Is It Better To
Use a Glass Bandsaw
The Advantages:
- Using the bandsaw
will make difficult to near impossible cuts very simple.
- Cutting dense
ripples and drapery glass is a piece of cake.
- Due to the bandsaw's
accuracy, considerable time is saved.
The Disadvantages:
- A bandsaw is
limited to the size of a piece that you can cut, because of the circular
bandsaw blade. With most saws a piece of glass approximately 10"-12" may
be cut in half.
- A bandsaw does
not take the place of simple cuts. It's much faster and practical
to cut strips, straight lines and simple shapes using a regular glass
cutter.
- While using the
bandsaw, cuts may be made that are structurally unsound and susceptible
to cracking.
How
Do I Check My Glass Cutter For A Chipped Wheel
A chip on the wheel
of a glass cutter may not be discernible to the naked eye. To determine
if this is the case, score the glass side of a piece of mirror, but
don't break it. Since the silvering on regular mirror is on the back
side of the glass, it will better reflect and illuminate the score
line. Examine your score. Does the score look like a dashed line? If
the answer is yes, the cutter wheel is indeed chipped and will affect
any glass cutting you do regardless of the type of glass and must be
replaced.
How
Can I Effectively Work With Patterns
When you are working
with patterns, it is good to know that some stained glass patterns
will come full-sized and others need to be enlarged. We recommend making
two copies of your pattern and keep the original for future projects.
- Number the pattern
pieces on both copies, add arrows to show "streak" or "texture" direction,
indicate glass color or other helpful notes on each piece.
- Use one copy for
pattern pieces and the other for layout / assembly. Make your lead
lines with a fine point sharpie pen. For foil use an extra fine point
sharpie pen.
- When using bevels
and / or bevel cluster, always draw around each bevel as though it
were a cut piece of glass and number it to correspond to the place
on the pattern as they are hand cut and vary in size and shape. This
will make your background pieces fit much better.
How
Do I Cut Front Surface Mirror
Front
surface mirror, which is used in kaleidoscopes, is a hard yet brittle
glass. Here's how you can successfully cut it.
- Use a cutter with
a carbide wheel that is going to be strictly used for cutting mirror.
Do not use it on other glass so that the wheel will stay sharp and
unchipped.
- Cut the mirror
on a firm surface which is covered with a thin layer of felt or very
thin cardboard. Score lightly and then break the glass gently. Straight
scores are more successful when the cutter is pulled toward your
body.
- The blue plastic
coating on the front of the mirror should still be attached to the
glass. Being careful not to grind the edges of the glass together
and use a sharp blade to cut through the plastic at the break line.
- For a good score,
it is important to hold the glass cutter perpendicular to the glass
while applying light, even pressure. If the cutter strays from this
angle, it is possible for the glass to jump off of the score. Leave
the blue film on the glass for protection until you are ready to
use the mirror.
How
To Get Your Solder and Lead Seams Bright and Shiny
Occasionally
you will see a stained glass piece or suncatcher which seems to have
a very bright, shiny appearance on the solder or lead seams. The piece
has been plated by use of an electroplating technique. Plating is a
process where a finished glass project, either lead or copper foil,
is dipped into a vat containing a chemical solution with metal particles
in it. An electrically charged source is attached to a soldered portion
of the finished glass piece which draws the metal particles in the
chemical solution onto the solder seams. To protect the metallic coating,
a clear lacquer is also applied, which also gives a bright and shiny
finish. Both chrome or brass plating are often used. Mirror or iridescent
glass should not be used on pieces to be electroplated as the metals
stick to the mirror and iridescence causing an unpleasant look. Due
to the nature of the chemicals and equipment used, this process should
be left to the plating professionals. Look in your phone book under "Plating" or "Electroplating" for
companies near you.
How
To Apply Filigree
Hold
the filigree with pliers or a clamp, as it will get quite hot, and
coat it liberally with flux. Holding the filigree at approximately
a 45 degree angle and lightly coat it with solder. Let the solder drip
off of the filigree and make sure that all holes are free of solder.
Place a container underneath so that it can catch the drips. Be aware
that it may splash. After tinning the front side, turn it over, and
reapply the flux and solder. If the solder starts to gum up or get
dirty, wipe off the tip of your iron and re-flux. Before attaching
the filigree, wash the filigree thoroughly with CJ's Flux and Patina
Remover or another suitable cleaner and pat dry.
How
do I Make My Patinas Look Great
- To achieve the
best results with patinas, first clean the solder seams thoroughly.
Next, wash your piece with a flux and patina remover and warm water.
- Dry it off and
apply the patina. It's a good idea to wear rubber gloves while using
patina so that it does not irritate your skin.
- Apply the patina
to the solder seams using a Q-tip, cottonball or gauze.
- Let it dry for
a few minutes, rinse the entire piece with warm water, then pat dry.
Examine the solder seams. Does the finish look satisfactory? If not,
add a pinch of salt to the patina solution and reapply it to the
seams.
- After this process
is completed, polish it with finishing compound, carnuba wax, to
both polish and protect the glass and solder seams.
Finishing compound
leaves a protective film which will help slow down the oxidation process,
but won't stop it completely. Oxidation occurs as air particles react
with metal surfaces. Gradually over time all metals will turn black
and have a dull finish. It's a natural process. The only way to prevent
this is to wax and polish your pieces regularly. If you have a piece
that is highly oxidized use extremely fine steel wool to clean the
solder seams then re-patina the piece. This works very well. The smother
the solder seams are the better the patina will look. With Copper Patina
it is a little more important to make sure all the oxidation is cleaned
off the solder before applying the patina. The best way to do this
is to clean the solder with finishing compound both before and after
applying the patina.
