Mountain Rose Herbs Brown Glass 4 oz Bottle: 112 +/- 17 ppm Lead (considered safe by all standards.)

When tested with an XRF instrument the brown glass of this Mountain Rose Herbs bottle had the following readings (these readings are typical for brown glass & you can see more examples HERE.) If a metal is not noted in the result set below it was not detectable by the XRF in the particular test done.

Reading #1 (on side of bottle)
(each reading done for a minimum of 60 seconds, with a freshly calibrated instrument)

• Lead (Pb): 80 +/- 13 ppm
• Barium (Ba): 18,500 +/- 400 ppm
• Iron (Fe): 2,153 +/- 120 ppm
• Bismuth (Bi): 21 +/- 12 ppm

Reading #2 (on side of bottle)

• Lead (Pb): 81 +/- 13 ppm
• Barium (Ba): 16,700 +/- 400 ppm
• Chromium (Cr): 186 +/- 117 ppm
• Iron (Fe): 2,199 +/- 119 ppm

Reading #3 (on rounded edge of top of bottle)

• Lead (Pb): 112 +/- 17 ppm
• Barium (Ba): 2,061 +/- 89 ppm
• Zinc (Zn): 47 +/- 19 ppm
• Iron (Fe): 3,531 +/- 280 ppm
• Bismuth (Bi): 24 +/- 11 ppm
• Vanadium (V): 822 +/- 70 ppm
• Titanium (Ti): 1,714 +/- 123 ppm

It is possible to have Lead-free brown glass – here’s a link to a good example of that.

This low level of Lead is probably/possibly not leaching from the bottle under normal circumstances, however I don’t know that the specific concern has been studied when looking at contents including citrus based essential oils.

In my opinion I think the concern merits further study and in the absence of further study it would be great to see these companies switch to Lead-free colored glass alternatives which is consistent with their overall stand about health and the environment. [I understand – from talking to folks who sell these products – that the color of the glass is important to protect the contents from deterioration with exposure to light.]
