Today I was in a hurry and grabbed a dicromate bleach instead of ferricyanide-bromide bleach for toning with thiourea. Dicromate bleach is used for Bromoil preparation and hardens the gelatin slightly.
The images bleached ok and had the usual tan/greenish gelatin that the dicromate leaves behind. I did not fix so did not lose any silver.
washed bleached prints for 15miutes.
I mixed my Toner at 10ml Thiourea, 40ml SH, 500ml water trying for a deeper brown than sepia yellow-brown. Toned for about 1-2 minutes depending on amount of shadow area.
The images have a nice chocolate tone on multiple papers souped in two different developers. The only side effect I can see is that the white borders are purple-ish on the warmtone papers.
I am not seeing much of a color difference between the different papers: Ilford Art, MGFB Classic, MGFB WarmTone, and Bergger CB VC WarmTone. Developers were LPD or PF106.
