Hydrocal heat and Chavant lebeau touche
edited July 2017
Please help asap! I need to know if the heat hydrocal produces will melt the clay and ruin my sculpt if I use it to make a mold? Will something like the Jolly King plastaline be better? Thank you!
You should be fine. I've made Ultracal and Hydrocal molds of clay sculpts in monster clay and chavant medium before (which can both melt), and never had problems with melting impacting the quality of the mold/casting details.
I also don't use a ton of stone. The thicker the stone the more heat, and the more your final mold will weigh.
That said, your sculpt will likely be destroyed (or damaged) in the demolding process.
I just wasn't sure if the le beau touche was comparable to the medium. It seemed kinda soft to me. I've never used medium or monster clay so I have no comparison.
