Coal Extenders (clockwise--brown rot, Sulphur Shelf fungi processed by fungus gnat larvae, white rot) ![]() Jeff carefully inspected the length of the hearthboard, along which were circular sockets of varying depth and charred condition. A triangular notch, cut all the way through the thickness of the board with a piece of sharp stone, connected each socket to the board’s edge. The arrangement of the socket and notch are reminiscent of a traditional-style keyhole, with one point of the triangular notch intruding into the round socket. Selecting one of the newer, shallow sockets, he placed the hearthboard on the ground, taking care to avoid any moisture laden grassy areas which would conduct heat away from the hearthboard and render the attempt at friction fire much more difficult. To control conditions further, Jeff placed a thin piece of bark underneath the socket and notch that he would use to house a rotating wooden spindle in hopes of coaxing a glowing coal from desert wood. |

Flint and Steel On Powdered Sulfur Shelf Fungi Momentarily fingering the deep calluses on his palms, Jeff turns his back on the prevailing wind in order to shelter this ancient attempt with his body. Picking up the spindle, which is still wrapped once by the bow’s cord, he places one end of it into the socket, while the hand-hold is brought to rest on top of the spindle’s other end. The spindle is sandwiched between the hand-hold and hearthboard, perpendicular to the ground. With one foot on the hearthboard to steady it, he gently, steadily pushes and pulls the bow, toward himself and away from himself, again and again, allowing the spindle and hearthboard socket to warm up as friction slowly carbonizes and disintegrates the cell walls of the fan palm wood. These small, darkened, powder-like wooden particles, or char, which will fuel the future coal, fall into the notch—the notch protects the char from energy-sapping wind and allows heat to accumulate here from the frictional process.
