Crushing and Grading Charcoal

Lump charcoal comes in pieces from fingertip to fist size. A forge or a smelting furnace burns evenly only on pieces of one size, so the lumps are broken in a sack and sieved into grades. Bloomery smelters break it to about 2.5 cm and sift the fines out through a 1 cm (3/8 inch) mesh; the fines are kept for the furnace base, for insulation or for the garden. Weigh each grade: the split tells you how much of a sack is usable at your size.

Choose the size

Decide the largest and smallest piece you want. For a bloomery: no larger than 2.5 cm and nothing smaller than 1 cm. A forge fire takes the same range or a little smaller.

Break it in the sack

Put the charcoal in a burlap sack, fold the top over, lay it on hard ground and strike it with the wooden mallet. Turn the sack and feel the size through the cloth; stop while most pieces are still larger than you want, or it all turns to dust.

Sieve into grades

Sieve the lot through the coarse screen: what stays on it goes back in the sack. Sieve what passed through the 1 cm screen: what stays on top is your crushed charcoal, what falls through is fines.

Weigh the grades

Weigh the crushed charcoal and the fines. Write down the share of each: it is the sack's yield at your size.

Store dry

Let damp charcoal dry in the air, then store each grade in its own lidded metal bin, labelled. Wet charcoal spits and burns cold.
