Silicone mold for casting a sphere 20-100mm

Two-piece suits can be nerve-wracking, we know.
For easier use, we recommend:

1. pour the full lower part first
2. make the edge together with the same resin
3. place the upper part on top
4. wait until the first part hardens and the form becomes “waterproof”
5. after the first part, pour the upper part full of stone.

Or carefully and tightly cover the joint of the already assembled form with hot glue, which is a faster and somewhat more reasonable option. Later, the strip of hot glue will come off the mold beautifully as a whole ring and should not leave any marks.

You should definitely not connect the different parts of the mold with a silicone-based sealant or mastic, this will most likely result in a “one-off” broken mold.

When filling a half mold, you should not use a fire to remove bubbles, but a heat gun.

When removing the mold later, it’s a good idea to do it in soapy water, it helps the process a lot!

As always, the less damage the form receives in the form of scratches and breaks, the longer it will last.
