These are my favorite mugs – the mugs my family uses every day in our home. I like them so much that I even bought a set for my son to get his kitchen away at college started!

Is this test result enough to conclude that any batch of Cosy mug from Duralex will be lead and cadmium free as well?
Judging by the article title, I’d say that’s a given.
Are these safe levels for barium and titanium? I can’t seem to find the answer to that any where. My husband just had a heavy metal test and barium was one of the things that came back high.
Tamara, You wrote that the Duralex mug contains:
” Barium (Ba): 2,183 +/- 766 ppm
Titanium (Ti): 115. +/- 59 ppm … ”
What are the acceptable levels of Barium and Titanium?
Do these leach into a hot beverage?
Barium and Titanium are common to find in glassware and I don’t have a concern in this application. There are no applicable regulatory limits that I am aware of.

I have read in reviews on Amazon that tempered glass can explode. One report of Duralex exploding in a cabinet. Also Libbey and Ankor Hocking do not label them as microwave safe. There are reports of them exploding in the microwave. Is this a concern with tempered glass?
Do you put these mugs in the microwave?

I read with glass you have to worry about aluminum. Maybe that’s why my heavy metal test came back with high aluminum. I don’t use deodorant and I don’t use aluminum foil and I eat organic so I was stumped. I do cook with those Pyrex glass pans. Just wondering why aluminum wasn’t tested with these. Thank you for doing the other task though. This might be the best thing we can get our hands on. I just learned about lead in the dishes and now I know why my lead was high. Good grief. Thank you for the work you do.

Also wondering about the pictures on Amazon of glass dishes that explode (in microwave, in cabinet, on table). It makes me hesitant to buy these. What is your opinion?
Do these mugs test for any amount of aluminum?
