Material: crystal glass
Process: manual blowing
Size: 12*7*6.5cm
Color: transparent, black
The crystal glass material is elegantly placed, and the texture is transparent and crystal clear. The mouth of the cup is round and natural, and the hand-blown vertical grain texture is more textured. The bottom of the cup is stable, not easy to topple, and placed steadily. Two-color design, simple design, delicate touch.
Glassware production process:
①Pre-processing of raw materials. Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry the wet raw materials, and remove iron from the iron-containing raw materials to ensure the quality of the glass.
② Preparation of batch materials.
③Melting. The glass batch material is heated at high temperature (1550~1600 degrees) in a pool furnace or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.
④Forming. Put the liquid glass into the mold to make glass products of the required shape, such as flat plates and various utensils.
⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of the glass is eliminated or generated, and the structural state of the glass is changed.
