Lightness
represents the glass capability to let the light go through, basically it measures the glass transparency.
Lightness values superior to 98.8 guarantee an excellent transparency.
Chroma
Ultra Clear and durable glass
represents the glass purity, basically it measures the degree of colourless.
Chroma values inferior to 0.5 do not modify the real colour of the liquid contained.
Iron oxide
Luigi Bormioli Research Team by means
of spectrophotometric measures has
obtained this new glass outstandingly
transparent and sparkling.
The outcoming measures are extremely
in line with the consumers perception
of quality and transparence.
(unavoidably present in glass) inferior to 140 ppm prevents unsightly colourings such as green/blue -
green/yellow. This is achieved by employing only the purest of raw materials and an extremely close
production process control.
Compliance to all 3 above mentioned values results in an Ultra Clear glass with a high colour
efficiency (R) of the liquid contained (R>99.99%).

This new material has an extremely low iron content
so that it does not interfere with both the transparency
and the colorimetric purity of glass. Furthermore,
is lead and other heavy metal free. is classified
Ultra Clear according to ISO/PAS IWA 8:2009.
