i bet it was big back in Egypt.
This seems like quite a good mineral to carve high detail microcarvings on due to the low hardness and apparent lack of chipping flaking. Do you know of any other low hardness minerals that would be good for this sort of work? Thanks for the informative video!
Good question! Gypsum is soft enough to scratch by hand, but any mineral below a 7 on Moh's hardness scale would be easily scratched/etched with simple tools.
@@GLGMineralogy Thanks! the microcarver I know only works with things Mohs 4 and below, as his carvings have detailing that is literally microscopic and it is hard to hand carve such details accurately at higher hardness. That obviously restricts the options quite a bit compared to having options from Mohs 5 to 7. Still, it seems like Gypsum at least is quite a nice material for this =)
