Overheating the resin in the mold or using a heat gun too close can degrade the silicone. Clean with mild soap and cool water, and store flat. Replace mol...

Some epoxy resins are UV-resistant, but most yellow over time outdoors. Use a topcoat with UV protection or choose a resin formulated for outdoor use.

Epoxy resin generates heat as it cures (exothermic reaction). Large volumes cure faster and heat more—this can lead to premature gelling or cracking. Mix...
