How can we reduce bubbles in plaster? In this video I try 3 different things. The first is windex on my silicone mold. This is supposed to help with surface bubbles and seems rather effective! The second is a different type of mixer for the plaster. This one doesnt move the plaster up or down pulling in air and instead slings it out to the side. I think this also helped. Finally I found an old industrial shaker table and try it out. The ideas is as it shakes the bubbles will rise to the surface. It also seemed to help. However! I still had bubbles, but only under horizontal surfaces. So I think my silicone mold is capturing them and preventing them from escaping. This will like require redesigning my molds in the future.
