Plaster Casting and Waste Molds
A waste mold is just that, a mold that will be wasted or destroyed after usually only one casting.
It is generally the first mold a young sculptor learns to make. It is quick and inexpensive to make.
The following images and descriptions are of a waste mold made off a sculpture by Albert Wein titled "Diana". This was actually one of my most favorite molds I have had the pleasure of making. I also enjoyed working with Mr. Wein and learning his process.
Mr. Wein and a number of his peers would create a clay sculpture, make a plaster waste mold, refine the mold and make a plaster cast then refine the cast before making a rubber mold for casting in the lost wax process. This process is hardly done today. Most sculptors just have a rubber mold made off their clay.
