4” Round Silicone Coaster Mold - 4 PK

Sometimes simple is best, and these round coaster molds scream simple, but are the perfect canvas for all manner of creativity!

They come in a 4 pack, because one mold just isn’t enough! And because these are on the smaller side of coaster molds, they are wonderful for trying different techniques and experimenting with colors because you won't need a lot of resin.

Measuring approximately 4” 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

The finished coaster size is just under 3.5” in diameter and .3” deep  

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.
