[pure-silver] Re: Viradon - cooling print tones!?

Both Richard and Tim responded similarly. My confusion is that it was a
combination of Agfa Multicontrast Classic and the latest Viradon. These same
materials were producing varying degrees of warm tone, from a tint to a deep
chestnut when I used it during the summer. I can only think it is the
temperature...or it has occurred it may be the duration of the Sodium
Biwhatitsname stopbath....
This coming holiday I will have to do something more scientific.
