| EFFECTS IN GLASS GLIDING Two
Tone Gilding
Chalk or pounce the layout as usual.
Then lay the XX Deep gold with water size and back-up in
outline only. Clean off superfluous gold with cotton
saturated with whiting and water. Fill in the centers of
the lettering with a mixture of quick rubbing varnish and
turpentine. If applied thin, it will tack up quickly. Now
gild the centers with either Lemon or Pale gold, direct
from the book as in surface gilding, by laying the gold
right into the tacky varnish center. The lettering may
now be outlined or shaded with color if desired.
However, many high-class jobs are plain
two-tone letters with no outline or shade. Where you use
no outline or shade, it is best to paint the back of
letters with aluminum or bronze mixed with varnish. When
dry, varnish the whole job carefully with a good outside
spar or coach finishing varnish. Instead of Lemon or Pale
gold for the centers, many sign men prefer to use XX Deep
gold. The varnish will prevent XX Deep gold from
burnishing while the outline will have its usual
brilliant burnish. Imitation
Embossing or Mat Gold Finish
This is one of the most striking
effects that can be obtained but it takes somewhat longer
to do. You pounce the layout in the usual manner, gild
the job and burnish it. You back-up only in outline all
parts of the lettering, scrolls or designs that are to be
embossed. When backing is dry, remove superfluous gold by
cleaning in the usual manner. This leaves the parts to be
embossed clear glass. Fill in the centers with Damar
varnish to which a few drops of quick rubbing varnish
have been added.
Because Damar varnish sets very
quickly, but never dries very hard, the addition of quick
rubbing varnish helps to make the Damar dry hard at the
same time keeps your backing-up color from cracking. As
soon as the varnish shows a strong tack it is ready for
stippling. Stipple with the stub of a bristle brush or
with a stippling brush. The brush may be held at an exact
right angle to the varnished surface. Continue this
stippling until varnish shows the desired embossed
effect.
When the varnish is dry (and that will
take quite some time because of the slow drying qualities
of Damar), water size, regild and finish as usual. For
this second gilding you can use XX Deep gold, but Lemon
or Pale gold will heighten the embossed effect. Do not
use a quick drying color for backing-up where Damar has
been used, as a quick drying color or may have a tendency
to crack the lettering.
Pock Marking
Another method used to get a rough or
pockmarked center is to brush the cleaned off centers
with Damar varnish to which a little quick rubbing
varnish has been added. Then spray water over the varnish
from an atomizer. The water will bead and will give the
varnish a rough, pockmarked effect. When gilded with Pale
gold, the centers will have a very striking appearance.
Macaroni Scroll
This very popular center is made by
mixing ten parts of Damar varnish with one part Balsam or
Fir, three parts quick rubbing varnish and a pinch of
powdered pumice. Fill in the clear centers with this
mixture. When this varnish reaches a strong tack, take a
small wooden wedge or the pointed end of a lettering
brush handle and scratch scrolls or fern like designs in
the varnish. When the varnish is thoroughly dry, water
size and gild with Lemon or Pale gold. Back-up and finish
the job in the usual manner.
Spiraled or Spun Centers XX Deep gold
is laid and backed-up in outline only. You fill in the
centers with slow oil size to which a little varnish has
been added. Allow the job to stand overnight or for
several hours. Then gild from the book as in surface
gilding, using Pale or Lemon gold.
After rubbing down the gold very
lightly with cotton, take a small piece of velvet or
chamois and with it form a ball between the fingers. Bear
down against the back of the gold with a light pressure
and twist the chamois or velvet around in a rotary
motion. Go all over the centers in this manner. (But do
not press or twist too hard. Begin lightly until you
acquire the knack of handling.) The job is then backed-up
and varnished in the usual way.
Blended Gold and Silver
Gold leaf is applied to the glass in
the ordinary manner, except that only the upper half or
three quarters of the letter is gilded. Patch and burnish
the gold as usual. To accomplish the blending use a flat
brush that has been cut down about a one-quarter inch
bristle. Draw brush across the letters, beginning at the
bottom and continuing up to about three quarters the
height of the letter. This will scratch the gold.
The lower portion of the gold should be
almost entirely removed. Reduce the pressure of the brush
as you go up to take off less and less of the gold, until
you blend into the solid gold near the top of the letter.
The object of this scratching is to give you an
opportunity to unite the gold and silver with an
imperceptible joint. You now lay silver leaf over the
lower portion of the letter and overlap all parts of the
gold that have been scratched. You then back-up and
varnish the job in the usual manner.
Glazing
For glazing gold lettering use only
transparent colors. Glazing colors should be mixed only
with high-grade, light japan and thinned until colors are
quite faint and indistinct. Apply glaze with a camel hair
brush, and when the glaze is thoroughly dry, gild with
water size in the usual manner.
PLASTER
It is of utmost importance that the
plaster be thoroughly seasoned, dry, hard and free from
alkali. It should then be first coated with a standard
make of pigmented wall primer and sealer. When this coat
is dry, slow drying oil gold size may be applied and the
leaf laid when the gold size has reached the proper tack.
Special Effects In Gliding
We have had a great many requests for
information as to how various striking and unusual
effects can be obtained in gold leaf work. The following
effects were those asked for most frequently. To avoid
repetition, it is assumed that the reader is already
familiar with the method of gilding ordinary signs: the
following descriptions, therefore, deal only with
variations and additions to usual methods by which the
effects may be obtained.
Engine Turning
Engine-turning or "swirling"
is particularly effective when a protective coat is used.
All transparent coatings detract somewhat from the
lustrous surface of the leaf; and a reflecting value, on
part of each letter on a whole line of lettering, may be
obtained by disturbing the flat surface of the leafed
portion in regular design. This is accomplished through
the use of velvet plush padded to the desired bulk with
cotton. When the surplus gold has been skewed from the
surface immediately after being laid, the plush pad is
held against the leaf and turned with a twist of the
wrist.
Successive twists should overlap, and
twists in successive lines should be staggered. Designs
and novel effects can be produced by masking out portions
of letters with paper, using the plush pads in straight
strokes on the unmasked portion. Proceed with various
angles as in cross hatching. Try this as well on contrast
mat center glass work. Apply the leaf to the tacky dead
center varnish and proceed as if you were working on gold
size. The effect will show up through the glass and
varnish from the reading side.
Gold Leaf Face Shading
This is a very striking and rich effect
and has the added merit of being easily and quickly
obtained. Just before laying the gold leaf, lay in the
shading you desire with a small pencil and clear,
quick-drying varnish. The shading may consist of
elaborate scrolls, lines, or other patterns. Add a little
burnt umber to the varnish so that you can see what you
are doing.. Or you can avoid this by pouncing lightly
with whiting. When the varnish is dry, lay the gold leaf
as usual and burnish it. The parts covered with the
varnish will remain mat, thus giving you the shading you
desire.
Cleaning Raised Wood Gilded Letters
Use nothing stronger than mild soap
suds. Apply the soapy water with a soft sponge and do not
rub so hard as to injure the surface of the leaf. Be sure
and rinse with clear water before the soapy water has had
a chance to dry. Strong solutions must be avoided as any
damage to the undercoat will kill the brilliance of the
leaf. If the soap and water treatment does not give
satisfactory results it is time to regild.
