Awhile ago, I posted a piece I did of author, H.P. Lovecraft.
It was sculpted using Monster Maker’s clay, something I’ve recently been experimenting with, and found it held small details at this scale quite well. As you can see, it’s very, VERY, small, and I had a blast sculpting this.
I made a simple block mold for it, and pulled some casts to see how it translated. It came out with all of the small details intact. Below is a cast using the same metal powders as the wall relief.
