They look and feel like stainless steel, however they appear to have some kind of coating. The surface of my skewers looks slightly more dull and grey than my stainless steel cookware.
Furthermore, I observed a dark grey residue coming off my skewers under the following circumstances:
- Straight out of the box if I rub my fingers across the surface.
- After putting them through the dishwasher if I rub my fingers across the surface.
- After dishwasher if I rub a white tissue across the surface.
I noticed that there is also a Prop 65 warning listed in the Webstaurant link above, which states:
WARNING: This product can expose you to chemicals including lead, which are known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information, go to www.p65warnings.ca.gov.
Is it likely that my skewers are indeed coated in something, and if so, what is this coating and why is it possible to contain lead?
