GLASS EDGEWORK:

When glass is cut to size, the edges are very sharp unless some kind of edgework is requested. The roughest form of edgework is a seamed edge. Seaming the edges is mearly removing the sharp edges and minor irregularities in the cut edge. This simple form of edgework makes the glass safer to handle, fit more securely in its frame, and is most appropriate for glass that will be framed on all sides.

One of the most beautiful ways to finish glass is by polishing the edges. Glass can be custom manufactured to include edgework of all kinds. Glass that does not contain any edgework is often refered to as-no edgework-and the glass edges are unfinished and very sharp. If a client orders the glass "seamed", the sharp edge is removed from the edges of the glass, making the glass more user friendly for handling.

Fine edgework is accomplished either through the use of beveling machines or done by hand depending on the type of edgework being performed on the type of shape of glass. The most common type of edgework is beveled, in either 1/2", 3/4" or 1" sized bevels. The second most common type of glass edgework is Flat Polished Edges, or FPE, which is a machine polished edge with a high polish and mitred corners. There are also many specialty edgeworks available: large bevels of 2" or more, a pencil polish which is a round bull-nose effect, or waterfall edgework which is a multi-layered bevel that cascades over the edges of the glass.

Glass with finished edgework can be created into or from safety glass types
