Chavant Plasteline Modeling Clay

This is my first experience of working on a large scale piece using Chavant Plasteline. I must say that the expense is well worth it. In the past I have used water based sculpting clay and the need to keep the clay damp and covering and uncovering the piece all the time was a real time consumer. I have also made my own plasteline. This is a mix of dry clay and used motor oil. You guessed it, a stinky mess. That material worked OK for taking up space in resin bonded sand molds but I didn't want to risk the heavy sulfur content during this project. Sulfur in clay is incompatible with the flexible rubber mold materials I will be using.

I have found the Chavant to be nice to work with especially when heated with a lamp. I have also used a heat gun on the sculptures to soften the surface. When it cools it tools well and holds texture nicely. I have a ways to go on this project till I'm ready for mold making but the material has become a partner in the process rather than an element I must struggle with.

I'll start on the shirts tomorrow, with a couple days off for Christmas I still may be finishing the clay at the first of the year. Happy Holidays.
