How do you get Vitreous Enamel?
We make Vitreous Enamel by smelting naturally occurring minerals, such as sand, feldspar, borax, soda ash, and sodium fluoride at temperatures between 1200 °C and 1350 °C until all of the raw materials have dissolved. Other metallic mineral may be added to give specific properties or colour.
Is Vitreous Enamel the same as porcelain enamel?
Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). Enamel can be used on metal, glass, ceramics, stone, or any material that will withstand the fusing temperature.

How did they make old porcelain signs?
THE ORIGINS OF PORCELAIN ENAMEL SIGNS During fabrication, a powdered glass composition (frit) is applied in layers to a metal base. The lettering is carefully stenciled on by hand. The sign is then fired in a kiln, which causes the glass and metal to bond. Porcelain enamel is more than a surface paint.
Is enameled cast iron better than cast iron?
