Thank you PE
I ordered photogelatine at Fotoimpex already, prompt delivery. IŽll phone Mirko about the raw chemicals since their e mail reaction to my question was negativ.
Since Fotoimpex is an important retailer in Germany, IŽll report his reactions. Perhaps it would be better if Mirko posted a reaction himself. Could make an end to the uncertanties.

Thanks again,

Henk
