What is the pressed glass technique?

Patterned glass technique is a process of making flat glass by rolling. The specific process is to use a roller with patterns to press patterns on one or both sides of the glass before the glass hardens, so as to make embossed glass with a specific pattern. The following is a detailed introduction:
1.Manufacturing process
Single roller method: inject glass liquid into the rolling forming table, the table or the pressing roller is engraved with patterns, and the glass liquid is rolled with the pressing roller, and finally the embossed glass is placed in the kiln for forming.
Double roller method: divided into semi-continuous rolling and continuous rolling, cold water is injected into the glass liquid, rolled with the pressing roller, and pushed into the kiln. The upper roller is used for polishing, and the lower roller surface is engraved with patterns, which can make single-sided embossed glass.
2.Product features
Transparent but not transparent: the uneven pattern on the surface causes the light to diffuse, and the blurred image of the other side can be seen from one side, providing privacy protection.
Decorative: It has various beautiful patterns, such as rain flowers, cloth patterns, gold threads, etc., and has a good artistic decorative effect.
Higher strength: Compared with ordinary flat glass, it has greater strength and can be installed in a large area in a variety of functional spaces.
3.Application areas
Architectural field: Used for doors and windows, indoor partitions, bathrooms, etc., which not only separates space, but also ensures lighting and privacy.
Home decoration: Make screens, partitions, furniture, etc. to add beauty and artistic atmosphere.
Automotive industry: Used for headlight lampshades to soften the light and expand the irradiation range, improving the performance of headlights.
Solar energy field: Ultra-white embossed glass is used in solar photovoltaic and photothermal conversion systems to improve the photoelectric conversion rate.
4.There are obvious differences between embossed glass and ordinary glass in terms of manufacturing process, appearance, optical properties, strength and application scenarios:
5.Manufacturing process
Embossed glass: It is made by calendering method, and the pattern is pressed out with a roller with patterns before the glass hardens.
Ordinary glass: Usually transparent flat glass without special pattern treatment.
Appearance
Embossed glass: There are various patterns on the surface, such as rain flowers, squares, rainbows, etc., which have a three-dimensional sense and decorativeness.
Ordinary glass: The surface is flat and smooth, usually without patterns, and has high transparency.
Optical properties
Embossed glass: It is light-transmitting but not transparent. When light passes through, it diffuses, blurs the vision and protects privacy.
Ordinary glass: It is light-transmitting and transparent, and the vision is clear and unobstructed.
Strength
Embossed glass: It is stronger than ordinary glass and can be installed in a large area in a variety of functional spaces.
Ordinary glass: It has relatively low strength and is fragile.
    In summary, embossed glass technology gives glass the characteristics of beauty, practicality and diversity through a unique manufacturing process, and is widely used in architecture, home, automobile and solar energy.
