Dragon's Keep in Cold Cast Bronze
So, this is what it’s supposed to look like 
As you can see it worked this time. I measured parts A and B of the resin, poured them into a separate container (one with a round flat bottom) and made sure they were thoroughly mixed before adding the bronze powder. I also used quite a bit less bronze powder, since that was the last of what I had.
I slushed it around in the mold until it started to set, then mixed up my backing layer and poured that in. The picture below is what it looks like when it first comes out of the mold. The bronze powder is dulled by the resin and it’s a chocolate brown color.
Casting fresh from the mold
You have to break down that very top level of resin to let the bronze shine. I’ve seen 000 steel wool and scotch brite pads suggested. I tried both on this – they work, but they’re very messy as they disintegrate so I looked through my sanding supplies for more options.
I tried my pmc bristle brushes, but the brass one didn’t seem to do a thing, and the steel one scratched the resin too much. The best thing I found was a flexible, yellow sanding sponge from 3M labelled extra fine/320 grit.
I’m pretty happy with how this came out. The mold kept all the detail I was hoping for, and the dragon scales look great in bronze.
That’s very very nice!! Thanks for sharing your process!
