Glass is a material made of silicon with a high resistance to staining and limestone. It also undergoes a process during which it is hardened, becoming up to five times more resistant than traditional glass.
It can be polished or opaque (through a sandblasting process) and lacquered in different available colours. It is generally applied onto a lacquered panel of the same colour or onto an aluminium frame.
For cleaning, simply use water or specific neutral products. It is not advisable to use abrasive substances and tools, even in case of persistent stains.
