Fired gold luster is not usually fluxed with lead...when fired it is usually about 20 to 22 karat gold. So that should not be an issue. And the amount of surface area actually covered by that material is usually VERY minimal anyway.

Thanks for your answer, John.

After reading the PDF and doing some research, it is certainly worrying the aspect of the presence of lead, almost everywhere around us.

Allow me a question, although it is not directly related to teaware but to an important issue of which teaware could be a part: Do you know if there are effective chelating natural elements?

Best Regards

Good evening Collector

I am not a expert, but I would imagine, that Tea may be an effective
chelating substance.
Simply speaking, a chelating agent "disarms" free radicals (nasty critters) by locking them up (in larger molecules). I hope I am not treading on too many liberal toes ;-) - but is this not precisely what tea is supposed to do?

I never really thought of tea being basically 'republican', I do know however, that some sort of mould was named after Mr. Rumsfeld - perhaps
it would improve some of my spoilt (cheap) puerhs ....

Adieu for now

collector,

I can speak reasonably well on issues of ceramic toxicology and the technical side of ceramic process. As to making treatment suggestions or recommendations.......

That would get into practicing medicine without a license. :wink:

I really do not know much about chellation therapy. I'd suggest consulting a medical professional about such matters. With something as significant as lead poisoning, treatment should be taken very seriously and you should become very well informed about it. (Remember there a "quacks" out there that can cure everything and that just love to take your money.)

best,

Totally agreed. In fact, I've passed up some very interesting pieces for just that reason. It would annoy me too much not to be able to drink out of them without worrying.
So, from your post I should understand that cold be safe to drink from not internally painted ware?

What about the safety in white and blue coalport, derby HC & A bouquet etc?

I certainly am not technically trained, and unless I want to test everything before using (cannot before buying), I paint this rule with a broad stroke as a result. Some common sense and "general" info found here on TC is all most of us can go by.

19th C. Transfer Export are interesting. A full set of transfer English, French, or Dutch are more interesting. 10 to 12 pieces per item, 12 to 20 items per set.
