1-piece Geode Coaster Mold

Sale price $5.00 Regular price $7.00

Make beautiful coasters with this Geode Coaster Mold with built-in center.

Measuring 5.1" x 5.1", 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.

The square mold is beautiful and without any mars, nicks, or scratches. It's perfect. I've not had a chance to use it yet. The only thing I wish suppliers would do is put the ounces of resin their molds will take to fill. Other than that, I'm very happy with both molds.

It isn’t as big or able to really make the mold I wanted.

I’m very happy with all the products that I’ve purchased, and particularly like the Geode molds, I’ve posted some on Instagram and Facebook, Flow Art By Trish. I would highly recommend all of your products. Trish
