Anyone who’s ever done any molding and casting knows how expensive molding rubber is and how aggravating it can be to be pouring a mold and come up short with your mold mix.
In this Robert Tolene video, he offers a tip I hadn’t heard of before for saving on molding materials. He calls it “dunkin’ chunkies” — cutting old molds pieces into small chunks and adding them into a new mold pour (in the voids where they won’t interfere with the object being molded).
