Zománcport

Zománcport is a fine powder used in various industrial and artistic applications, primarily for coating metal surfaces. It is a type of glass that has been ground into a very fine particulate form. The composition of zománcport can vary significantly depending on its intended use, but it generally includes silica, fluxes (like sodium carbonate or borax), and metal oxides that act as colorants or opacifiers.

The manufacturing process typically involves melting the raw materials at high temperatures to form a molten glass. This molten glass is then rapidly cooled, often by quenching in water, to create a brittle frit. The frit is subsequently ground into a fine powder using specialized milling equipment. The particle size and distribution of the zománcport are crucial for achieving a smooth and uniform coating.

When applied to a metal object, zománcport is usually suspended in a liquid medium, such as water or an organic solvent, and then applied via methods like spraying, dipping, or electrostatic application. The coated object is then fired at high temperatures in a kiln. During firing, the zománcport particles melt and fuse together, forming a durable, glassy layer that adheres strongly to the metal substrate. This process, known as enameling or vitrifying, provides a hard, chemical-resistant, and often decorative finish. Zománcport is widely used in cookware, sanitary ware, appliances, jewelry, and decorative arts.
