How to Identify Flint
Flint and chert are cryptocrystalline quartz: dense, waxy-looking stone that breaks with sharp-edged conchoidal fractures — the reason it was the toolstone of choice for millennia. Hardness about 7, so it scratches glass, and it throws sparks against hardened steel. Colors run gray, black, tan, and banded combinations.
