This product is advertised as lead-free. (See related post here.)
The bottle is primarily made of stainless steel. All components that touch the contents are lead free.
The center sealing dot (on the bottom of the outside of the bottle), the element that seals it so it is an insulated bottle, is made of lead and is fully exposed/has no protective coating. (Scroll down to see pics so you can see exactly what I mean.)
When tested with an XRF instrument this sealing dot tested positive for lead in the range of 597,000 ppm Lead (+/- 4,000 ppm.) As a result, in spite of their advertising claims, this bottle is not lead-free.
As always, thank you for reading my posts and sharing my links.
