Black Chalk

is an indurated clay, of the texture of white chalk, and chiefly used
for cutting into crayons. Fine specimens have been found near Bantry in
Ireland, and in Wales, but the Italian has the most reputation. Crayons
for sketching and drawing are also artificially prepared, which are
deeper in colour and free from grit. Wood charcoal is likewise cut into
crayons, that of soft woods, such as lime, poplar, &c., being best
adapted for the purpose.
