Hey All,

A couple of years ago I saw an article about testing glazes for leaching either in Clay Times or Ceramics Monthly.
Since I worked at an art center at the time I wanted to test the class glazes and make sure none of them were
dangerous but when I tried to find the article again, naturally I couldn't find it. How does one go about testing for
leaching?
