【Manual】
The thing used for manual tracing of gold is very simple. It is to place the glass tea set to be decorated on the turntable, using different shapes and sizes of paintbrushes, brushes, and containers with golden water; when drawing the gold edge of the tea set, the worker fixes the paintbrush and the brush at a certain position. Rotate the turntable again to draw gold edges and other patterns on the mouth of the cylindrical tea set and other parts;
【mechanical】
The principle of the mechanical gold-tracing process is similar to that of manual gold-tracing, except that the tea set, brush, and brush are fixed on a machine. The movement of the mechanical tray drives the rotation and revolution of the glass tea set and the gold-tracing device. Synchronous action of timing positioning completes the gold-tracing. , The advantage of mechanical gold tracing compared with manual gold tracing is high work efficiency;
【drying】
After the gold pattern is dried, it needs to be roasted to decompose the organic compounds and form a smooth and shiny thin layer on the glass surface after reduction; the roasting temperature is very important and needs to be determined according to the softening temperature of the glass tea set and the formula of gold water. Generally, the baking temperature of high-lead glass is about 480℃, soda-lime glass is about 560℃, and borosilicate glass is about 650℃;
