My resin has become solid inside the container. How can I make it liquid again?
Cooler temperatures can cause the epoxy resin to become solid due to the high bio-content. Carefully submerge the lower half of the tightly closed container of epoxy in warm water until epoxy returns to a liquid state. Placing the container in a warm room is slower, but will also work.
