[pure-silver] Re: Old Paper Developer Question

I found that it was available at Alfa-Aeser (sp?). It was expensive, and the cost of sending it to Australia was prohibitive.
I have Brovira from the 1970s that is still good: no fog in standard developer, but Portriga-Rapid from the late 1970s was very badly fogged. I don't think a different developer would have helped in this case. An enexposed sheet developed in my standard warm tone developer looked like a brilliant sunset.

I have had good sucses with adding benzotriazole to the developper. It
seems there is a developper that is supposed to give fog free prints on
outdated paper. It contains chlorohydroquinone, it's called Defender
58-D, :

Defender 58-D
Water 750ml
Sodium Sulfite 16.0grams
Chlor-hydroquinone 4.0grams
Sodium Carbonate 16.0Grams
Potassium Bromide 0.6grams
Water to make 1Liter

I have not tried it myself (yet)

Best,
