1. Preparation of raw materials:
The first step in making coloured glaze is to prepare suitable raw materials. Colored glass is mainly composed of quartz sand, alkaline substances and rare earth metals. These raw materials need to be carefully screened and mixed to ensure the quality and color of glass.
2. Melting:
Put the prepared raw materials into a special melting furnace for high-temperature melting. The temperature of the furnace is usually above 1200 degrees Celsius, so that the raw materials are completely melted and uniform glass liquid is formed.
3. Forming:
The molten glass will flow out through the small holes in the bottom of the furnace and fall into the prepared mold. The molds can be of various shapes and sizes, and different glazed products can be made as required. The glass liquid gradually cools and solidifies in the mold.
4. Cooling:
Molded glazed products need proper cooling. The speed and mode of cooling have an important influence on the quality and appearance of glass. Generally speaking, glass products will be cooled slowly in the natural environment, or controlled by special cooling equipment to ensure the stability and transparency of glass. 5. Grinding and polishing:
The cooled glazed product may have some rough surfaces or incomplete shapes. In order to improve its smoothness and aesthetics, it needs to be polished and polished. This step is usually carried out manually or mechanically, and tools such as grinding wheel, grinding plate or polishing agent are used to make the surface of glass products smooth and bright.
6. Carving and decoration:
In the process of making glass, you can also carve and decorate. Various patterns, patterns and characters can be carved on glazed products through carving tools, magnifying glasses and meticulous manual skills. In addition, it can also be decorated with pigments, metal wires, jewelry and other materials to increase the artistic sense and value of glass products.
7. Baking and curing:
Glazed products need to be baked and cured after making and decorating to enhance their stability and durability. The baking temperature and time will vary according to the composition and thickness of the glass. The baked glass products will be harder and more durable, and the wear resistance and oxidation resistance will also be improved.
