All sculptures from Terrance Patterson Gallery are made from Hydrocal, a gypsum cement. Hydrocal is a trade name for a casting cement, and is manufactured by U.S. Gypsum. 

Hydrocal comes in a powdered form which is added to water, mixed until it is of the consistency of cake batter. It is then poured into a latex mold and bounced, rolled and agitated to remove all air. It is then allowed to harden by catalytic conversion for 40 minutes. It is then removed from the mold and all seams are trimmed and filled. It is then set aside for two days to dry. The dried sculpture is then dipped in black dye and allowed to dry another day. 

Skilled artisans apply the bronze Patina by hand to each piece, then it goes to the paint booth for a coat of clear acrylic which sets the bronze Patina. 

To care for your sculpture simply use a spray wax and buff with a soft cloth. The finish will become richer and more beautiful with each waxing. Never use soaps or solvents to clean your sculpture.
