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.

    Fun fun fun

    This mold is great go to mold. Every resin artist should have one. It’s the “little black dress”of molds. You can never go wrong with this geode mold. The 5th design means you have an extra one just in case- all in 1 big mold so you can’t misplace one. Best of all is the price!

    Favorite geode mold

    This has become my go to mold when making geode coasters. They are the perfect size and having 5 on 1 sheet means no more wasted resin. Great price and it arrived super fast

    I finally had an opportunity to use my silicone coaster mold. I love them. The resin cast was very easy to remove.
