This bottle was tested at the request of Lead Safe Mama readers. It tested non-detect for most of the common metallic toxicants we look for (there were no detectable levels of Lead, Arsenic, or Mercury in any of the four glass, plastic, and silicone components of this bottle)!
We did find trace (very low) levels of Cadmium and Antimony in several tests done on both the glass of the bottle and the silicone of the nipple. While not ideal, this is a common finding — and the levels found are considered safe by all standards. The implications of these findings are discussed in detail below (in red) in the section of this article with the test results.
Please understand the following important points in reading this, and other similar articles here:
- We do not recommend many products.
- If there is an article about a product on this website (any product), readers need to understand that that fact alone should not be misconstrued as implying any sort of endorsement or recommendation of the product — it is simply a write-up of the test results for that product, with a discussion of the implications of those test results if metallic toxicants (poisonous “heavy metals”) are found.
- We are working on reporting XRF test results for as many baby bottles currently on the market as we have the opportunity to test — this way parents and other caregivers can review (and compare) the metals profile for each component of every bottle we have tested in order to make informed decisions for their children.
- We hope you will review the various choices along with the test results of those products and make an informed choice of which product(s) to use for your own child. Please do not ask us to make that choice for you.
- If we find unsafe and illegal levels of heavy metals in any child feeding product, we will clearly articulate those findings and we will recommend not using that product (plus, as time permits, we will also report a violation to the Consumer Product Safety Commission).
- We are linking each of these baby bottle testing reports on various bottles to the Lead Safe Mama Baby Bottle Guide, which can be found at this link. (If you need to reference this Baby Bottle Guide in the future, it can also be found in the header menu at the top of every page on the Lead Safe Mama website.)
We began this project as an advocacy initiative after finding more than a dozen newly-manufactured baby bottles and other infant and children’s feeding products (manufactured and sold in 2023 or in the past five years) with unsafe levels of Lead — either in the form of Lead-painted measurement markings and decorations in the exterior paint on the glass, or in the form of other components that are high in Lead (for example the high-Lead “sealing dots” used to create the vacuum seal on many insulated stainless steel products, including insulated stainless steel baby bottles and sippy cups).
Please scroll down to read the full test results for the bottle pictured. There were five separate “components” of this bottle (including painted and unpainted glass — each tested separately) and all were tested multiple times to confirm any test results we have reported.
The recommendation of Lead Safe Mama, LLC — across the board, when it comes to baby bottles — is that the best bottle choice from a safety perspective (with respect to avoiding toxic heavy metals in children’s items, is an unpainted, undecorated plain glass bottle paired with a natural rubber nipple (assuming the child does not have an allergy to natural rubber, or any other issue with a natural rubber nipple).
- A second–best choice is a bottle with painted measurement markings or decorations that has been independently tested and has tested negative for toxicants in the paint, with a natural rubber nipple.
- Since a fed baby is best, if your baby is allergic to (or if your child refuses) natural rubber nipples, a third option as a good choice is an unpainted glass baby bottle with a silicone nipple.
- Please do be aware, however, that most silicone baby bottle nipples do test positive for traces of the heavy metal Cadmium, which is a known carcinogen. This trace-Cadmium found in baby bottle nipples to date has been, in all cases, levels that are considered safe by all current standards. Also important and relevant: silicone nipples should be swapped out for new nipples every four to six weeks (or if they start to get cloudy before then).
- If you have to choose between a glass baby bottle where there is trace-Cadmium in the glass (which is common), vs. one where there is trace-Cadmium in the nipple, trace-Cadmium in the glass is less concerning than trace-Cadmium in the nipple. In our experience, natural rubber nipples always test negative for Cadmium.
- Our baby bottle guide details which bottles have tested positive for traces of Cadmium (and in which component).
*Given the testing we have done to date, we have (to date) recommended this brand, this brand, or this brand of glass bottle — and then, if possible, swapping the nipple to a nipple made of natural rubber that fits the bottle you have chosen. Here is one example — and here’s a second example — of many possible natural rubber choices (although we have not confirmed these work well with the specific bottles mentioned).

Tamara Rubin is a multiple-federal-award-winning independent advocate for childhood Lead poisoning prevention and consumer goods safety, and a documentary filmmaker. She is also a mother of Lead-poisoned children (two of her sons were acutely Lead-poisoned in 2005). Since 2009, Tamara has been using XRF technology (a scientific method used by the U.S. Consumer Product Safety Commission) to test consumer goods for toxicants (specifically heavy metals — including Lead, Cadmium, Mercury, Antimony, and Arsenic). All test results reported on this website are science-based, accurate, and replicable. Items are tested multiple times to confirm the test results for each component tested.

Here’s a Lead Safe Mama, LLC affiliate link for this bottle.
Reading #1) Unpainted Area of Glass
180-Second (Three-Minute) Reading
- Lead (Pb): non-detect
- Cadmium (Cd): 19 +/- 3 ppm
- Iron (Fe): 169 +/- 49 ppm
- Copper (Cu): 18 +/- 11 ppm
- Zirconium (Zr): 793 +/- 11 ppm
- Niobium (Nb): 496 +/- 10 ppm
- Indium (In): 21 +/- 4 ppm
- Tin (Sn): 8 +/- 4 ppm
- Antimony (Sb): 20 +/- 6 ppm
- Platinum (Pt): 26 +/- 14 ppm
- No other metals were detected in consumer goods mode.
*Note: We tested the unpainted area of this particular glass bottle in several areas, and multiple times to confirm the presence of both Cadmium and Antimony. The Cadmium and Antimony (at the levels found) are trace contaminants of the glass and not — in any way — found at levels that would indicate they are added ingredients. I do not have a concern for the presence of trace Cadmium and Antimony in the glass of this bottle (especially at these very low levels); it is likely bound in the glass and non-leaching. The test result set noted above is one full test result set.
Reading #2) Painted Area of Glass — Black Paint
120-Second Reading
- Lead (Pb): non-detect
- Cadmium (Cd): 22 +/- 4 ppm
- Chromium (Cr)*: 13,900 +/- 400 ppm
- Iron (Fe): 202 +/- 60 ppm
- Copper (Cu): 3,468 +/- 81 ppm
- Zinc (Zn): 5,509 +/- 98 ppm
- Zirconium (Zr): 856 +/- 17 ppm
- Niobium (Nb): 388 +/- 13 ppm
- Indium (In): 25 +/- 5 ppm
- Tin (Sn): 15 +/- 6 ppm
- Antimony (Sb): 28 +/- 8 ppm
- Platinum (Pt): 335 +/- 50 ppm
- No other metals were detected in consumer goods mode.
*Chromium, Zinc, and Copper are likely primary ingredients in the paint (since Chromium and Zinc were not found in testing the unpainted glass, and Copper was found at a much lower level). Chromium is often a colorant for darker colors (like blacks and browns). The Antimony and Cadmium detected in this reading are likely in the glass (as noted above) as the paint was tested “in situ” on the glass background of the bottle — and the levels found are similar to reading #1 above.
Reading #3) Clear Plastic top cap
60-Second Reading
- Lead (Pb): non-detect
- Cadmium (Cd): non-detect
- Barium (Ba): 250 +/ 104 ppm
- No other metals were detected in consumer goods mode.
Reading #4) Peach Plastic Nipple Collar
60-Second Reading
- Lead (Pb): non-detect
- Cadmium (Cd): non-detect
- Titanium (Ti): 2,859 +/- 237 ppm
- No other metals were detected in consumer goods mode.
Reading #5) Clear Silicone Nipple
180-Second (Three Minute) Reading
- Lead (Pb): non-detect
- Cadmium (Cd): 14 +/- 2 ppm*
- Niobium (Nb): 340 +/- 9 ppm
- Indium (In): 17 +/- 3 ppm
- Tin (Sn): 6 +/- 4 ppm
- Antimony (Sb): 15 +/- 5 ppm
- Platinum (Pt): 21 +/- 12 ppm
- No other metals were detected in consumer goods mode.
*As noted above, these levels are considered “safe by all standards.” However, we still recommend using rubber nipples whenever possible given the prevalence of trace contaminants found in even “medical-grade” (or “food-grade”) silicone products — when testing using XRF technology.
