Looking for a paper developer, phenidone/vitC/Borax
Years ago I saw a formula, here in Apug I think, of a paper developer using phenidone, vitC and borax, without carbonate, but I'm not able to find it now, neither here or elsewhere, probably from Gainer, but not sure.
Does anyone knows about it?
The matter is that I've run out of some raw chemicals, mainly MQ and Carbonate, have some prints to do and restocking isn't possible in a few days, so I'm looking for a decent emergency replacement. Tried E72 but without carbonate blacks are weak.
Thanks in advance.
