Mark Prent

This artist seems to be of acclaim in the dark surrealist art underworld. Here's a quote from his website http://www.markprent.com/ :

"Mark Prent is still making sculptures, but his materials-of-choice have changed from polyester resin and fiberglass to pigmented silicone "skins" over gypsum-polymer "skeletons." The technique involved is similar to the signature method that he developed in the early 1970's with polyester resin, that of builiding-up multiple reverse layers of translucent pigmented material to achieve a believable vitality in the cast positive."

The idea of building up layers of translucency may be a nice idea with different ratios of resin and slate powder....
