Processing of glassware

Overview of glassware processing
Glassware refers to natural or synthetic glass as the main raw material, through a series of processing technology made into a variety of shapes and uses of utensils. These appliances are widely used in home life, decorative arts and industrial fields.

Classification of glassware
According to the different use and production process, glassware can be divided into many types, such as wine glasses, vases, cups, plates and ornaments.

History and development of glassware processing
Glassware processing has a long history, dating back to the Mesopotamian civilization of 3000 BC. With the passage of time, glassware processing technology has continued to develop, and gradually formed a variety of different production techniques and styles. Modern glassware processing technology has been widely used in a variety of new technologies and materials, such as modern machinery manufacturing technology and new glass materials, making the quality and variety of glassware more diverse.

Glassware processing process
Raw material preprocessing
The massive raw materials (such as quartz sand, soda ash, limestone, feldspar, etc.) are crushed, the wet raw materials are dried, and the iron-containing raw materials are treated with iron removal to ensure the quality of the glass.

Compound preparation
Mix the raw materials according to the formula ratio to ensure an even distribution of raw materials 2.

Fused glass
The compound is heated at high temperature in the pool kiln or pool furnace to form a liquid glass that is uniform and free of bubbles and meets the molding requirements 2.

molding
The liquid glass is put into the mold to make the glass products of the required shape, such as plates, various utensils, etc. Forming methods include manual blowing and mechanical blowing 2.

Hand blowing
Hand-held blowpipe picks material from the crucible or the pool kiln at the feeding port, and blows it into the shape of an instrument in the iron or wood mold. This method is suitable for making smooth round products or using color fusible particles to stick on the milky turbidite, and the natural melting flow of various colors can be blown into natural tableware 3.

Mechanical forming
After receiving the material, the blowing machine automatically closes the iron mold and blows it into the shape of a vessel. This method has higher efficiency and better quality than simply blowing with a blowing machine.

Heat treatment
By annealing, quenching and other processes, eliminate or generate stress in the glass, phase separation or crystallization, and change the structural state of the glass.

Surface treatment
The surface of the glassware is polished, frosted, etc., to improve its beauty and performance.

Latest technology and innovation
Recently, Anhui Fengyang County Qianli Glass Products Co., Ltd. has obtained a patent entitled "an energy-saving glassware softening molding equipment and processing technology", which marks an important step in the glassware processing industry in technological innovation 4.

Application field
Glassware is widely used in home life, such as tableware, wine utensils, vases and so on. In the field of decorative arts, glassware has become a highlight of indoor and outdoor decoration with its unique color and luster. In the industrial field, glassware also has a wide range of applications, such as chemical laboratory equipment, lighting equipment, medical equipment, etc.

Through the above detailed process flow and technological innovation, it can be seen that glassware processing is not only an ancient art, but also a constantly developing science.
