When it comes to edge color for glass, some things are never as clear as they appear in the showroom. When you order glass for a shower enclosure, the edge color gradually changes according to the thickness and overall dimensions of the glass. Look at the edge of almost any piece of standard clear furniture glass and you’ll notice a green cast. That effect is exaggerated as the glass becomes thicker or longer. This phenomenon is demonstrated by the chart below, which shows how the greenish hue of conventional clear glass becomes increasingly dark as the length or the thickness of the glass grows. In addition to getting darker as it gets thicker, edge color may also be affected by other factors, such as the amount of ambient lighting or the way a shaped edge is contoured.
