First Use of Composi-Mold
I love moldmaking. It's in my bones. But.... I also hated doing it in the past because it meant putting on intense safety gear, going outside (shudder), working with material that could harm my health, etc. It was always a dangerous, heavy, cumbersome ordeal, even though I loved working with "cement".
Saw containers of Composi-Mold at my local art supply shop and while it was pricey for me, it was also rated as safe, eco-friendly, and... reuseable! I splurged on a small container to try out so long ago that when I saw it again in the store I bought it again!
I don't use/have a microwave but their site indicated that it would work as well with a double boiler so I did that. I used metal jar lids to keep a small glass bowl off the bottom of the art pan and gently melted down cubes of it. It cut easily with scissors.
Meanwhile, I (mistakenly, but it's alright) coated the sculpt all over with petroleum jelly as a mold release. I used a tin can half-filled with a mixture of wet sand and red clay as a base to hold the back of Urhu's head. I slowly drizzled the melted Composi-Mold over the face of the sculpt hoping that it wasn't hot enough to actually melt the modeling clay. I couldn't tell for sure if he was surviving in there, even through it's handy translucent quality, but I figured even if he distorted from the process it would only make things even more interesting.
Next up: Casting Urhu in Washi Mache, stay tuned!
