Glass has many excellent
mechanical properties
which make it a perfect choice for structural use: high
compressive strength, good stiffness to weight ratio, good
resistance to aggressive environments and good long term
performance. |

Glass however is extremely brittle and this
brittleness poses serious
limitations in its structural use. The glass can be used for
many aspects. But the brittleness makes glass extremely
vulnerable to the presence of small defects in the surface which
in turn makes its tensile properties unreliable. A finely ground
satin like flat edge. The edges are very slightly
rounded and polished. Further,
the brittleness prevents any inelastic deformations before
failure which is usually a requirement in structural safety. No
edge work is done and the edges remain very sharp. Edge of Glass
is a working gallery specializing in blown art glass. Also, the
glass fragments that result from a break are linear and more
likely to remain in the frame. Look for tempered glass on dining
tables, television stands, and media storage towers. |

It is very important that the glass work piece and the grinding
wheel remain
cool during the
beveling operation. Beveling
may be in linear (straight line or shape patterns). Beveling is
the removal of an angled portion of glass from the perimeter or
mirror. Accordingly, cooling means is provided for directing a
cooling medium onto the grinding wheel. Such means may take the
form, for example, of an air misting device 22 or a water pump
22 (FIG. 2) (choice is optional, depending on beveling
requirements). Beveling produces a light quality attractive
edgework on glass and mirror. In case the air mister is
selected, and on-site compressed air is not available, an air
compressor 21 may be provided, for example, a constant duty, 1.5
cubic foot compressor. |

Tempered glass
is stronger than both untreated and annealed glass. When broken,
it shatters into many small fragments as opposed to large
shards. Therefore it is traditionally used in place of other
glass products in applications requiring increased strength and
reduced likelihood of injury in the event of breakage. |
