4.3” Round Silicone Coaster Mold - 4 PK

Regular price $18.00

LIke our other round coaster molds, the simple elegance of this shape is undeniable.

These are slightly larger than our 4" Round Silicone Coaster Molds (as the name would suggest) and come in a 4 pack, because one mold just isn’t enough! They make great oversized coasters, ornaments and trinket dishes when paired with our shaping balls, crystal molds, bear molds, etc.

Measuring just over 4.3” in diameter and .3” deep, 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.

    Love the size however one mold had a scratch in it that caused me to have to topcoat. It could have been caused from not being well packaged.
