The width of the bevel can be specified in 1/4" increments from 1/2" inch to 1-1/2" inches. The most popular bevel size is 1 inch, which is the size of the bevel in the photograph below.
Double Beveled Edge
The double bevel is a bevel on top of a bevel. A 1" double bevel specifies an edge with the first bevel 1" wide, and a narrower bevel on top of the first that is approximately 1/2" wide.
Flat Polished Edge
A flat polished edge is one of the most economical edges, and by far the most popular edge for glass shelves thicker than 1/4". Where the edge meets the top and bottom surfaces there is a small miter, which can easily be seen in the sketch. This is actually called an arris, and a flat polished edge always includes arrises.
An ogee edge has rounded edges and a style that is very popular with traditional wood furniture and modern solid surface countertops.
Double Waterfall Edge
To produce this edge the glass is slowly chipped by hand all around the perimeter. Then the edges are sandblasted, which removes all the sharp edges and produces a rather smooth frosted edge.
45° Mitered (or Chamfered) Edge
Similar to a beveled edge, but at a 45° angle and usually half the width. As with a beveled edge, the remaining portion of the edge has a flat polish.
Pencil Polished Edge
Chipped and Sandblasted Edge
This is a bullnose edge with a 1/4" radius. The "soft" edge provides more comfort than some of the other edges.
