Thank you, Daniela and mshchem, I've been enjoying Foma 131, warming it with a shorter time in the developer [2min vs 3mins normally] and a slight time [30secs] in a weak [1:19] selenium. As you all probably know, 131 warms much more readily that ILWT, which I have printed a bit with, often finishing with a bleach/polysulfide toning [viradon].
