Question from YH
After reading Dr. Marcela’s article on stainless steel found on your website, I think it is time for me to buy Vision cookware. I read that to produce stained glass, lead is used. Will lead leak into food prepared in stained glass cookware (Corning Vision)?
Is it practical to buy glass pans? I read that food would stick and that glass cookware is one of the stickiest (food also stick on stainless steel; cast-iron is very non-stick). Also, I am afraid that it might shatter. I think having water in pots is safer than stir-frying in glass pans (which may be dry). I am still afraid that glass cookware may break and shatter any time. Thanks

First of all, colored glass doesn’t contain lead. See Q&A: Colored Glass and click on the “Colored Glass Chemistry” link to see what is used to make different colors of glass.
Lead is used in the solder that holds the glass together to make colored glass windows. But it is not in the glass itself.
I myself have used Corning Visions cookware for over twenty years without a mishap, though others have reported otherwise (see Q&A: can visions cookware and pyrex shatter while cooking?). I do not stirfry in it, but use pots for things like warming soup, boiling eggs, etc.
