Triangle Silicone Coaster Mold - 4 PACK


Regular price $20.00

This oversized triangle coaster mold is sure to please! The rounded corners keep your resin moving in interesting ways with a super shiny finish!

And they come in a 4 pack, because one mold just isn’t enough!

Measuring 5” in diameter, these molds are

  • Flexible, soft and reusable
  • Made of BPA free silicone
  • 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.

    Great shape

    Have not used them yet, but I plan on making a faux terrazzo coasters with them soon. As soon as I saw the shape, mid-century terrazzo came to mind!
