Kevin ordered a custom-made shaving soap brush in brown acrylic with acorn tops.
Here parts A and B warm up in hot water to make the viscous resin thinner, helping any air trapped within to rise. In the right cup, you can see the liquid colorant at the bottom and powdered colorant floating on top. It looks like a tiny amount, but both colorants are quite concentrated.
The resin is a 1:1 ratio. After pouring A into B, they get thoroughly mixed.
The mixed resin in poured into its prepared mold. The mold is made from card stock paper rolled into a tube just larger than the desired width. In the mold, you can see the acorn tops, carefully placed upside down to help keep them from trapping air.
Finally, the mold with resin goes into a pressure pot for several hours. The high air pressure helps reduce any air trapped in the resin to shrink to invisibility.
