Born in the 80s from a deep passion for research and experimentation, Tonelli is a reality the world of design refers to, specialized in manufacturing of glass furniture and complements.
Its philosophy is based on a combination of tradition and innovation, essential elements that, combined with the passion for this extraordinary material, contribute to promote the glass culture.

More liquid than solid: that is glass.
In fact the physical structure presents more similarities to the molecular structure of liquids than that of crystalline structure of solids. Only the high viscosity distinguishing it avoids its particles to slide on one another as it happens instead in liquids.
At increased heat, opposed to what happens with metals that at a given temperature melt or freeze, glass goes through different stages of malleability, slowly softening till becoming malleable and obtaining the characteristics necessary to the function it’s meant to perform. Resistant, sturdy and therefore absolutely safe, glass can be of different thicknesses ranging from a maximum of 12-15-20mm for supporting structures to a minimum of 6-8-10 for tops and doors.
