When is the right time to add my pigments?

Many artisans and crafters choose casting resin for encapsulation - so they prefer crystal-clear material. However, casting resin may be easily colored with a variety of pigments, dyes and tints. After mixing epoxy and hardener in a 2:1 ratio for 5 min., add pigmentation into mix, and stir thoroughly for another 3 min before pouring.
