noacronym - I know not your understanding of paper types, so forgive if this is a known thing to you, but Slavich Unibrom 160BP is graded Bromide paper. In the US there are only two Bromide papers avail 1) Slavich unibrom 160BP and 2) Kentmere Bromide. However, Kenmere is only avail in grade 3 glossy double weight, while Slavich is avail in single/double and matte and glossy and avail in grades 2,3,4. For the printing I most enjoy (inspired by the great work of Thomas), I find matte works best for me. Though I love a real cold, almost blue/black matte. That led me down the path of Slavich. After seeing some of the work that Andy Maxom, Mark Fisher, VaraV and Max Marinucci have done with Slavich I was sold. It is a great paper, receptive to toning, though I only tone in gold thus far.
brianmquinn - I use Liquidol, I mix it a bit hard too, it is normally 1:9 (eg 100ml to 900 ml for a L), but I do a bit more strong, which gives even better, deeper black (143ml Liquold to 857ml water to make 1L). But I figure Dektol or any other neutral tone dev would yield the same deep black, maybe it would really get deep blacks if one mixed it even more heavy like I do with Liquidol, but I have not done any other paper dev, so I am not too sure.
Thomas - I will have to give it a try, though I don't see myself doing that anytime soon, I've a long list of negs needing printing that I am going to print cold and then tone in gold (T-26). But Ive a pack of Kodak Sepia burning a hole in my darkroom drawer that I should mix up for you. Thanks for all your discussions re matte paper, it really has me thrilled!
