I have wanted to try the Agfa 120 formula for quite some time but don't have all the ingredients -- so -- experiment,
I only made a 250ml batch as I didn't want to waste chemistry.
The main ingredient I was missing was the Potassium Carbonate.
Water 200ml
15gms Sodium Sulphite
6gms Hydroquinone
6gms Potassium Hydroxide
[Read up on safety issues when handling Hydroxides]
***** Gloves and eye protection are sensible.
.5gm Potassium Bromide
Water to make up to 250ml
Use at 1:4 for warm brown black.
Exposure will be about double.
I don't know the keeping life of the chemistry.
The paper I used was Ilford matt MG FB. I also have some Foma so when I'm next in the dark I will try that as well.
Also meant to mention that the resuls are very pleasing.
