Metals/Inorganics in Plants
The use of the words chert vs flint in the States to describe
cryptocrystalline quartz is based on regional speech variation and state
of manufacture, not color, luster, or any objective standards.
Archeologists and those referring to human worked rock generally use
flint or flints.
Therefore, chert nodules can be worked into flint arrowheads.
Nobody said it had to make sense.
