To All Clayart Members,
There is now a second source for having your glazes leach tested. With
the gradual building of volume in the testing arena, I felt it would be
good practice to have a second source. Also I have always been one to
believe in healthy competition. So I went to a lab near me and talked to
them about it. They were interested and I have been working with them
for 3-4 months now. At one point I sent a duplicate set of 7 samples to
them and to Alfred Analytical and they came back virtually the same.
The bottom line is that I can now recommend Brandywine Science Center,
Inc. (BSC) as an excellent place to have glazes tested--as nearly as I
can tell equal to Alfred Analytical. Their price structure is different,
but competitive--$5 for the leaching and $13 for each metal analyzed for
(except lead which is $18). So 1 sample analyzing for 1 thing costs $18;
1 sample analyzed for 2 things cost $31. That is vs. $20 and $30
respectively for Alfred Analytical. They also take VISA/MC which might
make dealing with them easier for those outside the U.S. Both labs
charge extra to return samples; if you want yours returned contact them
directly to determine the cost.
Service is at least as good at BSC (for me it has actually been better).
Usual disclaimers apply. I have no financial interest in either BSC or
Alfred Analytical. I am still testing quite a bit and will continue to
use both labs.
To discuss their service ask for Mike at BSC. Their address is:

My web site has also been updated to reflect the availability of BSC as a
testing source.
