You can make a good, tried and true developer in two solutions as follows:

Pyro Solution, A

Take 1 ounce of pyrogallic acid, called pyro for short, dissolve it in 28 ounces of water and then add 20 minims of sulphuric acid.

Soda Solution, B

Dissolve 2 ounces of desiccated 48 carbonate of soda and 3 ounces of sulphite of soda in 28 ounces of water.

When you want to develop a plate mix 1/2 an ounce of the pyro solution and 1/2 an ounce of the soda solution with 4 ounces of water and to do this you need a graduated glass.

How to Make a Fixing Bath

To make a good fixing bath for dry plates dissolve 1 ounce of hypo, 60 grains of sulphite of soda in crystals and 1/4 ounce of borax in 20 ounces of water. A developer can only be used for one or two plates but you can fix 50 plates in the same fixing bath.

48 Desiccate means thoroughly dry.
