Why is a lead frying-pan sleeve bad idea?

Lead is a toxic metal that can cause serious health problems, including brain damage, learning disabilities, and kidney failure. It is especially harmful to children and developing fetuses.

Because lead is a soft metal, it can easily leach into food when it is used in cookware. This is especially true when the cookware is heated, as this can cause the lead to vaporize and contaminate the food.

For these reasons, it is never a good idea to use lead cookware, including lead frying-pan sleeves. If you are concerned about the safety of your cookware, you can have it tested for lead by a qualified professional.
