Western shale master casting for all multi-scale applications. Modeled from Colorado 'Oil Shale' may be used for Eastern Allegheny or Pennsylvania models. Approximately 8"H x 6"W x 1" thick. MASTER CASTINGS are high density polyurethane reproductions of actual rock formations from around the U.S.A. Great care was taken to hold the most intricate details. These lightweight castings may be easily carved, painted and mounted directly on your layout with minimal effort. They may also be used as 'Make-A-Mold' masters for making highly detailed latex molds.
