Production process of glass jars

The glass jar production process mainly includes, raw material preprocessing. Crush bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.), dry wet raw materials, and remove iron from iron-containing raw materials to ensure glass quality. Batch preparation and melting. The glass batch material is heated in a pool kiln or pool furnace at a high temperature of 1550~1600 degrees to form a uniform, bubble-free liquid glass that meets the molding requirements. Put the liquid glass into the mold to make glass products of the required shape, such as flat plates, various utensils, etc. for heat treatment. Through annealing, quenching and other processes, eliminate or generate stress, phase separation or crystallization inside the glass, and change the structural state of the glass.
