Powder Enamel Firing Ovens
Glass Frit. Fused to Steel.
STRONG3000 Powder Enamel Firing Ovens fire the applied enamel powder (glass frit) at approximately 780–850°C to fuse it onto the steel surface. Enamel is a glass — never paint — and at this high temperature the molten glass chemically bonds to the metal. The ovens are engineered with refractory-grade construction and high-temperature durability.
The Temperature Where Glass Fuses to Steel.
Powder enamel firing is the process of melting glass frit powder applied to steel and fusing it to the metal at high temperature. For steel, the typical firing temperature is ~780–850°C, where the frit melts, spreads and — as it cools — forms a hard, glass-like enamel layer that is chemically and heat resistant. Enamel is a glass coating — never paint.
This temperature range demands a refractory brick or ceramic-fiber lining, high-temperature-rated structural elements and stable temperature control. Available with gas or electric heating, the ovens work in coordination with the STRONG3000 enamel application line.
