Production
Enamel – The unknown known
Although enamel does not occur in nature, it consists entirely of natural raw materials. The raw materials quartz, feldspar, soda, borax, aluminium oxide and other metal oxides are melted at high temperatures to produce enamel frits. They are the basic materials needed for enamelling.
The frits are ground with or without water using different colouring agents and other additives. All these processes are environmentally friendly. Organic substances and solvents are not required. This makes enamelled products easy to recycle.
Enamelling means: enamel slurry – an aqueous suspension -, or enamel powder are firmly bonded to the carrier material by firing in one or more layers.
Steel, cast iron, aluminium and stainless steel are suitable substrate materials.
Steel is the most important base material.
