Cast Resin Sculpture
Casting resin can be a long process, involving a number of steps. Some form of model is usually made first, often-using clay or plaster. Then a mold is formed. I often used plaster for the molds, which was usually destroyed when removing the cast resin. During the 60's and 70's, I worked mostly with polyester resin. Some of these casts are rather large volumes and it took a good deal of experimentation to be able to make good casts. The surface quality was not always very good, so a lot of hand finishing was required. The polyester also had an odor, which permeated the workspace and remained long after the work was done. I haven't used the stuff in many years. Polyurethane resin is what I use currently. --Billy Hiebert
