PATTERNED GLASS
Level 1 Transparent
This glass is clear with very slight, if any distortion of the image viewed through it. However, it has considerable character derived from the irregularities within and upon the surface of the glass.
Level 2 Minimally Obscure
This glass is essentially clear with a surface irregularity that somewhat distorts the image behind it. As with the Level I glass, it also has considerable character derived from the irregularities within and upon the surface of the glass. This glass would be inappropriate for privacy applications.
Level 3 Moderately Obscure
The texture of this glass is its predominate feature and it provides a moderate level of obscurity. It could be considered appropriate for semi-privacy applications where the viewer or the subject was at a significant distance from the glass.
