My freind found this renovating his house

No idea what this is. He hopes it's gold, I just hope it's not asbestos

If it is dropped from high enough won’t it cool on the way down and not do that? Like when they make lead shot dropped from towers?

If the gold is at 1950 F and cools to 1940 F in air - which should be a very small amount of time given the huge temp difference - then air cooling would work.

They used to make lead shot by dropping molten lead from large towers. It was very consistent once they had it down to an industrial process
