Heart Mold 887 is made of durable, reusable polyethylene. When completely filled, this mold holds about 3/4 oz. of resin. It will produce heart castings that are approximately 2" x 2" x 1/2" deep. Note: If you are trying to determine the difference between this mold and heart mold 851, heart mold 887 has a straight edge whereas heart mold 851 will produce castings with a curved edge.
How to Use Resin Molds: Remove any dust and particles from your reusable mold. Molds do not require mold release when casting with resin, however, it is strongly suggested. We recommend the use of Castin' Craft Mold Release and Conditioner. Protect your work area with freezer or wax paper. Treat mold with mold release and allow to dry. Place mold on a level surface and fill the cavities to just below the top. Once the pieces are cured, turn the tray over and press the center area of each piece while flexing to release the casting. Do not use sharp objects to demold your resin as you will scratch your mold. Be sure to also read our plastic resin mold care tips to ensure a long life for your molds.
