Porcelain Knobs
Posted in Garden Antiques on 03/26/2008 09:39 pm by adminWhat are the knobs and tubes used in knob and tube wiring made of, on a chemical level?
I know that they made of porcelain, but I don't know what porcelain is made of... It might depend on the brand, but I am looking for what is most generally used. (This is for a project for my ceramics engineering class.)
These are most likely made from an electrical grade porcelain, like steatite. Steatite is a Magnesium - Alumina - Silicate.
