Yes, for silicone models featuring relief cuts or multi-part assemblies, you should properly support the exterior structure before filling to keep the seams closed. When your casting has cured, carefully ease the finished piece out along the designated seams to protect both the mold and the fine details.
Always handle detailed cavities gently by slowly rolling and peeling the flexible silicone away from the cured casting rather than pulling the piece out forcefully. Taking your time around protruding features, such as wings or animal ears, prevents delicate areas from snapping and keeps the mold from stretching excessively.
Yes, this collection accommodates a wide variety of cold and warm pour mediums, including melt and pour soap, cold process soap, gypsum composites, plaster, casting clays, and concrete. If you choose to work with resin, pouring the mixture in stages helps you achieve crisp surface details and clear ornamental casts.
Wash the cavities with warm soapy water after each use to clear away any remaining wax, soap residue, or plaster dust, avoiding abrasive pads or stiff brushes that could scratch the surface. Store your clean molds flat in their natural resting shape, well away from direct sunlight, open flames, and heat sources to maintain their flexibility.
