Surface Finish: Smooth/Glossy

This listing is for 1" Deep Rectangle Molds. There are 24 different sizes available. These molds are ULTRA Quality and Long Lasting!

We suggest using mold release to extend the life of your silicone mold. It is not needed, it is recommended. We suggest Ease Release 200. Please note that mold release does affect the surface finish by removing the glossy surface on the mold. It will make the mold surface finish satin/matte which directly transfers to your casting.

Please message us with any questions you may have regarding this mold.

**Please note this listing is for the silicone mold ONLY.

Our silicone molds cure to a strong platinum rubber which is tear resistant and exhibits very low long-term shrinkage. Our molds will last a long time in your mold library and are good for resin, concrete, wax, gypsum and other materials. The molds are heat resistant up to 450 degrees Fahrenheit or 232 degrees Centigrade. They are suitable for casting low temperature melt metal alloys.

SILICONE MOLD CARE INSTRUCTIONS

• DON’T TOUCH the inside shiny part of the mold. This will cause permanent scuffs that will show in your final cast.
• Use scotch tape to gently clean the mold. Tap the spot lightly where there are loose particles.
• USE EXTREME CAUTION when using a torch/heat gun to pop bubbles in the resin. It may rip the mold upon demolding your fully cured resin. Instead try a mist of alcohol over the resin.
• Make sure the resin is fully. Uncured resin may rip the mold.
• Please follow all safety precautions when using resin. It is very toxic.
• If you have further questions or concerns about your mold, please shoot me a message and I’ll get you taken care of.

PLEASE INSPECT MOLD PRIOR TO FIRST USE. I DO NOT ACCEPT RETURNS OF USED MOLDS.
