I am a beginner, and have tried several times to submerge polymer clay figures into resin sphere molds (clear silicone mold). Before I put the sphere under the light, I see absolutely no air bubbles, even using a light I cannot see bubbles. I do use a flame to bring bubbles out sometimes. However, when I take my project out of the mold after curing, there are tons of bubbles, and with my last attempt I literally watched as bubbles appeared seemingly
Out of nowhere under the light and even after I take it out, they still are forming. I have wasted so much time and resin and it keeps happening consistently. I am using a 36 watt UV bulb light. Flat keychains cure fine, it is the spheres that are giving me trouble. Could it be the polymer clay emitting gas somehow? I am so frustrated and any advice would be greatly appreciated. Thank you.
