4. Allow the encapsulator material to fully cure inside the mold. You might want to accelerate the cure by applying heat. As a rough guide, the recommended cure schedule for a l-inch-thick Ultracal mold is 2 to 3 hours at 200°F (93°C).
5. Allow the mold to cool.
6. Mix the gel components together and add pigment and/or flocking, then de-air them in an evacuator (vacuum chamber); or simply let the air bubbles rise and disperse on their own (only if you're using a slow-cure gel) . Fill the syringe with the gel and slowly inject it through one of the holes until it begins to come out the second hole.
