Metal Casting of Sculpture

Excerpt

This book describes in detail, and pictures step-by-step, the various processes of producing sculpture and ornaments in metal by the cere perdue or lost wax process. It gives scores of formulas and methods which have been known only by word of mouth. It exposes trade secrets which have been closely guarded by the worker in the past.

The ever-growing tendency today is to refine hazy verbal descriptions of art methods into specific written formulary. Tested formulary invariably produces uniform results in the hands of a skilled technician. However, the unskilled worker may miss some simple principle, and thereby obtain a faulty result. One novice in the casting profession complained bitterly that all local plaster of Paris was worthless, blaming the manufacturers and merchants. When the novice was asked how he mixed the plaster, he said, "I put the plaster in a bowl and add water. It gets lumpy right away." The experienced worker knows that in mixing plaster, the water is placed in a bowl and the plaster added to it. In this text, I have not only tested and retested the formulary, but I have tried to be specific in mixing directions.

I am indebted to Mr. Randolph Wardell Johnson for furnishing some of the illustrations, and to the various furnace manufacturers, who have provided engravings of their products. I am also indebted to Miss Frances Blackburn, who has helped me greatly in the preparation of the manuscript.
