4-piece Triangle Geode Coaster Mold

Sale price $8.00 Regular price $10.00

Get your resin ready because it's time to make some geodes! Create a large geode that becomes four individual pieces! This mold is seriously hot!!!

Measuring 8.3" x 8.3", 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.

    Awesome mold

    This is a great mold. Came super fast and each mold came in its' own zip pouch/wrap. Price was perfect. Definitely will order more from here. Even got a sweet email from the owner after my purchase just to say thank you. That shows pride in their shop. Very happy.
