Hello everybody,
I got very helpful answers from you guys last time, so I decided to ask again

In my infusion process I use low viscosity infusion resin. When I try to degas it with my home-made chamber I get many bubbles escaping from my pot and forming a big foam on the surface. This is endless

I use full power of my vacuum pump (nearly -1.0). I've never managed to get clear liquid after degassing.
What should I do to improve it and make it more effective?
