More Tips to use with Epoxy Resin:

1) poured in silicone molds in layers, allowing air bubbles completely escape;

2) to expedite the process of escaping of bubbles and time of solidification of resin, the mold can be a bit warmed up, for example, heat the oven to 80°C, turn off, ventilate it a little and put mold, filled with resin in the oven.

3) follow resin instruction for the time need to cure, measure and mix resin properly. It does not mean it has been cured if it is hard.

4) do not use water-base ink for resin casting.

5) After baking clay / resin in complex or deep molds release the finished product under running water with soap.

6) Put in refrigerator a while/ soak in hot water a while/ release with baby oil if it is hard to release.

FAQs:

What is advantages of silicone molds and the different between silicone and plastic molds.

1 Flexible. Silicone molds allow you to do very complex castings that can be released much more easily as compared to plastic molds.

2 Castings may come out more shiny than a plastic mold.

3 Durable. Not easily scratch the surface as plastic mold. Silicone mold can last for years and thousands of casting if cared for properly.

4 Silicone molds should be cleaned after use and stored flat in a cool, dry area for protection reason. ( if you want to use thousands of times ).
