The same "properties" for the same "pigment" is by no means a foregone
conclusion when buying tube paint. In my experience manufacturer additives
can make a fine pigment unprintable... as for instance what I assume to be
dispersal agents added in some brands to some colors, which can make heavy
stainers...
I've never found a dry pigment unusable... I haven't tried that many and
don't like dry pigment for other reasons, but suspect that the additives
could be what make some tube paints bad -- or good. Thickeners,
emulsifiers, dispersal agents, non-compatible gums... & so forth, which
are NOT listed on the label, or elsewhere that I know of.
