What is porcelain enamel?

Porcelain enamel is effectively inorganic glass – an anti-corrosioncoating of metal parts based on silicon. During melting, thanks to the adhesive force, porcelain enamel adheres to the surface of metal and creates an integrated coating. The adhesion properties are achieved and expressed only upon reaching the melting temperature of approximately 840°C.

How is porcelain enamelling done?

Porcelain enamelling in general is done by painting, soaking or spraying. The selection of the technology depends on the foundation material and the resulting effect desired. Smaltovňa, s.r.o., uses spraying technology, during which the porcelain enamel is sprayed in a consistent form using pneumatic equipment on a specially modified foundation sheet metal KO-SMALT.

Why is porcelain enamel used?

Porcelain enamel extends the lifespan of metal. Thanks to porcelain enamel a metal object becomes practically rust-resistant, so long as the porcelain enamel layer is not mechanically damaged. We can colour metals with porcelain enamel and the colour remains forever the same. With porcelain enamel a product also acquires high-level aesthetic properties; the surface is shiny and easily cleaned – much like glass. With its similarity to glass, porcelain enamel requires careful handling – it is fragile and sensitive to collision.


Various types of enamel depositing exist for the base material,and they are combined according to the type of resulting effect we want to achieve. Porcelain enamel can be laid on by painting, soaking or spraying. Smaltovňa, s.r.o., uses spraying technology, in which enamel is sprayed in a consistent form by pneumatic equipment on a sheet-metal base. A specially modified sheet metal, KO – SMALT, is used as the base metal.

Porcelain enamel:

Porcelain enamel is inorganic glass, an anti-corrosive coating for metal itemsbased on silicon. Upon melting,porcelain enamel has adhesive properties, which occur only after reaching a temperature of about 840 °C. With the help of adhesive force enamel sticks to a surface, thus creating an integrated coating, which in the end result creates the effect necessary for theaims of the company.

Properties of porcelain enamel products:

In terms of lifespan, after treatment of a metal surface with porcelain enamel, the metal becomes practically rust-proof, so long as the layer of enamel is not mechanically damaged. Porcelain enamel is also characterized by the lifespan of its colouring, which does not weaken or fade. One of the other traits of porcelain enamel is its brittleness, which at the same time is also a disadvantage. Otherwise porcelain enamel has high-level aesthetic properties: it has a shiny surface andis easily washable, much like a surface of glass.
