Like many of the ceramic arts, the very early history of applying glasses to metals is lost in antiquity. The knowledge of the discovery of glass is scarce, but it is thought to have been discovered in Persia many centuries before Christ. Of course, it is safe to say that glass covering metal was a late development. However, there is evidence that metal was covered with glass for artistic effect long before the time of Christ.

The actual art of enameling may have originated in western Asia. The earliest work was done in various colors, applied to gold and used for jewelry. As the art developed, the highest order of artists and craftsmen, which had the ability to apply the glass to gold and jewelry, finished many of the objects with religious nature. In the British Museum is an enameled Celtic shield found in the Thames. This piece is thought to be nearly 2,000 years old, and even after its'long subjection to brackish water, it is still beautiful. The technology of glass applying to small metal pieces was developed to its highest point about 1750 in Battersea.

Before the 18th century, almost all enameling were applied to gold, silver and copper. About that time. At about that time the enameling of ferrous metals began. Cast iron has reached quite a high level of development, The first attempt at enamel was made with this metal at that time. With the advent of Bessemer and the Siemens processes for steel making, rapid strides were made with that metal, and it was first successfully enameled in the nineteenth century. With the enameling of ferrous metals began, people began to make enamel products for practical purposes. Kitchen utensils were originally made of cast iron, but later, when steel was developed, it was found that these items could be made more cheaply by stamping with steel. At present, the steel hollow ware industry is huge. Since the beginning of the 20th century, the application of enamel to these two metals has developed rapidly and steadily. Enamel steel products are the most common kitchen utensils, signs, washing machines, bathtubs, refrigerator linings and stove parts. Cast-iron products are mainly bathtubs, sinks, heavy stoves, scales and other lesser-known items. Both industries are moving forward side by side, each with its own technology. One of the latest developments in the enamel steel plate industry is the application of enamel steel plates to the facade of homes and shops.

Glass-Fused-to-Steel for roofing and interior decoration have been manufactured for many years. The chief advantages of this material are its case of cleaning, long life and its ability to retain its color and finish. Late in the nineteenth century, a German American by the name of Casper Pfaudler, after observing that the employment of vacuum hastened the fermentation of beer, invented and patented a method of vacuum fermentation. At that time there was no suitable material from which large fermenting vessels could be made to maintain a dimin ished pressure. Many experiments were made with various existing materials, in cluding stone, terra cotta, cast iron and plate glass. A firm in Birmingham endeavored to line a rectangular tank with plate glass with the sides embedded in concrete and the top in lead, but when the vacuum was applied the vessel proved unsuccessful. Enamelled cast iron was also tried, but the experiments were unsuccessful because the enamel was of a higher melting-point than the cast iron. This experiment, of course, was made before cast iron enameling had reached its present high stage of development. This latter experiment led to a trial with enameled steel, which it might be said was the actual beginning of the Glass-Fused-to-Steel tank. At that time, Glass-Fused-to-Steel was not nearly as common as to-day, and no enamel had been applied to the heavy gauge material required for a beer fermentor working under vacuum. A great amount of experimental and developmental work was done before the process was finally brought to a com mercial stage.

Established in 1989, Center Enamel is the first enameled products manufacturer in China with the enameling technology to produce enameled cookware, enameled bathtubs and enamel glaze. And in 2008, we began to use the enameling technology to manufacture Glass-Fused-to-Steel tanks. We apply for more than 20 enameling patents in the past 30 years and become the first  Glass-Fused-to-Steel tanks manufacturer and supplier in China and the most experienced Glass-Fused-to-Steel tanks manufacturer in all of Asia. Until 2023, Center Enamel Glass-Fused-to-Steel tanks have been exported to more than 90 countries including USA, Australia, Canada, Malaysia, Indonesia, Russia, UAE, Panama, India and South Africa etc. The superior product quality and prompt service gain us worldwide recognition. Make your next tanks perfect, make it Center Enamel.
