2. Add silicone pigment paste

The video specifies silicone pigment paste at 0.4–0.6% by weight for this project. This is the amount documented in this process, not a universal recommendation for every silicone system. Follow the specifications for the silicone and pigment you are using.

5. Make the second silicone pour

A second silicone pour follows. Keeping the two pours separate in the process description makes the order of operations clear; no waiting interval between them is specified here.

6. Demold the silicone mold

The final stage shown is silicone mold demolding. A curing duration is not specified in this article; use the curing requirements of the actual silicone system rather than borrowing a time from another project.
