Why is resin casting more prone to bubbles than other materials?

Answer 1

Because it’s thick/sets fairly quickly so when stirring vigorously you are adding in oxygen bubbles.

When I work with resin I tap tap tap tap to encourage the bubbles up to the surface, obviously can be difficult depending on the shape you are working with, but that’s the trick I was taught in school !
