Air, moisture, and speed create most problems. Warm resin and hardener to room temperature, then mix slowly to avoid whipping bubbles. Degas with a brief torch or heat gun after pouring, using quick passes rather than holding heat in one spot. Seal porous inclusions first, since trapped air releases later and causes bubbles. For clouding, avoid overmixing pigments and keep humidity low during cure. To prevent edge crawl on glass, clean with alcohol, avoid silicone contamination, and let resin find the edge before coaxing it. Cover the piece to block dust and give it time to level beautifully and cure.
