Round Geode Silicone Tray Mold - XL

Sale price $24.00 Regular price $34.00

This large round version of our geode mold series is perfect for creating custom art pieces or big round resin trays. 

This mold is 13" in diameter and is gorgeous!!!

And like most of our products, this mold is made of food-grade silicone, is BPA free and non toxic. It's flexible, soft and heat resistant.

Let your imagination go wild with this ultra cool jumbo sized mold.

This mold takes up to 18 fluid ounces of resin (you can use less if you don’t want the tray to be that thick - our preference is between 16 and 17 fluid ounces of resin).

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.

    Everything I wanted in a round mold- size is perfect, sides are on point and silicone is thick enough to support resin and gives all my pieces a beautiful shine. Thank you for keeping your prices reasonable. Many artists are building up their product and funds are nonexistent. Arrived fast and always a little something extra(love it!)
