Get PriceAluminum, allcopper, or glass cookware will not work unless they have a layer on the bottom with magnetic properties. Many manufacturers have started adding a magnetic layer to the bottom of these pans, but older, nonmagnetic pans simply will not work. Aluminum and copper require much higher frequencies to generate the heat needed to cook food.
Get PriceGalena. Galena is capable of taking an equally heavy toll on workers and amateur researchers who are exposed to it. Contact with specimens may lead to lead dust exposure, while workers in mines face a high risk of poisoning from contact with the mineral and the deadly dusts released through production.
