This is an uncoated Stainless Steel Corkcicle brand water bottle (pictured above).

This product is expressly advertised as Lead-free. (See related article here).

The bottle is primarily made of stainless steel — without paint, embellishment or adornment. While all components that touch the contents are Lead-free, there is a fully accessible component of this bottle that tested positive for a very high level of Lead.

The center “sealing dot” (on the bottom of the outside of the bottle), the element that seals the two layers of Stainless Steel so the bottle has the insulative qualities required to keep beverages cold (or hot), is made of melted Lead (possibly 60/40 Lead solder, which is 60% Lead — or 600,000 ppm Lead). On this particular bottle, the Lead is fully exposed/ has no protective paint, coating, cap, or cover. Please scroll down to see photographs of this area 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 Corkcicle’s advertising claims, this bottle is decidedly not Lead-free — in fact, it has a dangerous amount of Lead in an area that may be frequently touched by the user.

Please read this article for context.
