Melt Swedish granite or gneiss?
Not possible with a wood fire.
What happens is the surface develops cracks, that the ice fractures open. If you extinguish the fire and embers properly, by pouring water on it, the stone will crack up.
That is the technique they used in mining in the past.
It is ok and legal to use smaller rocks and stones, of the size you can carry, but making a fire on any larger, and specially the ice age smoothed bedrock, is a total no-no.
Yes, the ice pushed some stones down to you. Your state also own quite a few beautiful, very large stones of the unique Black Granite. It is quite unique because it is homogenous pure, deep black.
You guys paid for them in the 30’s, but never collected.
That stone is very popular as a wall cladding stone for magnificent buildings.
Also called Diabase.
