Glass Clarity Options


Chiaro™ - Standard Clear Glass or Luminoso™ - Low Iron Ultra Clear Glass

At Vitrazza® we're pioneering design options for our customers. We think a Glass Chair Mat is an exceptional improvement over plastic chair mats, even when going with just our Standard Clear Glass which we call 'Chiaro' (Italian!). And now we're proud to offer an even more impressive look when customers choose 'Luminoso', our low Iron Ultra Clear glass option. See the difference below.

This first image is Chiaro - Standard Clear. Definitely clear, but with a slight tint.

This image is Luminoso - Low Iron Ultra Clear. More clarity and brighter edges.

Luminoso is 'Low Iron Ultra Clear' glass. Manufacturers have found that reducing the iron and using varied raw materials formulas increases light transmission and reduces the greenish tint in clear glass that is most apparent when viewed from the edge. The result is ultra clear, almost sparkling clear glass! If it's not low iron, it's not ultra clear, so be sure to clarify when you compare.

If you're looking for a bright, bold look in a highly visible office, Luminoso will look fantastic. Or if you have light colored floors - wood or carpet - Luminoso ensures that the color comes through without the green tint.

Whether you choose the Chiaro or Luminoso option for your Glass Chair Mat, you're still getting our trademarked Tufver™ Glass, which is 'toughened' (heat-treated) for strength and protected with our nano-tech sealer to resist scratching. There is no difference in performance!

You can order stock sizes from our Prima Collection™ or Moda Collection™, and you'll have the option to choose either Chiaro or Luminoso on each unit. If you're interested in custom sizes or shapes, we offer our Vista Collection™. We can quote those for either Chiaro, Luminoso or both. Send us an email to or call 1.800.711.8261.
