Glass etching / matting
Glass etching and glass matting are the chemical treatments those are intended for achieving a change in visual and surface properties of glass objects. It is mainly used for a forming of glass abrasive surfaces for different purposes as a replacement for common abrading materials (metal, diamond). But it can be also instrumental to produce matt surfaces for decorative and other functional usage. This chemical process is so specific for different glass objects and therefore there are many factors and circumstances those can affect the final appearance and etching quality. Glass chemical content, treatment time, operating temperature and acid mixture concentration belong to the most important ones. Different types of glass require different approaches and the optimal etching parameters can be determined only empirically. This method is suitable all above for Sodium-Calcium glasses. Barta a Cihlar company has been concerned with glass etching and matting for many years. That is why we can offer a personal approach and assist to find the best way to achieve your requirements following our plentiful experience and work history.
Layer properties
- Matt appearance - for decorative and functional purposes
- Abrasive surface - abrading material processing
Deposition - dimension
- 50 - 100 μm - abrasive (abrading) materials
- < 10 μm - matt materials
Way of processing
- Rack
- Free immersion - glass tables in cartridges
Basic material - substrate:
- Sodium-Calcium glasses
Application field:
- Decorative - glass packaging, bowls, glasses, bottles etc.
- Abrasive sufaces - alternative for metal and diamond abrading materials
- Optical facilities - production of light scattering items for passage of light - softening and area homogenization of point-source light.
