GLASS BBVRLLING.
Process by Which the Edge IL Cut Away
and Refinished.

Beveed glass is not new. but il Is now far more
extensively used than formerly. Twenty years
ago bcvcllcd mirrors were comparatively rare
now they are common. and seen in many
shapes and sizes. Bevelled plates large and
small, and both straight and bent, are used for
various other purposes. The process of glass
bcvcllng is very simple but the work calls for
skill on the part of the operators
The plate to be bcvclled goes first to the rough
ing mill, which is a sold. heavy steel wheel about
two feet and half in diameter, set horizontally
and turning at high rate Of speed The upper
face. or top of this wheel. is slightly roughcned
Suspended over the wheel is a big hopper contain
ing sand which is fed down through a spout in
such quantity may be required upon the top Of
the rough faced steel wheel The grinder holds
the plate to be ground in his hands, with tho
edge to he ground of upon the face Of the rough
ing mill; he shifts the plate along as the glass
is ground away. The expert grinder. holding a
sheet Of glass against the roughing wheel in this
manner will grind true beve with Il perfectly
straight line along its inner edge. and ne brings
the side bcvcls together with n perfectly true
angle at the corners.

From the emery wheel the plate goes to the
