Glass Teapot China

One of the most common molding methods in the manufacture of glassware can be divided into manual blowing and machine blowing. Manual blowing is commonly known as "blowing a big bubble." In the 5th century, this technique was transmitted from Central Asia to China, which stimulated and drove the development of China's glass manufacturing process. Since then, China has used the blowing method to manufacture hollow glassware, namely glass tea pot. The method is to first draw the glass melt from one end of the copper or iron blowing cylinder, and then blow the gas at the other end of the blowing cylinder to form the desired shape of the molten metal, and finally cut it with scissors. During the blowing process, the technician's hand keeps rotating the blower, on the one hand to keep the glass melt from escaping, and on the other hand to use the viscous flow of the glass to shape the desired shape. In the meantime, coordination and cooperation must be achieved, and the product can be perfected, which is quite difficult. The size, thickness, shape, and the like of the glassware are controlled and controlled by the magnitude of the blow volume, the degree of urgency, and the rotational speed of the blower.

Mold blowing: Relative to moldless blowing, first use copper or iron to make a hollow model, then use the blower to draw the glass melt, and put it into the mold to blow until the melt completely fills the model inner wall. After cooling, the mold is ready. In this way, it is possible to manufacture a special shape such as a square or a polygonal shape, and a complex portion such as an ear, a mouth, or a foot required for the object. The mold blowing greatly enriches the shape and artistry of the utensils.
