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 ). Since , 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). Tamara’s work was featured in Consumer Reports Magazine in February of (March print edition).

Answer: When I first got my hands on an XRF instrument and started testing things for Lead, one of the very first things I tested was my favorite set of Chantal mugs. I had a whole set of these mugs in different colors and I had purchased them to go with my favorite Chantal tea kettle. I was really surprised (and upset) that these mugs that I had purchased new at a reputable store in (made by what I assumed was a “reputable company,” no less) tested positive for Lead!
Those “favorite mugs” (pictured above) tested positive at 679 parts per million (ppm) Lead. Read more about XRF testing here!
Total Lead content in the glaze or coating of modern mugs (as detectable with an XRF) is not regulated. As long as mugs are not leaching Lead at the time of manufacture (when they are brand-new), they are considered to be safe to use — even if the Lead content of the glaze is very high. However, for context, the amount of Lead considered unsafe (and illegal) in the paint, glaze, or coating of a newly-manufactured item manufactured and sold as “intended for use by children” is 90 ppm or higher. The good news is that, since children’s items are regulated for total Lead content (as of ), newly purchased children’s mugs legally must have coatings below 90 ppm Lead, and my findings have confirmed that manufacturers are generally complying with this law — although I recommend sticking with children’s items manufactured in or later, as it took a while for the companies and their supply chains to get up to speed in their compliance with the new regulations.
Since testing those first mugs, I have probably tested more than 1,000 mugs (they are one of the most popular things that people ask me to test and people often have collections of 20 or more mugs in their homes). Nearly all of the mugs I have tested have had at least some amount of Lead — some at ridiculously high levels (in the tens of thousands of parts per million!) added to many of the pattern transfers, or used as an ingredient to brightly-colored glazes that help stabilize the color (as I understand it), but it is not necessary for this purpose — as some companies have demonstrated — it is quite feasible to make mugs that are completely Lead-free.

Years ago I learned of a case of an elderly Seattle couple who were both sick — with an illness that their doctor was having difficulty diagnosing. After some investigation, it turned out that this couple was Lead-poisoned — from drinking their coffee from the same Leaded mugs each morning as part of their breakfast routine! Please check out the articles linked below for more information on that as well.
Coffee is very acidic (as are many teas, juices, and some other beverages) and will leach Lead from mugs over time (especially from mugs with high Lead content, and are heavily used daily). This is even the case for mugs that ostensibly passed leach-testing at the time of manufacture.
If you have coffee every morning like I do, it is a simple investment in your health to make sure you have a Lead-free mug.

Other than possible free consumer goods XRF testing, which may or may not be available in your area, there is not a reliable, cost-effective consumer method for testing mugs for Lead and other toxic heavy metals. The most reliable “old-school” method for determining actual Lead content (as opposed to merely determining whether any is leaching at the time of manufacture) involves sending the mug to a lab for “digestive testing” — which is a method that traditionally necessitates complete destruction of the item that is tested — to determine the Lead content. That test generally costs in the $70 to $300 range per item, depending on the scope of the test (and also, unlike XRF-testing, can only determine the aggregate Lead content without a precise breakdown of the levels present in the surface glaze or coating vs. the levels in the base material/substrate)! Considering the inconvenience and expense of the existing testing options, it is much more cost-effective to limit your selection to known Lead-free options when choosing a mug!
#SaferChoice: Given the still-widespread use of Leaded glazes (and Lead-contaminated base clays) in ceramic mugs today, unless you have access to high-precision XRF consumer goods testing for testing every potential mug choice, it’s easiest/safest to just stick with clear glass mugs (so long as you make sure to avoid Leaded crystal)!

The mugs listed below are mugs that are the same as (or similar to) the Lead-free (or Lead-safe) ones I have personally tested and some of the mugs we use every day in our home.
I recommend most new items from Ikea (although avoid the bright colored ceramic mugs and other mugs with decorative elements, as Ikea mugs have recently been testing positive for Lead again in some of these brightly-colored ceramic glazes!) and pretty much any clear glass mugs (except Leaded crystal). Most vintage clear glass mugs are either Lead-safe or Lead-free, too (again, make sure you look out for and avoid Leaded crystal, though)!
I used to recommend mugs purchased at Starbucks because I had a streak there where every Starbucks mug I had tested was either Lead-free or below 90 ppm Lead. However, that streak ran out (I think with the expansion of their mug selection – and likely the consequent expansion of the number of manufacturers they are using). So I no longer recommend them for Lead-free mugs (in fact most of the new Starbucks mugs test positive for high levels Lead, Cadmium and / or Cobalt.)
Another great option for Lead-free mugs is something from a local potter who sources and mixes their own glazes. Potters will usually mark their wares “Lead-free” these days (if they are Lead-free) because that is a good selling point! If the mugs are not marked, ask the potter if they know if they use Lead-free glazes or not. Typically with these items there will be traces of Lead in the ceramic substrate (usually about 20 to 40 ppm) and the glazes will be Lead free (protecting the user from any potential exposure to lead in the ceramic substrate.) I do recommend avoiding handmade mugs with red or orange or yellow glazes – as those will often test positive for high levels of Cadmium (which is a known carcinogen.)
My favorite potter on the planet (who also does use Lead-free glazes) is Greg Williams/Ceramic Generations, of San Anselmo, California. I have known him since , and his pottery is so beautiful — each piece is a true work of art. He is an old-world artisan who still does business exclusively out of his shop and at craft shows, and does not have a website (but if you Google him you can quickly find his contact information)!
