Walter - could you post a typical mixture that produced this effect ?
It sounds so different from anything you've done before.
Also any chance of a photo
Rancherbill - Hi Bill. I suspect that the "de-airing agents" that Cameron has mentioned might be something along the lines of a surfactant. I'm only familiar with their use in water based systems, but I'm sure there must be other, non-aqueous ones.
I think someone touched on the loudspeaker idea before. I can see that any vibrational energy source might be used. The difficulty lies in designing it to "couple" the energy to the mixture.

It's like doing jigsaw puzzles in the dark.
Enjoy today's problems, for tomorrow's may be worse.
