casting with hide glue - shrinkage
I want to do a cast in hide glue. The mixture I am making now - 1:1 hide glue cake to water - dries within 2 weeks. It shrinks. What can I do to minimize shrinkage? I'm trying talc and wondering if you have any other ideas. Also, I have lots of bubbles. I want to invest in a vacuum chamber. Will it degass this water based mix of hide glue?
