(1) Pre-processing of raw materials:
Massive raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed to dry wet raw materials. Iron-containing raw materials are removed to ensure glass quality.
(2) Preparation of batch
(3) Melting:
Glass batch is heated at high temperature (1550-1600 degrees) in a tank kiln or furnace to form uniform, non-bubbly liquid glass that meets the forming requirements.
(4) Forming:
Put liquid glass into the mould to make glass products of desired shape, such as flat plates, various utensils, etc.
(5) Heat treatment:
By annealing and quenching, the stress, phase separation or crystallization in the glass can be eliminated or produced, and the structural state of the glass can be changed.
