- Step 1. Circles can be scored
freehand or with a circle cutter. First, score the
circle, making sure that you start and stop the score
line at the same point.
- Step 2. Turn the glass over
onto a piece of corrugated cardboard with the score line
face down. With your fingers, press along the score line
until you see the score line "runs" completely
around the circle.
- Step 3. Turn the glass over to
the side on which you scored it. Score several tangent
cuts off the circle.
- Step 4. Break these tangential
scores with your hands, pliers, or the Morton System. The
circle should break out clean with no rough or jagged
The most difficult concave curves can be
made easy making only one score line, if you are using the Morton
System. To accomplish this by using the hand breaking method
and/or plier method, you must first make a series of concentric
Then remove these graduated scores in
sequence. Gently tap out the primary score last.
You can also accomplish this type of cut by
using the crisscross pattern of score lines instead of concentric
REFINING ROUGH CUTS AND SHARP EDGES
After the glass is scored and broken, you
can remove small unwanted chips with grozing pliers. The
serrated jaws of these pliers are used to gently nibble away at
the jagged edges.
Rough edges can also be smoothed with a
carborundum stone or one of the sophisticated glass routers,
which have recently become an affordable item for the hobbyist.
Many models of routers are available. The grinding surface is
covered with fine diamond industrial chips, which grind away
unwanted glass very quickly without chipping the edges. In
addition, they are water-fed which keeps the glass from cracking
due to heat, prolongs the life of the diamond bit, and prevents
the powdery ground glass form flying around.
