The burnt umber won't completely "dissolve." They just get *dispersed* in
the emulsion. The particle itself is very finely ground, so you shouldn't
see any lumps. If you are, they are not the pigment itself but clumps of
pigment + acrylic binder. I think when you mix it, you probably added too
much liquid the first time. Just try to add a few drops of liquid to the
pigment, stir it until completely mixed in, then add a few more drops and
repeat until the mix turn from pastely into creamny. Then you can start to
add a little more liquid each time.

This is hard to describe in words. Are you into cooking? The situation is
like when you mix flour with water, they tell you to add just a little water
at first. Otherwise you would be pushing the clumps around and it is very
difficult to get a good mix. If you add just a little water each time, then
it will be easier to mix. The other situation is like mixing cocoa powder
into milk. The cocoa powder doesn't dissolve in the milk either, so you have
to disperse them.
