foma emulsion / bromoil
(Emil Gandolfi in particular)
I bought Foma emulsion in 1 kg bottle, coatet 5-6 watercolor papers.
so far no problems.
two weeks later the emulsion has stiffened in the black bottle, need a spoon to get it out.
no hardener added, kept airtight and dark in 18 degre C.
after heating the stiffened stuff up to 40 degree C it is liquid as normally.
emulsion expires april 2014.
i have not yet developed any, will it work ?
have you seen this before?
is it a bad batch ?
will diluting with water be any good ?
i am a bit worried as i bought 2x1 kg, now kept in refrigerator.
