Transparency Values Explained - Understanding Transparency Values can play an important roll for proper glass selection

• Transparency of Glass is measured by Level of Opacity. It is a measure of how much visible light or how little visible light can pass through a piece of glass.
• Levels of Transparency start with Transparent (most visible light) and gradually increase in Opacity to the most obscure Opalescent (least visible light).

Transparent - 100% Transparent glass, Visible light can easily pass through, do not contain any opaque glass or other light blocking material. Commonly referred to as Cathedral Glass.

Translucent - Predominantly Transparent glass with some mixed in Opaque glass, allowing light to pass through in many or most areas.

Semi-Translucent - Predominantly Opaque glass with some Translucent glass mixed in, allowing less visible light to pass through or pass through only in small areas.

Opalescent - Glasses that are primarily or completely opaque, blocking direct visible light while retaining color when back lit.
