Allan, I'm really wishing there was a way to send you white lead pigment. I'm sure before long, it will become unavailable in the USA too, so looking ahead, I bought a sizeable quantity, and I feel like some kind of miser. I'd gladly share with you, if I could just send it without red-tape. With all the concerns of terrorism and drug trafficking, it surely wouldn't do to tempt the authorities with contraband pigments!! (Honest, officer . . . it's not cocaine . . . too heavy! See? - Hey! Put down that gun!)
It just occurred to me that depending on what you're using for a source of lead to make your own might not be pure lead ? For example, automobile wheel weights and fishing sinkers are usually alloyed with some zinc, sometimes tin and antimony too. I don't know how that would affect the reaction.
Do you happen to know the wherefore of the reaction that results in lead carbonate? Reaction with the acetic acid in vinegar will make lead acetate, I'm sure . . . yet this is how the "old masters" did it . . .
