Get a copy of "Use of home test kits for detection of lead and cadmium in
ceramic dinnerware," Ralph W. Sheets, The Science of the Total Environment,
219(1998) 13-19. Ralph already compared the efficiency of the kits. I
believe the kits failed to detect lead about 10% of the time at the FDA
level. And they did really badly on cadmium.
I recommend the kits for positive identification. But a negative test should
not be considered proof there is no problem.
