ABSTRACT:
A process for manufacturing a capital for an architectural column. The inside of a mold for an architectural column is lightly coated with a mold release. A first opening of the mold is placed upon a surface, and a plug is positioned on the surface within the first opening. Through another opening foam is poured around the plug. After the foam has hardened, the mold is removed from the surface. All other openings in the mold are securely covered. Then an elastomer is introduced into the mold, and the mold is rotated about multiple different axes. The introduction of the elastomer is repeated after the prior coating created by the introduced elastomer has become tacky but before the prior coating has become firm. After the final coating of elastomer has become tacky but not firm, foam is introduced into the mold.
