All molds are made to order in our studio in Anacortes WA.
Based on the longest dimension of the casting size.
3" x 2" (inside area 2.75"x 1.75" at widest points)
Depth 3/8" (9mm)
Molds are made with Smooth-On silicone, which cures to a soft strong rubber, which are tear-resistant and heat resistant up to 450F.
You will be able to cast resins, wax, gypsum, concrete, soap and other materials with this mold. NOT A FOOD SAFE MOLD!
Since these molds are made by hand there may be slight imperfections, but they will not affect the casted piece.
*Disclaimer- These are acrylic backed shakers, which means two pieces of acrylic are carefully glued together. This also means sometimes there are small glue flaws on the inner surface. We try to avoid these flaws as much as possible. The small marks should disappear when the shaker is filled.
