I am very puzzled by what could be in this developer that
separates. AFAIK, the ingredients go into solution. Once in
solution just gravity should not separate them. Developers
are not like milk, which is not a solution but an emulsion.
If subject to low temperatures its possible that something
crystalizes but should go right back into solution once
warmed up again.
