The Other Side of the Glass: edge profiles


As I promised, I will be discussing glass edge profiles or hasa in Filipino. Edging is very important to glass, why? Because it protects our hand and some machines from sharp edges. It also gives a classic look to the glass. Some edge profiles are flat edge polished (FEP), rough arrised, pencil edge, bevelled, half bull-nose, ogee, and miter. Please click here for some pictures for you to be familiarized.

Flat edge polished:

I think this is the most popular among edge profiles. It is simple, clean and produce a fine polished edge. It is typically applied to the glass and mirror with thickness of 4-19mm..

Rough arrised:

This is another simple and cheap polishing where the glass sharp edges taken away leaving a rough, and whitish arrised edge. This can be done to 3 to 19 mm. It can also be applied to mirror edges.

Pencil edge

This edgework has an aesthetic appeal as it gives a soft look to glass edge. As the name implies, it has a radius edge that is similar to pencil. This design is best for round or oval shapes. You can also make a layer of PE, which is called double and triple PE (or waterfall).

Half bull nose

It has a rounded upper edge similar to the top half of pencil edge. This design is best for thick glass like 10mm.

Ogee

This is an elegant design you can have for your thick glass. It has a ground and polished look that resembles the letter “S” shape. It is commonly applied to thick glass.

Bevel

This is a common decoration for glass and mirrors, where the finishing flat glass edge has a chamfered edge. This is usually done to glass and mirror with a minimum of 3 mm thickness. Bevel size can be from 1/4” to 2”. Some glass fabricators can do double and triple bevel edges.

V-cut

This is a machine beveled edge that can vary anywhere between 0 degrees and 45 degrees.


Aside from edge profiles, glass can also be drilled. You can have a hole as big as your head or as small as your nostrils .You can also make notches, grooves, and cut-outs to the glass. These will depend on the capability of the machine, the size and thickness of the glass. After hole drilling, you can choose to countersink it or not.
