Farmer's reducer, as traditionally "home made":
Stock solution A = 5 % sodium thiosulphate
Stock solution B = 2.5 % pottassium hexacyoanoferrate(III)
Both solutions are stable
For use mix 4 parts of A with 1 part of B. This mixture will deteriate quite
quickly, so make fresh and use immediately.
If the reducer is too strong, dilute with distilled water.
