Enamel

I would like to introduce one of the most basic tools for making enamel. It is a "melt can" made of clay, hand-made, and dried for 7 months at a temperature of 30 degrees Celsius. Once it is ready, it is slowly heated in a kiln, then maintained at a high temperature of 1400 degrees Celsius (2552 degrees Fahrenheit) and fired continuously for 8 days. The raw material needs to be heated in this "melt can" until it becomes a colorless transparent liquid like crystal. At this time, various metal oxides can be added to produce a variety of different colors: copper variable green and sapphire green, cobalt can be blue, magnesium is brown, platinum is grayed, mixed copper oxide, cobalt and Magnesium can be black, while boron stannate turns white. An average of 14 hours of firing in the kiln is required before it melts. Afterwards, the “melt” can be removed with a ladle, placed on a cast iron table (for transparent glaze), or thrown into a cast iron mold (for opaque glaze) for cooling.

After cooling, you can get a piece of hard material like glass, you need to crush it and grind it into a powder. Under normal circumstances, craftsmen are purchasing glaze powder of different colors. Of course, you can also buy glaze pieces, even crystal glazes that are the size of bath salts. However, the above various forms of glaze, their purity, can be applied to the dial, still far from.
