The sculptures were molded in Ultracal 30 and preheated prior to casting. The molds are preheated to ensure the appliance edges stay thin since molten gelatin begins to set up as it cools. Both ape appliances were cast in tinted gelatin.
To tint the gelatin I used red flocking powder and light creme cake makeup powder to give the skin a lifelike appearance. It took several tries before I got the edges as thin as they were in the photo below.
I will post more photos when I apply these makeups in April.
