[Ansteorra] Pottery questions ad absurdum (was: question for potters)

[Sir Lyonel Oliver Grace]

Salut cozyns,

Sorry, I don't buy it.

First, Torquil and--everyone else involved in this thread--needs to drop all 
discussion of lead glazes. No one asked about lead glazes. We all know 
they're dangerous, but that has nothing to do with the chemical make-up of 
clay.

Second, I'd like to see a reference supporting Torquil's claim that, "all 
clay has lead in it if it has been mined from the earth." Even if I believed 
this (I don't--lead is not ubiquitous), I'd want to see evidence that said 
lead content was high enough to be a health concern.

Third--and here's where all this claptrap about glazes has become such a 
distraction--Torquil claims that

>Bisqued pottery (fired) still has lead in it enough to exceed the fda and
>epa standards and over time can make you ill, that is why they (the
>Goverment) required lead free glazes in products to be used for food 
><snipped run-on>

No. Absolutely 100% wrong. The requirement for lead free glazes to be used 
for food is to eliminate the lead from the glazes not to block lead 
absorption from the clay.
