Use talc powder to lightly dust the Mold Max® 60 molds in order to reduce surface tension. Reducing surface tension enables the molten metal to flow evenly around the mold surface. Be sure to brush the talc evenly into all areas. Remove any excess powder by tapping the mold on the table top. Use an airhose to eliminate any accumulation of talc in the details. This will leave a very fine coating of talc in the mold.
