anyone else worried about cadnium in vintage le creuset?
Just wondering... In love with le creuset and bought a lot of the flame color on ebay, only to read that there is cadnium in the exterior glazes on the older ( orange, red and yellow) stuff. I know it is only on the exterior but does heating it cause any health threat. I'd love more information.
I am sure it is very bad for you. If you send the piece to me I will make sure that it is properly disposed of.
Cadmium Sulfide and Cadmium Selenide were common pigments to produce yellow and red respeciively and likely combined to produce orange. Cadmium is highly toxic and a carcinogen. This is the chemistry part and fact. The unknown part is just how likely is it that you will get cadmium or cadmium fumes from your le creuset? The pigment is contained in a ceramic glaze, so I would think it to be unlikely, but that is not my area of expertiese. Although I doubt you could use a cadmium pigment today, most of the concern is with handeling the raw materials, not the finished product. It's not like you are going to take a surface grinder to your le creuset, and set the cadmium free. I seriously doubt you will get it hot enough to release vapor, that would take 765°C, about three to four times what your oven can do.
Personally, I'd be a lot more concerned about the concentrations of cadmium in the air and water from coal-fired power plants. Lead, mercury, and arsenic too.
