Fellow Silverados...
Does anyone know what the purpose of Paraformaldehyde is in lith developers?
It is to promote infectious development.
Hydrazine is also used, but I do not know about substituting one for the
other. Probably the entire formula would need modification.
If Acetone can be substituted, what is the ration of the substitution?
How does Acetone compare to Paraformaldehyde in the resulting print?
Thank you in advance.
