Flint chemical formula.
Both can be used in place of 400-, 325- or 200-mesh flint, but if a glaze recipe calls for 200-mesh flint, 325-mesh flint would be the best option. Some glazes are sensitive to finer grind materials. The smaller mesh materials can increase glaze melt—increased surface area produces more of a reaction with other glaze materials—which might ...

Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO 2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.
Chert vs Flint (EXPLAINED) For about 2.5 million years, humans shaped stones into tools.

It is a softer glass, making it easier to cut into designs that show off its high refractive index. It cannot withstand high temperatures or sudden changes in temperature. In order to determine these densities, we might weigh a cubic centimeter of each type of glass. If the flint sample weighed 7.2 g and the bottle glass 2.4 g, we could describe the density of flint as 7.2 g cm –3 and that of bottle glass as 2.4 g cm –3.
