ABSTRACT:
A method of coating a surface of an article block includes utilizing a mold that has its interior surface electrolessly coated with a metal such as nickel where the mold is made from mild steel and further includes depositing a resinous composition in the coated metal mold and then inserting a surface of the article and then subsequently curing the composition by exposing the mold to heat; the exterior surface of the mold is oxidized and darkened to increase the capacity for the mold to absorb radiant heat; a method of preparing the mold is provided where the mold is electrolessly coated with the metal while the exterior surface thereof is masked to prevent the deposition of the coating metal on the exterior surface.
