>>today ifind an interesting book with a lot of formula:
copper, lead, mercury, manganese papers
and picture on zinc plate.

I have seen examples of similar techniques; there are more than 10,000
published formulas for sensitizers. I must point out that some of them hold
potential for disaster - mercury based emulsions and sensitizers for
example. Do your research carefully before trying these techniques.
