The sink fixtures are made of ceramic covered with enamel.

Vitreous porcelain is an enamel coating applied to ceramics, primarily porcelain, after firing, although the name can also refer to the finished piece as a whole. The coating makes porcelain harder, denser, and shinier, and it’s a common choice for things like toilets and sinks. Some artists also prefer it to “normal” pottery, and it has had a number of functions in ancient civilizations as well.

How is done

Most toilets that look like they are made of porcelain are actually made of vitreous porcelain.

The word “vitreous” means “glass-like” and that’s exactly what enamel does for ordinary ceramics: it makes them look shiny and reflective, while also maintaining and, in most cases, actually strengthening their durability. The enamel itself is usually made from composite minerals and powdered glass. It is usually sold as a powder that craftsmen and manufacturers must melt, in a kiln or specialized kiln, before using.

Vitreous porcelain has an enamel coating applied to porcelain and is commonly used in toilet bowls and sinks.

Once the glaze has reached its melting point, it can be painted, or “glazed”, onto the surface of the ceramic piece. Most of the time, the part being painted must be finished some other way, making this one of the last steps. The enamel should usually be left to dry for a while, then the piece refired to seal the coating. After that point, the item itself can usually be described as “porcelain”.

Main differences from other ceramics

Many people believe that porcelain is its own category of ceramic products, but this is usually not the case. With the exception of top enamel, these types of items, whether sinks, tubs, or other fixtures, are the same as unglazed, at least in terms of material composition. Most manufacturers start with ordinary porcelain products, which they later vitreous. The outer surfaces look different, but the underlying products tend to be identical.

Enamel gives the glass pieces a distinct shine and shine. However, it tends to crack more easily and is more prone to chipping when stressed. In most cases, it’s about the same price as regular porcelain, but a lot of it depends on the market and the precise application.

common uses

One of the biggest advantages of vitreous enamel is its ability to resist spills and stains. Porcelain is generally very tough, but it is densely porous, which means it sometimes absorbs other fluids, particularly when wet and exposed for long periods. Adding an enamel finish often makes it much easier for people to clean up stains, and this makes it very popular for sanitary ware. It also tends to be better at resisting germs and maintaining a hygienic surface.

Many bathrooms, sinks, and vanities that appear to be porcelain are actually glassy. Modern manufacturers use enamel regularly and often by default because of its advantages in the damp bathroom environment. It can also be used in large freestanding bathtubs and kitchen appliances, although kitchen uses tend to be less common because gloss often makes the material a little more brittle in situations where force can be applied, either through rigorous use of counters, cutting or storing heavy pots and pans.

artistic applications

Enamel has also been very popular in the arts for centuries. People have coated objects with enamel since ancient Egypt, and the application of powdered molten glass to metal objects was also a common practice in many cultures.

Historically, creating glass powder was possible by crushing glass or mixing colorless glass with metal oxide. Several designs were hand-painted onto the cooled glass. After painting, all items had to be baked inside a large wood-fired oven that was capable of heating to very high temperatures. Perhaps the best-known enamel object in history is the Fabergé egg.

During the 1800s, Peter Carl Faberge, a Russian jeweler, was commissioned by the Tsar to create an Easter egg for the Tsar’s wife. He created an egg made of metal, coated with enamel and encrusted with precious jewels. From that day forward, Fabergé eggs were the height of sophistication and some people still collect them today. During the Art Nouveau period, coating objects with glaze in the style of vitreous porcelain became immensely popular. The material itself is chemically resistant, durable, smooth, shiny and nearly impossible to burn – one of the reasons so many antique enamel items remain intact today.

cleaning tips

Experts usually recommend cleaning enameled products with soap and water after each use. Although it is generally moisture resistant, keeping it dry whenever possible is also advisable in most cases. Abrasive scrubs and tough sponges should usually be avoided since these can scratch or dull the surface. Artistic pieces should be regularly dusted and polished with a dry cloth to keep them shiny.
