The Quartz Page Flint and Chert

Feb 16, 2012Flint is hard, and has no preferred direction of cleavage. Flint has a tendency to split into pieces with a curved but even surface. Flint has a homogeneous structure and its surface is smooth and not grainy as most rocks. It is thus much less susceptible to grinding. Flint is quite tough and not as brittle as crystalline quartz.
