Re: Taming Fabriano Artistico (Trad. White) for Cyanotype
Loris, Since you are diluting the acid anyway, is there any compelling reason you are using HCl and not some other more benign acid? I really like the results I'm getting putting gum on plywood and aluminum but I could use some more dmax. Cyanotype doesn't work. Am I to assume that the alkaline nature of the the gesso is incompatible with the cyanotype? Would there be any point in trying to acidify the surface? 2008/12/3 Loris Medici <mail@loris.medici.name>: > 3 Aralık 2008, Çarşamba, 11:22 am tarihinde, Loris Medici yazmış: >> ... >> Conclusion: HCl treated Fabriano Artistico TW is OK / fine for Trad. >> Cyanotype.
