All VILLI products are manufactured in a newly developed, patented process, which gives them a unique brilliance and interplay of light and colour.

In this process, a mixture of glass powder and pigments which are resistant to high temperatures is applied to 8mm thick float glass and fused in the furnace at temperatures of around 820˚C. This industrial production process gives rise to a homogeneous semi-finished product which is resistant to corrosion, temperature and light. VILLI processes are partly mechanically and partly done by hand.

The glass thickness of 8mm and different formats make VILLI tiles fully compatible with ceramic tiles. Working with tiles from VILLI requires ordinary tools. The complete product range covers 16 formats and 40 basic colours, but special colours are on request.
