The following is the response I received back from Sax's "paint
specialist"........
I, too, have had trouble with tempera separating (and going sour) on me.
Once the binder deteriorates it's hard to make it work again. I think
pouring of the liquid from the top and using the pigment on the bottom in an
acrylic medium is the best idea.
I know that this idea had been posted already......just wanted to share that
our "specialist" concurs!

Subject: tempera paint
A previous teacher had purchased large quantities of liquid tempera paint
that are now separated in the (unopened) bottles. It appears to be flakes
suspended in whatever liquid they used. I have tried several methods of
getting it unseparated, but so far have had no luck. I've tried shaking it
and stirring until my arms were too tired, and I also tried heating some of
it. At best I've managed to get the flakes somewhat smaller and more
dispersed. Does anyone have suggestions to revive the paint?
