Those proverbial "Men in Black" would be at your doorstep rather quickly. Photographic chemicals are rather benign, but don't lick any spoons that are left unattended. If you are mixing the divided D-76, there is an improvement on the original formula, cut the sodium sulphite in 1/2. Use 50 gr/ 1000 ml rather than 100 grams. This gives you a slightly tighter grain ( on Tri-X at least) and it doesn't require any significant extension of the times. Sod. Sulphite is a silver solvent and the 100 gram/1000 ml tends to make the grain a bit mushy. Well, as they said in the 60's " Happiness through chemistry" and it still works, at least when it comes to filmprocessing!! Tom A
