I hear what you are saying but what, then, is the appropriate material
for making a mold for something like lost-wax casting of metal thingies?

I could probably research it, but it is easier to just ask here.

Get investment from a jeweller's supply place. It can retain very
fine detail, and it can handle metals as hot as platinum. You need
an oven to bake it out at 1200 to 1400F (follow the directions on the
bag) before you pour hot metal in it.
