This is from an exchange I had with Douglas Nishimura at RIT in June of 1997:
GP-2 formula:
Water - 750 cc
Gold Chloride [a] (assay 50% AU) - .50 gram
Tartaric Acid - 1.0 gram
Kodak thiourea [B] - 5.0 gram
water to make - 1.00 liter
This is excerpted from a four page letter Douglas sent to me - it is,
unfortunately, no longer on the computer's hard drive. This letter is full
of details regarding replenishers, hardeners and rates of depletion etc etc
- a wealth of information. I will make copies of my print out and mail it
to you if you wish to see the entire missive - I'm no hand at typing....
Hope this helps.
Best - Jon
