XRF test results for the 2-cup clear glass measuring cup (by CuttleLab) pictured (purchased in 2022 off of Amazon.) Affiliate link: https://amzn.to/3NuXq0B
My husband LOVES this measuring cup [he has been using it for measuring out the just-boiled water for my morning coffee]! He says he loves that it has permanent markings that are molded into the glass [rather than the usual painted markings other brands use — paints which consistently test positive for unsafe levels of either Lead or Cadmium, painted markings can tend to wear off over time!]. He also thinks it’s really great that it has a cute little citrus juicer to go on top of it — AND that the juicer actually works (so many glass citrus juicers are not quite sharp enough to be useful!)
Several of you have asked if the measurement markings are “true”…we have found them quite serviceable, but I will double-check with a little experiment in the next day or two and get back to you on how exact they are. In the meantime, we are very happy with this purchase for our home! If you want a more exact measurement or generally prefer stainless, here’s a link to my favorite stainless measuring cups.

So excited for this!! Just ordered! Have you used boiling water in yours yet?
Yes Janell! My husband uses boiling water in it every day! He purchased it specifically to use to measure the boiling water for coffee (he’s trying to get super scientific about making the perfect cup of coffee for me every morning!) 🙂
Thank you! I have been looking for BOTH items for a LONG time. I really appreciate your help and I used you link. I have been concerned about the measuring cup I use after seeing one of your posts.
Very excited about this!! I’ve been looking for a juicer for awhile now! Thank you!
Yeah, my main concern is accuracy. I have a couple batter bowls from a couple brands, in both 4 cup and 8 cup sizes, but the raised glass markings just are not reliably accurate for anything other than approximation.
Bay Mom says
Any concern for the barium and chromium… aren’t those toxic as well?
Sue Peters says
Would love to know this as well.
Great find…thank you!
Thanks! Excited to order this but disappointed it isn’t microwave safe. Still looking for glass alternative to my Pyrex measuring cup to go in the microwave. Thank you for all your hard work!
PLEASE continue the search for an item that meets these specifications and is microwavable. While I try to limit the use of the microwave, others in my family do not, so we still have the toxic Pyrex measuring cup, which I would just love to toss out….but I just can’t find an alternative. I have the 8 ounce tri pour Anchor Hocking (not microwavable), a 2 cup glass measure that is not microwavable, a 4 cup batter bowl, and an 8 cup batter bowl. I simply cannot find a non-toxic glass measuring cup that is microwavable in the 2 cup or even 1 cup size; I have been searching literally for years… There would be a huge demand for some firm willing to make these!
Agree 100%. I use to heat up water in the microwave for coffee, tea, oatmeal, jello – should I not be doing that? Why would it not be microwaveable yet hold up in d/w & pour boiling water into. Sorry newbie, just learning basics. Thank you Tamara for your research, time, persistence, commitment & education to something that we all need to know & should be adequately gov’t regulated but yet again another area that is not. Thank goodness for momma warriors like you
We use ours in the microwave all the time!

Hi thanks for all the work you do. I had the same question that bay mom had about the barium and chromium since this measuring cup has high of these metals and I did note that some other items you have listed as lead and cadmium free have also had high levels of either chromium or barium.
Thank you so much for sharing! I just realized my juice is crystal and not glass. So I’m switching ASAP.
The Cuttle Lab measuring cups have been out of stock for a while now. Also, the product info says they are not microwaveable.
What else do you recommend?
on my http://www.ShopLeadSafeMama.com site there are a few other linked options on the measuring cups page. Target also has a Target-branded glass option that is Lead-free.
