Step 1: Step 1: Preparing Mold for Resin Casting

First take pearlescent powder and apply it with a soft brush onto the surface of a silicone mold. Thoroughly coat all surfaces of the mold. Pay particular attention to deep detail and the mold side walls. Remove any excess powder by gently tapping the inverted mold.

Step 2: Step 2: Dispensing, Mixing, and Casting Resin

Carefully measure out part B of the resin, then pour it into the mixing container. Add a few drops of urethane tint to Part B and thoroughly mix. Now carefully measure out part A of the resin, pour it into the mixing container and mix with Part B.

Carefully pour the mixed resin into a single spot in the mold. Allow the material to slowly flow around the mold, completely filling the mold cavity. Allow the resin to cure fully.

Step 3: Step 3: Finishing Piece

Once cured, remove the casting from the mold.

Many different effects are possible with this technique.
