In daily life, the toilet is indispensable, but how many people know how it was born? Today I will tell you how it was born.
Everyone knows that the Toilet Suite is ceramic, but its previous life is clay. The prepared expression is called clay is shaped and burned.
Let's break down its production process:
First, choose raw materials
Second, making mud
Grind with clay, ore, etc., and mix it with a large machine to make a slurry through a certain ratio.
Third. For glaze production, small factories can purchase raw glazes made by others. Each glaze produced has a unique formula, and the color of the ceramic produced is the same. The glaze purchased and sold in a small factory must be different from the glaze produced in a large factory. High-imitated products will have different colors.
Fourth, high-pressure grouting, one-time molding
Fifth, blank inspection before glazing
Sixth, glazing
