from "What you want to Know About Developers by Dr. Edmund Lowe on Pg. 99.(posted 8206 days ago)Water.........................1 liter Para-aminophenol(base)......3.5 grams Sodium Sulfite.............. 90 grams Sodium Sulphate .............40 grams
no time are given, but the developer can be used up to 90 degress F.. 70 degress is recommended and you have to increase the time by 5% for each roll.
If you convert the Aminophenol to the sulfate, you then have GRADOL. Which is used in Edwal's Super 20 formula.
