How To Cast a Crystal Clear™ Shell in a Mold Star™ 15 Mold
Step 2: Using Mold Star™ 15 Slow for the Mold
Use Mold Star™ 15 platinum-cure silicone rubber for making the mold. The mix ratio is 1A:1B by volume. Pre-mix part B before dispensing. Then dispense equal parts of Part A and Part B, which will be used to make the first half pour. Pour part A into a larger container and then part B into the same container. Mix thoroughly until the color is uniform. Mold Star™ 15 has a pot life of 50 minutes; pour the first half of the mold in a long, thin stream to avoid air bubbles. Allow this first half of the mold to cure for 4 hours.
