The glass grinding process begins with the use of specialised abrasive tools and materials. Coarse abrasives are used to remove deep scratches and scale, while controlling the pressure and speed of grinding to avoid damage to the glass. Gradually, finer abrasives are used to smooth the surface and remove any remaining irregularities. POLIRO craftsmen, when removing deep scale, start grinding with silicon carbide abrasive wheels with P40 grit, called grit wheels. This is a serious process that requires professional skills and knowledge of abrasives. If you have some familiarity with the different types of abrasives, you realise how serious it is.
After the grinding process is completed, the glass is polished. Here we use our own polishing compounds: HEAVY CRYSTAL or POLIRO M8, which give the glass a smooth and shiny surface. Polishing also helps to eliminate small scratches and leave the glass without visible traces of treatment.
