Our standard glass is clear flat glass. As its name implies, clear glass is transparent and colorless. However, due to the inherit properties of glass, a green cast may become visible in clear glass when an object is placed part way under the glass. The part of the object under glass will appear greener. As the glass gets thicker, the density of the greenness in the glass will increase. Starphire® glass is an ultra-clear glass designed for a wide variety of commercial applications. It maintains its remarkable clarity in any thickness. Any green in the glass is virtually invisible to the human eye and objects placed under the glass appear the same in color as object not under glass.
