I have a few Hirst Arts Moulds and the cavern accessory mould has a bunch of useful stuff and three crystals that I never really could get my head around. I always cast them if I had extra plaster that would have gone to waste but did not have any real use in mind. When I was going through my plaster cast bits looking for rocks for my BSC 2021 I found the pot full of the crystals. I decided to try to figure out something to do with them. After some thought I came up with this ore maker.
I am fairly happy with how it came out so I may pull out the plaster again to make some more.
Hope you like.
