Just ordered chemicals to use for SLIMT

I won't, safety is number 1 priority. It is a speedwise bleach for pull processing according to Kachel's write up on bleaching.

Hm, I'll have to read some more of Kachel's writings. I wonder why he would choose a dichromate process despite its obvious drawbacks (toxicity, stain).

This is all new to me. Just trying to find a solution to the challenge of shots I like to make.

So, following the mixing instructions for just the Potassium Ferricyanide to get a feel for the dilution strength, I followed Kachel's recommended formula for a starting working solution and came up with a mixture taht of .45gms PF to 450ml of water (if I wanted to mix it every time I used it. Of course I would still need to figure the amount of Potassium Bromide to prevent fogging) In reality though, I will just mix the Full strength Stock solution as he recommends, then from there the stock solution which then becomes the working solution where you play with the dilution to get what you want prior to adjusting times to fine tune. I am surprised at how little Potassium Ferricyanide is actually used in this process. Wish developer was as cost effective

I am going to be using Tmax100 and HP5400 to start with. Has anyone used this technique with those films? My developers are listed above.

My tripple beam balance will be here this week I hope. Good thing I paid attention in my college chemistry class!
