Carefully measure out Smooth-Cast® 300 resin, Part B, then pour it into the mixing container. Add a few drops of So-Strong® Black tint to Part B and thoroughly mix. Now carefully measure out Smooth-Cast® 300 resin, Part A, and pour it into the mixing container and mix with Part B.
Carefully pour the mixed Smooth-Cast® 300 resin into a single spot in the mold. Allow the material to slowly flow around the mold, completely filling the mold cavity. Allow the Smooth-Cast® 300 resin to cure for a minimum of 20 minutes.
