with bare hands via it's handle and I was able to take it straight to my lips, it was hot but it didnt burn.

Next, the crusader with 250 mls of water. It took 2mins and 30 seconds to reach a bouncing boil. The handle was very cool, but the body was far too hot to take it straight to my lips.

Next the trek 700 with 500mls of water. It took 4 mins and 20 seconds to reach a bouncing boil, although the handle was very hot, I was still able to remove it from the stove with my bare hands (with care). I poured half the contents away and it was hot, but passed the lip test.

Next, the crusader with 500mls. It took 4 mins and 45 seconds to reach a bouncing boil. The handle was very cool to touch. I poured half away but there was no way in hell I was even going to attempt the lip test.

Summary, the Ti Trek 700 boils faster than the crusader, no question, accross various volumes. The body of the Trek stays cool enough to use it as a drinking mug straight from the stove, no way with the crusader, some cooling of the lip, or some cooling down time is needed. The handle of the trek wasnt brilliant, it got hot (but cooled quickly once off the stove). I was a little twitched about how precarious it was with 500mls of boiling water. Despite it's irregular shape, the crusader was more stable and I could handle it with greater confidence. As a cooking vessel, I would prefer the crusader for it's cool handle, and the weight of it makes it more stable on the stove. As a mug, the Trek is far better, cooler to the lips, a more familiar shape and slighly faster to boil.

For a mug, that you can cook in at a push, the trek wins for me. Stop, take your bergen off, pull out your trek package, add 200-300mls of water, put the lid on, light the stove, wait 2 & 1/2 minutes, add coffee and drink. Couldn't be lighter, simpler, cleaner or faster.

The crusader weighs 250 grams.
The Trek 700 weighs 90 grams (without lid).

This was done with a powerful gas burner with the valve opened wide up. I dont have a meths burner, but would be interested to know the results. If I have a couple of hours to spare one day, I might try it with a hexy stove (edit - I suppose this could be simulated with a gas burner, with the flams set to a super low level). But it should be noted, that the trek 700 is supposed to be a super lightweight, compact gas burner package. It's designed to accomodate 2x100 gas cans inside (or 1 gas can and stove) and a third can on top of the lid - it's not really a hexy solution.

This means that as a rough comparison a mug or pan made of Ti would need much more heat than one of the same thickness made of Al....

That would be for pure Titanium. These mugs are Titanium alloys, with Alu and other metals added. Alloys have very different thermal properties to pure metals.

Adi007
12-04-2004, 17:17
Very interesting Martyn - thanks for that! :biggthump

A lot depends on the Ti alloy used, although many of the alloys I've come across have poor thermal conductivity compared to Al and Cu ... but then again a gas burner puts out a lot energy. The bottom line must come down to the fact that they can make a thinner mug with Ti.

I wonder, do you have a black crusader mug of brushed metal as that would make a difference too.

Martyn
12-04-2004, 17:31

No, don't worry about it. :-D I've got some Ti spoons so I might have a play later to see how fas the handles heat up when the ends are in boiling water.

I've got both types of mug and I've noticed that the black one cools quicker (because it emits better) than the brushed one ... equally it should warm up quicker.

12-04-2004, 17:41
the relatively poor conductivity of the Ti and s/steel is what makes 'em usable as cooking and drinking mugs, as martyn's tests show.

this lack of conductivity becomes a real problem when you're trying to cook foods with less water content, try simmering a pot of porridge for example. you'll find that even with a nice gentle simmer on top you'll have a good chance of burnt food in the bottom of the pot. i reckon your best lightweight bet would be to have a Ti mug, with hard anodised ally everything else. if you're not so worried about keeping the weight down, youcn get copper bottomed s/steel cooksets, i don't know if they're really significantly better. thicker kitchen pans spread the heat muchmore evenly than backpacking pots.

martyn, hexy blocks provide the lightest of all fuels. also the most expensive. what you really need is the multifuel trangia clone shown ready to go in my last pic.

Martyn
12-04-2004, 18:23
Well I did the test anyway and got some interesting results.

First, I cooked up the Trek 700 with 250mls, but this time put the lid on. It came to a rolling boil in almost exactly 2 mins, ...20 seconds quicker than before - but it should be noted, that the stove had been turned off, then on again, so I cant be sure the flame was set the same.

Then I tried the teflon crusader, 2 mins 10 secons, that was quicker too, maybe because it's black, maybe because the flame of the stove was different - I cant be sure.

Here's the interesting bit.

Next, I turned the flame of the stove down real low, about a low simmer. I put 200 mls of water in the trek and popped it on there. It took 6 mins 45 seconds to reach a bouncing boil.

Next up, the teflon crusader, 200 mls of water and whoa 5 mins 50 seconds, nearly a whole minute quicker than the trek.

I thought this was odd, so I repeated the trek test and got almost exactly the same as the first attept, less than 5 seconds different at 6 mins 40 something.

The crusader boils quicker on a lower heat - quite a bit quicker too!

I'm guessing this has something to do with the larger mass of the crusader, it stays hotter longer than the thin Ti mug, it probably keeps the heat in better, so aids cooking on a burner with low output. I'd bet the difference would be even more profound on a hexy stove.

It seems on a high energy burner, the thin Ti mug is better, but on a low energy burner, the greater mass, and therefore better insulation of the steel mug, works in it's favour.

I still felt the crusader was a better cooking pot, though that horrible teflon coating makes the water taste foul - it stinks too. I've washed & scrubbed it several times before, but just cant get the taste out of it.

I figure if meths/hexy is your bag, the crusader is a better bet, it's certainly a better cooking pot because of the handle design and stability from it's weight. But if gas is your thing, the Trek gets my vote. I suppose it all depends on how you like to do your thing. :wink:

I'd hazard a guess that you are seeing this is because of the poorer thermal conductivity of Ti and TI alloys ... on a roaring burner it can supply enough energy to the Ti to pump the energy through the alloy into the water, but at the lower energy end much less is getting through the metal into the water, it is instead being dissipated by the surface metal. Given that a gas burner (even at a low heat) is far more directional than a hexy flame, I'd expect even poorer performance from Ti ...

Given that a gas burner (even at a low heat) is far more directional than a hexy flame, I'd expect even poorer performance from Ti ...

Possibly so, but I think the mass has something to do with it also. When boiled ater is tipped out of both mugs, the Ti cools much faster than the crusader. If they were the same mass, the Ti would cool slower, with a poorer thermal conductivity. So the faster cool, must be due to it's extremely low mass & thin walls.

So let me get this right, on low energy burner, the thin walls (poor insulation) and poor conductivity of Ti, means that it takes more energy from the stove to heat the contents, as more of the energy is being lost to the environment.

However, on a high energy stove, the effects of poor conductivity of Ti are overcome, the thin walls of the pot now work in your favour to allow a faster heat transfer into the food.

I think Sargey is right, for a good all round option, a SS billy, with Ti mug is good.

But I have to say, if I was stuck in the middle of nowhere, with nothing but a few matches a knife and my choice of mug, I would opt for a crusader over a Ti mug every time. I suppose that would be the bushcraft way. But it's hard to ignore the convenience, weight saving, cleanliness and speed of s Ti/gas combo. For knocking up a quick brew while on the move, the latter is tons more convenient, if a little less "bushcraft".

Adi007
12-04-2004, 19:04
There's a simple test for thermal conductivity ... fill both with boiling water and test the surface temp of both mugs - the cooler the outside, lower the thermal conductivity (if you want to reduce on the effects of air conduction through the top, put some foil over the top). The heat trying to get into the mug will have as much trouble as the heat trying to escape.

There's a simple test for thermal conductivity ... fill both with boiling water and test the surface temp of both mugs - the cooler the outside, lower the thermal conductivity (if you want to reduce on the effects of air conduction through the top, put some foil over the top). The heat trying to get into the mug will have as much trouble as the heat trying to escape.

I'm really intrigued now...

Oh, without doubt, the Ti is cooler.


This stuff addles me brain. :wink: :-D

Me too!

I know you need about 4.2 Joules to raise the temp of 1g of water by 1 degree Centigrade (at standard temperature and pressure), that a Watt is 1 Joule per second and that a gas stove pumps out about 2500 - 3000 watts, this means that if you had an efficient system, you could boil 500 g (or 500 ml) or water in about a minute.

But beyond that I dunno either ...

... I'm off to have a cuppa!

Yeah, that'd be the specific heat capacity of water right? But what I cant work out, is what part is played by the pot?

Yeah brew time - I'm using my russel hobbs. :lol: :-D

y'know this discussion is scarily familiar to one I had a while ago about the relative merits of heatsinks - that addled me brain too. :-D

Maybe we should market a BCUK Ti heatsink!

Yeah, dont waste all that energy from your processor, insulate it with a Ti heatsink - just like insulating your loft saves energy. Hmmm, works for me. :lol:

The Ti mugs might take a bit lonnger to boil sometimes but how long does it take for s/steel to cool down enought to be drunk from.

Has anyone timed it from lighting stove to getting a warm drink down you?


If i want to keep a drink warm for a while I use an old Aladin insulated plastic mug with lid - it'll keep a brew warm for 20 minutes or so. It a bit bulky but light weight plus it has a a wide base so is difcult to know over even on uneven ground...

... except for inside a tent for some reason.

I have an Aladin mug as well and they are bulky but if you are able to light fire and have a small can to heat the water they are not bad. The lid seals them tight so they make good storage for your brew kit as well.

Plus 20mins gives you plenty of time to set up camp while still having a hot cuppa to sip as you go. Keeps things cool as well.

I somtime us it on the train to work when I'm sometimes late (OK when I'm often late)

It's all right for you. I have ended up ordering a mug and spork for £33 when I was really interested in a billy can / cup combo. Still at least it will be something to store my stove in.

I'm still wondering what type of titanium they use for this stuff ... it seems pretty soft to me and if I compare the spoon I've got to Ti alloys I've got and seen, it certainly seems pretty soft in comparison. Taking a peek though some stores and catalogs I've seeing the word "aircraft" grade Ti mentioned (which is normally Ti 6Al4V or Ti 6Al6V2Sn) - looking at the price, hardness and poor thermal conductivity of this stuff I really doubt that it is "aircraft" grade at all and fear that this is just a repeat of the "surgical" steel thing - marketing driven advertising!

Here is an interestig chart I found on the MSR site:

Notice how the Ti stuff gets a lot of 1-stars ... :?:

More questions than answers!

By multifuel, what fuels do you mean? Petrol?

meths, hexy blocks and greenheat gak.

can't remember how much it all weighs, practically 50 grams. 8-)

i hope to do a how to the weekend.

cheers, and.

I was in the lakes for the weekend, and popped into Ambleside - the mecca of outdoor supplies! Every outdoor shop i could think of within a hundred yards !
Anyway field and Trek had the Snowpeak reduced by £5 and it looks like a nice kit (for a gas type burner), and comes with a little mug that looks ideal for a brew up.

IMHO It may be suitable for bushcraft is placed directly in the fire, but no good hung over it, as it is tall and thin, so has a small surface area on the bottom to receive heat. Making it ideal for the small stove heat source. But for cooking on a fire a larger diameter - short fat type of pan is better.
This titanium kit is lovely but completely unnecessary unless you plan an everest expedition. So anyone know for a cheap SINGLE SKIN stainless mug ? I don't own a NATO water bottle, so don't require a crusader.
My ali pans that i have had since i was 12 are still going strong, and came with wire handles to suspend them. So no need to replace them.
And as a sweet little teapot for yer "green tea" in stainless as requested, i liked this one

it may be cheaper wearing a Seagull badge tho.

Hey Rich,
As an alternative to the crusader, I use the american steel mug.
They run for £5. They fit in the british hexi mug holder with 1cm gap at the front, and have a bigger flat bottom, which is more stable and better for over/on fires. I manage to stuff enough tea/coffee and noodles in it for a whole day out, and could almost shove it in a pocket.

If anyone's interested, Oswald Bailey's are haveing a sale at the mo, and they're doing buy one insulated stainless mug, get one free. They look to be solid mugs and come with a removable rubber coaster and a lid as well. The BOGOF mugs are about £4.95. They also have others including a stainless flask mug with a lid that actually seals so you could carry it in your pack and it shouldn't leak :rolleyes:

If I could just add my tuppennyworth, a few people have noted the advantage of Ti mugs- you can take them from the stove to the lips.

Sorry if I'm missing something here, but if I'm brewing up, when my mug (crusader, stainless, 11 yrs old and still going strong ) boils, the last thing I want to do is put it to my lips. Normally, I pour my water into the plastic mug ( '58, natch ) , and get on with cooking the meal.

When I boil up a brew in the mug, it takes longer for the brew to cool enough to drink than it does for the mug to be cool enough to put to my lips.

Why should the fact that you can't take the can directly off the stove and drink from it be an issue, when I would have thought everyone here would be at least bringing all their water to a boil for hygiene's sake?
