lol! But apparently it was reduced in 2011:

> In 2011 Congress passed the Reduction of Lead in Drinking Water Act (RLDWA) revising the definition of lead free by lowering the maximum lead content of the wetted surfaces of plumbing products (such as pipes, pipe fittings, plumbing fittings and fixtures) from 8% to a weighted average of 0.25% [https://www.epa.gov/dwstandardsregulations/use-lead-free-pip...]

Given the median water pipes in many cities are 75+ years old, it's going to take a pretty long time for the new regulation to have much effect.

For a long time thorium oxide (99 percent ThO₂ and 1% cerium(IV) oxide) was used to make some mantles in portable camping lanterns. https://en.wikipedia.org/wiki/Gas_mantle#Safety_concerns

I remember as a kid wondering how that mantle - which looked like cloth - could glow without disintegrating. Worse yet - break one of those mantles, then breathe in a particle ...

EDIT: Looks like Coleman switched to Yttrium...

lead-free means lead comes free.

No, it just means the lead is free as in freedom, distributed under an free license.

No, thats lead-gratis
