vitreous enamel has a long history dating back to the early civilization stage of man. from the  craftwork of ancient time,  glass  paste was  applied  to  the metalwork.

enamel  coating  was  one of  the oldest decorating technologies. many civilized nations in ancient times gradually learned to use enamel to add gloss and color to ornaments thus making them more beautiful. the technology of enamel was developed then.

even now, enamel is still the  only  way to protect metal with complicated non-organic coating material. it has the same quality, components, and characteristics as glass. that is, innocuity, easy to clean, rust-resistant, abrasion-resistant and heat-resistant. there are also a large number of colors available that will remain unchanged with its shine and brightness. with these characteristics, enamelware has become very popular in household, architecture and industrial application.

in fact, there is a big difference between ancient and modern enamel. in ancient times, enamel was coated on durable noble metal, only for decoration. today, enamel is widely used on ferrous metal (not noble and oxidative metal, such as steel, cast iron and aluminum) for protection. therefore, the cost islower and can be used for mass production for consumer products, from casseroles to tabletops, from ovens in the kitchen to bath tubs in the washroom, from road signboards to building deck board etc. enamel products are becoming more and more popular.
