Enamel - Burning


The burning temperatures and times can vary because of steel thickness, different parts and frits but the average is about 825 – 850°C at 5 -10 min.
During the burning process there is a chemical reaction between the adherence oxides (cobalt oxide, nickel oxide) and the steel which leads to an adhesive layer and an inseparable compound. As there are no adherence oxides in a white porcelain enamel the steel has to be nickel coated before directly enameling white. The nickel layer is the adhesive layer between the steel and the white enamel.
