Greetings-

Bob Szabo asked me-

>Do you also have a formula the bleach bath? I would like to mix my own.

I thought I'd CC it to the list.

Again, this formula is from the Eddie Ephram's book, "Creative Elements."

One liter "Standard Toner Bleach" STOCK solution-

750 ml water at 40*f
100 grams Pot Ferricyanide
100 grams Pot Bromide
Water to make one liter

Work Solution-

One part bleach to 9 water (OK to increase ratio for faster results)

* For colder image tone, use 1/2 the Pot Bromide. For warmer tones
increase Pot Bromide to 150 grams, or more.

Note: Ephram's also lists two alternate bleach options-

* Colder tone bleach (use undiluted)-

750 ml water @ 40*F
6 grams Pot Ferricyanide
15 ml of 10% ammonia
water to make one liter

* Warmer tone bleach

750 ml water @ 40*F
6.6 grams sodium chloride
35 grams Pot Ferricyanide
Water to make one liter

Good luck.

Best-
