Casting Temperature: These molds have been successfully tested with temperatures of up to 194°F without warping. However, we recommend using an accurate thermometer and keeping pour temperatures as low as possible. (Recommended glycerin base temperature is 140°F.) Lower temperatures prolong the life of the molds and also prevent warping.
Unmolding Times for Melt and Pour Base: Most melt and pour soap can be unmolded after four hours at room temperature. If it is still slightly difficult to remove the soap after four hours, waiting longer or using the freezer or refrigerator method (described below) will make it easier to unmold.
Filling and Unmolding: We recommend slightly overfilling the molds so some of the soap can be seen in the funnel. To unmold, gently pull the two halves of the mold apart while steadily twisting the mold as you would with an ice cube tray. This twisting action will break the seal and release the soap. Use a sharp knife to pare away any excess at the funnel end and any rough edges along the seam line. (A fingernail works great, too!)
When using melt and pour, if you're not having success with the manfacturer's recommendation to wait approximately four hours before unmolding, try putting the soap-filled molds in the freezer for approximately fifteen minutes, or in the refrigerator for approximately one hour. Don't let the temperature of the base drop below 55 to 60°F... temperatures lower than this may result in the base sweating. After removing the molds from the freezer or refrigerator, unmold using the method previously described. The soap should easily pop out.
Unmolding Times for Cold Process: For best results, don't try pulling the two halves of the 3D soap mold apart until the soap has fully solidified (at least 24 hours). Then unmold using the same techniques as for melt and pour. Cold process soaps usually require more time in the freezer.
Cleaning 3D Molds: Wash in warm, soapy water. We do NOT recommend putting the molds in the dishwasher.
