Jewellery made using enamel techniques is not common, mainly because the craftsmanship involved in making such jewellery is extremely tedious, and the value is not as immediately discernible as that of gemstone-inlaid pieces. Therefore, they are not common in ordinary jewellery markets.
So now, besides high-end jewellery, this technique is rarely used in various types of jewellery. After all, for those in the jewellery industry, the primary purpose of making jewellery is to make money, so naturally, they have to satisfy the needs of their customers.
The enamelling process involves multiple firings, as each time the glaze is applied and fired, it contracts, and then more glaze needs to be added and fired again.
This feature allows for further artistic creation, such as adding different additives and using different temperatures during the two firings, resulting in more complex and diverse colors.
