Easily create resin coasters to look like a geode slice with an open center using this reusable silicone coaster mold.  The mold can help you make matched resin coaster sets to gift or sell!  Coasters made with this silicone mold measure 5 inches across by 1/8 inch thickness. The center is open approximately 1 3/8 inches by 1 inch.

How do you make open geode resin coasters with this mold?

Step 1:  Accurately measure and thoroughly mix a casting resin

Step 2:  Color the resin, then add to the coaster mold

Step 3:  Demold the coaster and finish as desired

Agate slice coasters shown were made with the Resin Obsession super clear resin, Pearl Ex magenta, Resin Obsession opaque white pigment, glass chips and dark pink glitter.  The geode edge was highlighted with a silver paint pen after demolding.

For the best results and to prolong mold life, we recommend using our Ultra 4 Parfilm Polyester paintable mold release.
