With warm weather approaching and a class of middle schoolers with spring
fever, I am thinking about doing some plaster sculpture. I think I will
introduce "public art" and have the kids design a "site specific" plaster
sculpture. I thought we could go outdoors to do most of the carving, thus eliminating
much of the mess.
Question - - - is best to allow the plaster to dry out before sculpting
begins? Or should we keep the plaster damp by storing it in a baggie? I am
thinking through the process and just wonder how long the plaster should dry, or
if it should dry, after removing it from the form before carving begins.
