As the chemical analysis of local frits are not available & several
attempts to have them tested locally have failed (the boron & lead seem
to distort the results), please can a fellow Clayarter tell me where to
have them tested either in the USA or UK.
I will have to post the samples & be able to pay by credit card or paypal.
Many thanks

Tracey,
I have used the company ALS Chemex and was satisfied with their work.
They have an office in Reno Nevada for the mining industry, and other
offices around the world. I had them do X-ray florescence (XRF)
testing on my local minerals.

In fact, when looking at the website above, I saw they have an office
in Johannesburg South Africa.
Good luck getting your frit analysis.
