>>1198797I went to public school, anon. We didn't spend much time learning to identify hematite in the field or how to build a Mohr kit. Clay doesn't have a luster last I checked, either.
>>1198637>>1197366Exactly, great tool material (flint is actually a type of quartz) and much more common down here in the South. Also crushed quartz (eg sand) has a very high grit due to its hardness, perfect for sharpening.
>>1198723>>1198724In Florida the "soil" is almost entirely sand and limestone, hence why I'm totally unfamiliar with clay. Can't even make proper mud with it. Doubt you'd find anything in the way of useful minerals that wasn't leftover from human development. This would mostly be applicable for going up north past Alabama/Georgia where the woods aren't just miserable swamps. At least I can mine for fish down here...
