18x18x1.5" Full Size Deep Chess Board Silicone Mold With 1.75" Squares

Looking for a true to life size chess board mold that is deep enough to cast objects in? This massive 18x18" mold is 1.5" deep and features 1.75x1.75" squares that are 0.375" (3/8") in depth. At nearly 8lbs in weight, it uses 10-15 times the amount of silicone used in the common small and thin, Chinese made, chess board molds found on Amazon or Etsy. 

With large 1.75x1.75" squares separated by 1/8" lines, both 3/8" in depth, you can create solid, thick squares with ease using alternating resin, concrete or Jesmonite colors. Once your small squares are set, you can then pour an additional layer (which will end up being the base of the chessboard) to solidify all the squares and surrounding border together. This layer is also deep enough to cast objects, or even encapsulate flowers in. The total thickness of the finished cast board with this mold can be up to 1.5".

Once you demold this piece, you can leave the separating lines unfilled, fill them with your choice of resin, or sand then flood coat your entire finished chess / checkers board.

If you are looking for a chess board mold that is just as functional, but don't need the extra depth check out our 19x19x0.5" Chess Board mold with 2" squares that we also offer.

We do not currently carry any chess player / chess piece molds. However, we recommend the large 3D printed chess pieces crafted by Spectra 3D Technologies.

Crafted Elements Silicone Molds

The last mold you will ever need. Created just for makers, resin artists and wood workers, these time saving flexible yet durable silicone molds significantly cut down on the setup and demolding time usually involved with other molds. Silicone molds are superior to wood and tuck tape, and HDPE molds because:

• They can be used with epoxy resin, resin and wood, concrete, Jesmonite, plaster and more.
• They never need assembled, or disassembled. Saving huge amounts of time.
• The strength and flexibility of the molds allows you to insert and remove pieces of wood easily.
• The corners and edges never need sealed.
  
• When using wood, the wood stays in place, tight in the mold if you cut it 1/16" larger than the width of the mold. Preventing the need for clamps or weights.
  
• The mold is heat resistant to ~450F. Avoid direct contact with the flame of a torch. Briskly wave your torch or use a heat gun to pop bubbles.
• The molds are reusable. However silicone molds do have a finite lifespan when used with epoxy resin, but getting 20-30+ castings out of the mold can be expected when they are properly cared for and a non-silicone based mold release spray is used.
• Like HDPE, epoxy resin does not stick to silicone. However, the heat generated by the exothermic reaction and the chemicals in epoxy resin are very harsh to all silicone molds. Additionally, if part of your epoxy has not fully set due to improper mixing, the epoxy can become bonded to the mold. Both of these factors can lead to mold tear out when removing your piece from the mold, leading to pits and tears on the surface of the mold. This is why we a non-silicone based mold release spray is required before each pour. To help prevent tear out and to increase the life of your mold. We use the 'MG Chemicals 8329 Non-Silicone Epoxy Mold Release', 'Smooth-On Ease Release 200', 'Mann Ease Release 200' or 'Mann Ease Release 300' which are readily available from Amazon and other online retailers. Cooking spray, vaseline, silicone based sprays or sprays designed for urethane or polyester products should NEVER be used. Using a proper, non-silicone based mold release can mean the difference between getting only a couple of uses from your mold to 20, 30 or more.
