Small Dragonfly Instructions
REUSABLE MOLDS FOR GLASS CASTING
Small Dragonflies
The Small Dragonflies with
Wing Slumper mold has been
one of the most popular designs.
Why not devote a project sheet
just to making, shaping, and
tacking these designs.
nnn
Start by cleaning the dragonfly
mold with a stiff nylon brush and
remove any old kiln wash. Then
coat the mold with four to five
thin, even coats of Hotline Primo
Primer. It is the only primer we
recommend because it doesn’t obscure the mold’s fine detail and is
easy to remove after firing. Use a
soft artist’s brush to apply the
primer and a hair dryer to completely dry each coat before applying the next. The mold should be
completely dry before filling.
Availability
Colour de Verre molds are
available at fine glass retailers
and many online merchants
including our online store,
www.colourdeverre.com.
To keep the dragonflies delicate,
use only 30 grams of frit for the
large dragonfly and 20 grams of
frit for the small dragonfly. (This is
less than the fill weight listed on
the mold’s packaging.) Additionally, the molds will be fired cooler
than the general instructions.
Weigh the mold and note its
weight. The filled mold will weigh
50 grams more.
Highlight the dragonflies’ wing
and body details by sprinkling just
enough fine Black frit into each
cavity to fill the wing veining and
the head and body. Gently tap the
mold to cause the frit to settle into
place. Sprinkle a dark, fine frit
(Pale Purple, Dark Blue, or Dark
Green) into the head and down
the body’s length. “Feather” a little of the dark, fine frit out the
dragonfly’s wings. Place the mold
on the scale and fill the wings with
a light, fine frit (Clear, Neon Orchid, Urobium Pink, or Ming
Green) until the the scale reads 50
grams more than the mold’s
empty weight. The mold’s cavities
will only be about one-half full.
Gently tap the mold to level the
surface. Place the mold or molds
in the kiln and fire according to
the following schedule:

Shaping the Dragonflies
On the mold’s reverse side is a
wing slumper. A slump firing on
this surface slightly bends the
wings up and gives the dragonflies
a much more lifelike appearance.
Start by preparing the reverse side
of the mold in the same way the
casting surface was prepared.
Place the dragonflies, textured detail side up on the slumper. Align

Adding to Other Pieces
The dragonflies can also be added
to plates, platters, and other larger
works. To tack fire the dragonflies
to the larger pieces, use the schedule below:
If you wish to tack fire dragonflies
that have been shaped, you will
need to support the wings during
the tack firing. Use a small dab of
white glue on the dragonflies’
body to hold the loose pieces in
place. Tuck small squares of kiln
paper under the wings to support
them during the firing.
Variations
Experiment with adding small,
dichroic glass shards to the wings.
Encase the shards between thin
layers of fine frit to ensure a
smooth surface.

Oval Dragonfly Lamp
The result is both beautiful and
useful: An accent lamp that fits
perfectly in your – or a friend’s –
bedroom, living room, or den.
Use this project sheet as a
starting point for creating your
own designs with your favorite
Colour de Verre castings.

Here’s the plan:
1. Create the dragonflies.
2. Tack fuse elements to the
sheet glass panels.
3. Slump – really drape – the
panels.
4. Assemble the lamp.

Frame the two panels with eight
Black noodles. (We find the easiest
way to cut the noodles is with a
mosaic tile cutter.) Glue the noodles into place with a few drops of
Aleene’s Tacky Glue. On one of
the panels arrange and lightly glue
the cast dragonflies in place. Once
the glue dries, sprinkle a layer of

One thing that can’t be stressed
enough: Don’t rush the slump firing. Between the frit, noodles, and
dragonflies there is quite a variation in the panels’ thicknesses.
They require a slow ramp and
cool down to avoid thermal shock.
Instructions to mount the panels
onto the 10” Oval Lighting
Hardware can be found in the
hardware’s box. Choose a lamp
wattage that complements the final piece.

stiff brush to stir the compacted
particles off the bottom of the
container and back into solution.
It is not necessary to pre-fire the
mold as long as the primer is dry.
After firing the mold, use
any nylon kitchen brush or
a toothbrush to remove all
traces of the primer from the
mold. We strongly recommend
wearing a dusk mask.

Tricks of the Trade
We want our customers to have
a great experience and wonderful outcomes with our molds.
Let us pass along these hints
and advice.
nnn
Use Hotline Primo
Primer. We tested many
kiln washes and primers
from a number manufactures.
Only Hotline Primo Primer offered us the three properties that
we required: thin, even coats that
don’t obscure the design; consistent release; and fired primer can
easily be removed with a stiff
brush.
1
Mix the powder with water according to the label instructions.
Apply four to five thin coats to the
mold’s inside surface. Let each
coat dry before applying the next.
A hair dryer can be used to accelerate the drying between coats.
Keep the primer well stirred. The
primer’s fine particles – the active
components – settle out of the
mixture rapidly. If the primer settles, the particles will start to cake
on the container’s bottom. Use a
Always follow the firing
schedule recommended on
our website and packaging. Colour de Verre molds are
made from a specialized ceramic
material. Like glass, this ceramic
will crack or shatter if it is heated
or cooled too fast.
3
Finished pieces will have
much smoother edges if
you use a small brush to
move the frit away from the top
edge of the mold. This “trough”
only has to be 1/8-inch wide and
deep.
4
Use only crushed art glass
or frits in Colour de Verre
molds. The molds are not
designed for Pyrex glass, float
glass, or crushed bottles. We don’t
recommend firing Colour de Verre
molds above 1500°F (815°C). At
higher temperatures, the primer
will start to fuse and becomes
more difficult to remove.
5
If the finished piece
doesn’t fall out of the
mold, don’t panic. Turn
mold face-down and tap it against
a hard surface cushioned with several layers of newsprint. If the
6
piece still doesn’t fall out, the mold
probably wasn’t properly primed.
Occasionally, a few glass
spurs might be on edges of
the finished pieces. These
are easily removed with a wet
diamond block or grinder. Following hint #4 will minimize these.
7
Butterflies, dragonflies,
flowers, and leaves can be
given more life with a second, slump firing. Some of our
designs have a specially designed
slumping surface on the reverse
side.
8
A “sugar fire” yields wonderful results with Colour
de Verre snowflakes. Fill
the mold to half of the recommended fill weight with fine frit.
Fire to a “partial fuse” – about
1300°F (705°C). This technique
can be used with any of our
molds.
9
Don’t be afraid to experiment. Add CMC solution
to your glass powders to
make a pate de verre paste. Mixed
crush dichroic with your frits. Tack
fuse finished pieces to slumped
plates and platters. Mix shredded
copper, silver, or gold foil into your
frits. Embed smaller forms inside
of larger, clear forms. The possibilities are endless.
