Square Silicone Coaster Mold - FLAT

A great option for a flat square coaster mold and perfect with our Druzy insert.

Measuring 4" x 4", these molds are

• Flexible, soft and reusable
• Made of non-toxic food-grade silicone; BPA free
• Heat resistant: -40 to +446 degrees Fahrenheit, (-40 to +230 degrees Celsius)
• Non-stick for easy release

Tips (always follow instructions for the resin you are using - these are meant as general guidelines):

• Always pour your resin into the hardener (pour hardener into the mixing container first, then resin). 
  
• Stir resin with a plastic or silicone stirring stick to reduce air bubbles. Wood is not recommended as it can create air bubbles.
• Let resin sit a few minutes after stirring to reduce air bubbles.
• Don’t use a torch or heat gun as it could damage the molds and make it difficult to de-mould, causing them to tear - this is especially true near the edges.
• Wash mold as needed in warm soapy water.
