There are standard profiles, which actually have specific names, so that when you order a glass blank with a special profile, you know what you will have to say on your order form. If you only order prefabricated items from overseas, this may not be of interest to you. Some shapes do have limitations in that they can only be produced on round shapes, for instance, like the Ogee profile.
FE Polish: Flat Edge with Arris, standard on all rectangle squares, but can also be applied to circles and ovals of 3/4″ thickness; not available on straight line edges.
Full Pencil Edge: Standard on circles, ovals, and curved shapes of 1/2″ thickness.
Ogee Edge: Only available on circles and ovals from 3/8″ to 3/4″ thickness.
Edge #3: Usually created on 3/4″ or 1/2″ thick straight glass. The slant or bevel is almost 1″ wide and looks particularly good on a base piece.
Edge #4: Used on straight line glass only from 3/8″ to 3/4″ thick glass. This profile combines a bevel with a straight edge.
