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%). (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. 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 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
Ultra Clear and durable glass
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. 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.
