Fine Sharp Sand: Dug from a River Bank, Burnt in Balls and Hair-Sifted (Tomlinson, 1854)

Fine quartz sand the way the Sheffield cutlers prepared Trent sand: sharp river-bank sand made into balls, burnt in the fire for a few hours, then crushed and passed through a fine hair sieve; burnt sand was held to cut faster than raw.

"Trent sand is a fine and sharp sand, collected from the banks of the Trent."

Choose and dig

Take river or pit sand rather than sea sand: it is sharper, while sea sand has been rounded. Pale sand is purest (colour comes mostly from iron oxide).

History and honest limits

From Charles Tomlinson (ed.), **Cyclopaedia of Useful Arts** (1854), vol. II, "Sand", pp. 576-577 (checked on the archive.org scan cyclopdiaofuse02tomlrich). He gives no fire heat or ball size; the dust warning is ours.
