Really? Freeform Clay & Supply in San Diego sells it. Not saying it
isn't so, but it seems to be readily available.
I was there this afternoon to pick up some other items and noticed
several bottles and bags clearly labelled as lead glazes. There were
no signs anywhere saying that a license was required to buy any of it.
I've actually discussed this with one of the owners of the business
as one of his big customers uses a lot for various tiles he
manufactures. He did say it is not possible to get it as red or white
lead, but it is available in frit form. He never mentioned any
restrictions on buying it either, just that it was illegal to use it
on items to be sold for food service. While I may not have gotten the
whole story, I would hope he would know what is required by law.

Now I never stated that it was definitively a lead glaze. It's
possible it may have come across that way but I never intended it to
be anything but a cautionary statement (which has been passed on).
What I did say was that to the best of my knowledge (which I know is
not complete as I am not an expert), it could be a lead glaze as it
looks very much like some lead glazed items I have seen (particularly
a lot of Mexican bean pots). I felt it was better to raise the red
flag just in case. Better safe than sorry.
I am curious what Hroar has to say if he has had a look at the
photos. There seems to be a certain clarity and reflective and
refractive quality to the lead glazes I have seen that just does not
seem to occur in other types. But again, I am no expert and can only
go by what I have seen so far.
>Hroar isn't positive how easy it is to get lead in Europe, but there

Under current EU laws, it's nigh on impossible to get lead for
anything. The Resolution on Hazardous Substances aka RoHS makes the
use of lead in any application other than a very few where it is the
only option pretty much illegal. This limits its use to mainly car
batteries in any of the EU states. I've been dealing with this
particular issue in the electronics world for several years as any
commercial products must be made using lead-free solder. The only
exemptions are for certain military and high-reliability applications.
Now having said that, The Republic of Macedonia is not an EU member
state and it is completely unknown to me what their laws regarding
the use of lead are. Knowing that, I suggested caution. They may well
be following the EU guidelines but I have a real tendency to doubt it
with the breakup of Yugoslavia causing so much chaos for so long.
Now we don't know if the pot was made in the Greek region known as
Macedonia where EU laws definitely do apply or in the former Yugoslav
nation. Lacking that knowledge, it is again better to be cautious.
As for worldwide education on the dangers of lead, that is definitely
a good thing, but there are also countries out there who have proven
they simply don't care. How many times in the past couple of years
have we heard about lead paints and other contamination of toys and
consumer products from China?
>But you are correct in that it is better to be safe than sorry and
>using a lead test kit on the piece is wise.
Exactly my entire point, and we all seem to agree on that one.
