Carving Wax Shrinkage

The talc ingredient in the carving wax helps keep shrinkage to a minimum, however, there is still some shrinkage. The cue ball I used as a pattern to make the hip joints is 2.25 inches in diameter. The carving wax balls I cast in the moulage mold came out 0.0625 inches less in diameter. That is about 1/16th of an inch in 2.25 inches, or .02777%. Almost 3% shrinkage.
