RARE EARTHS

In addition to the finest, purest raw materials used to produce Barberini glass, rare earths can be added to improve contrast enhancement and color perception by fundamentally changing the hue of the glass itself. 
Oxides gathered from the earth’s crust are carefully incorporated into the melt to precisely change light absorption and determine the tint of the glass. 

Benefits :
