Glass-Paper: Crushed Wine-Bottle Glass, Sifted Into Six Sizes and Dusted on Glued Paper (Tomlinson, 1854)
How 19th-century glass-paper (the 'sandpaper' of the woodshop) was made, from Tomlinson's Cyclopaedia of Useful Arts (1854): broken wine bottles washed, crushed under an edge runner, sifted into about six sizes, and dusted from a sieve onto paper or thin cotton cloth brushed with glue. Sand-paper is made the same way with house sand.

Brush the paper (or thin cotton cloth) over with glue, and dust the glass over it from a sieve, one size per sheet. Venetian red is sometimes mixed into the glue for colour. When dry, shake off the loose grains.

Sand-paper and flint-paper
Sand-paper is made the same way with common house sand of one coarseness; calcined flint has also been used instead of glass. On wood, glass-paper cuts better than sand-paper.

History and honest limits
From Charles Tomlinson (ed.), **Cyclopaedia of Useful Arts** (1854), vol. II, "Sand" (checked on the archive.org scan cyclopdiaofuse02tomlrich, p. 577). He gives no mesh sizes or glue strength; hand crushing and the tools are ours.
