Can the uneven glass be polished?

glass polishing refers to removing the lines, scratches and other defects on the glass surface by chemical or physical methods, improving the transparency and refractive index of the glass and making the glass more vitrified.

Method 1: fire polishing

Softening the glass surface by flame and the impact of fire on the glass can solve some material lines on the surface of the glass product

but the smoothness of the treated glass surface will be reduced. Generally, the mouth of the hollow vessel glass is rough after cutting

.

Suitable materials for glass: soda-lime glass and high-jump silica glass

Negative effects: ! ! Before polishing, the polished part should be sanded, and the pure plane

should be polished by emery disc with a mesh of more than 4. There are many tools and materials used in this polishing method, but the best effect

is wool wheel+cerium oxide (common name: rare earth polishing powder), so the manufacture and use of machinery are not detailed here.

Suitable material glass: most glass products

Negative effects: relatively slow

Method 3: Acid polishing

The surface of glass is treated by the corrosive action of acid on glass, and the

surface of glass also needs to be sanded before polishing, because acid polishing can reduce the thickness of glass a lot, but it may not be able to completely remove the glass lines. It

Non-professionals and companies with complete equipment do not recommend personal experiments.

Suitable material glass: any glass (but the effect after polishing is determined by the glass material itself)

Negative effects: the smoothness is not well controlled, and the water chestnut of glass products is damaged to some extent.
