How much of your silicone should I use? 
It depends on your model. We recommend that you surround your model with 1cm of silicone to make it very resistant to tearing. The amount needed can be calculated as follows: For a model of 4cm3, I have to make a box of 5cm3. Just tell the difference between the volume of the box and the volume of the model. 
1cm3 of our silicone weighs 1.5 grams. 

Would you have a recipe for cold porcelain? 
There are several but here is the one we prefer to use: 
  • 200g vinyl white glue 
  • 140 grams of cornstarch
  • 1 tablespoon rapeseed oil (for flexibility) 
  • 1 tablespoon white vinegar (for storage) 

  How to use your crystal clear resin? 
When you purchase, you receive two bottles. The first is the resin. The second is the necessary catalyst for the chemical reaction of the curing of the resin. 
  1. First, protect yourself! Put on gloves before using this product. 
  2. Before opening the bottle, shake to homogenize the product. 
  3. Weigh a thoroughly two times greater than the resin amount cataliseur. For example: 20 grams of resin for to 10 grams of resin catalyst. 
  4. Mix the two products and add your dye. 
  5. Pour the mixture into an appropriate mold because the resin is corrosive.
