Yesterday evening I mixed from scratch a new badges D-76H developer. Not ever mixed before this type. It seems a piece of cake to me because I mix my own Pyrocat HD from scrtach to. Never sorted any problem. I weight carefully the ingrediënt and mixed them in water. This afternoon I made a test with a piece of film to check if the developer is active. There was no reaction even the film markings of the manufacturer didn't appear. So I was wondering where this problems come from. The ingredients I used are: Metol, 2g - M=334,39 g/mol - CAS 55-55-0 Natriumsulfiet, 100g - M=126,04g/mol - CAS 7757-83-7 Borax 2g - M=201,22 g/mol - CAS 1330-43-4 These data where found on the labels of the chems. We do have here one of the best waterqualities in the world and have never experienced any problem with it. I'am not a chemist realy, I only follow the descriptions as mentioned in de the Film Developing - and Darkroom Cookbook. What did I do wrong? Thanks.
