Embossed glass is not entirely produced through etching processes. Embossed glass, also known as patterned glass or rolled glass, is primarily made using the rolling method rather than solely through etching. Below is a detailed explanation of the production process of embossed glass:
Rolling method
Embossed glass is processed using the rolling method. During the rolling process, molten glass is rapidly cooled and rolled through rollers with patterns or designs, creating various patterns and designs on the surface of the glass. This process can produce embossed glass with patterns on one or both sides. The specific methods for manufacturing embossed glass using the rolling method include:
Single roller method: The molten glass is poured onto a rolling forming table, which can be made of cast iron or cast steel. The table surface or rollers are engraved with patterns, and the rollers press against the surface of the molten glass, after which the embossed glass is sent to an annealing furnace. This method is currently used only in small quantities for the production of glass crafts.
Double roller method: The molten glass passes through a pair of water-cooled rollers, which pull it forward into the annealing furnace as they rotate. Generally, the lower roller has a concave-convex pattern, while the upper roller is a polishing roller, thus producing embossed glass with patterns on one side.
Multi-roller method: This method is often used in the production of microcrystalline glass and involves additional third and fourth rollers to assist in shaping.
Etching process
Although etching can also be used to create patterns on glass, it is a different process from the rolling method. The etching process typically uses corrosive solutions like hydrofluoric acid to chemically etch patterns or designs onto the surface of the glass.
However, this process is not commonly used in the production of embossed glass because the rolling method better meets the needs for mass production and cost control.
Other processes
In addition to the rolling method and etching process, there are other methods to create patterns on glass. For example, grinding can use abrasives like diamond powder to create fine bumps on the surface of the glass, resulting in a frosted appearance.
Additionally, there are methods such as spray-patterned glass and milk-patterned glass that form alternating transparent and opaque patterns through steps like applying patterns to the surface of the glass, applying protective layers, sandblasting, or chemical treatment.
In summary, embossed glass is not entirely produced through etching processes but is primarily made using the rolling method. At the same time, depending on specific needs and process characteristics, other methods such as grinding, spraying patterns, and milk patterns can also be chosen to produce different types of patterned glass.
