Talking Lead Analysis Data Summary

The "lead content" being functionally zero in all of our colors, with the exception of Gaia, an older color made using Italian cullet as an ingredient. Gaia, which tested at 475 ug/g, is the only color that did not qualify as "Lead Free". The CPSIA permissible limit for lead content is 300 ug/g (PPM). Gaia is made using Italian Emerald Green 591030.
A 2012 new release production color, Oxalis (OX-380), has been formulated from scratch to offer an alternative to Gaia, with zero lead content, stronger luster effects, and an unusual green tone not found in commercial glasses. Oxalis will be available later in the year.

We also do not use Nickel, Cadmium, Selenium, Arsenic, Antimony, or Chromium in any of our production colors.

Some Lead Crystals use up to 65% Lead Oxide as batch ingredients. I'm not sure how that translates into PPM in finished glassware, but it must be a bunch.

Here's a LINK to the CPSIA website for those who are interested.

Thanks,
