A hand-blown glass bead is a beautiful piece of craftsmanship. Vibrant
colors fire-polished to a shiny surface or tumbled for days in a rock-tumbler
to give a soft, sand-blasted appearance make up Lisa's beads. The finished
product of a shiny or tumbled bead takes considerable amount of glass,
time and patience as you'll see below.

Here Lisa gathers some glass on the end of a blow pipe. |
 |
After letting the molten glass cool for a minute, she goes in
for another gather. A hole is blown in the center of the glass. |
 |
Crushed colored glass, also known as frit sits in a scoop. |
 |
Lisa rolls the molten clear glass in the frit to apply color to
the outside of the glass on the pipe. She may go in to the furnace
for several more clear glass gathers. |
 |
Lisa heats (and melts) the glass in the glory hole which is typically
above 2000 degrees farenhiet internal temperature. |
 |
Lisa uses the marver table to shape the bead. The marver table
is made of 1 inch thick steel. |
 |
Lisa goes back to the marver table after heating the bead in the
glory hole again, to make it pliable. |
|
|
Lisa shapes the bead with her hand under wet newspaper. The wet
newspaper gives enough of a barrier against the heat, although the
newspaper does need to be re-wet periodically. |
 |
Her assistant creates a pancake of glass on another pipe that
will be used to attach to the other end of the bead. |
 |
Lisa heats up the large bead until it is nice and "juicy."
She has her assistant get the 'pancake of glass' ready and she attaches
the bead to the center of the foot. The bead is now attached to
pipes on both sides. |
 |
The tug of war begins! |
|
|
The glass has to be pulled at a constant, even speed and sometimes
rotated to ensure the glass doesn't get too thin at a particular
point or hit the ground prematurely. |
 |
Lisa starts putting some weight behind the bead pull
as the glass starts to cool and get more stiff. |
|
|
While the glass is still almost 1000 degrees farenheit, the bead
is cut into 2 foot sections and placed into an annealler to cool
slowly overnight.
If the thicker ends are the right size and have a large hole
down the center, they may be used for creating a lamp base. It
is rare to get a nice-enough piece for creating a lamp.
|
 |
After at least 24 hours of cooling, the bead rods can be cut into
smaller sections. |
 |
The bead sections are then cut into the final size beads. Some
beads split/crack during this process due to thin sides, heat
from the saw or other reasons.
At this stage, the beads have two rough edges.

A bucket of cut and washed beads. They are ready for the next
step. |
 |
The beads are then lined up according to size, thickness, and
height on a high-temperature kiln shelf.
They will be brought up to a temperature of over 1000 degrees
farenhiet, then torched using a propane torch to melt and polish
the beads to their final luster. After the beads cool slowly,
they will be turned over and the beads are torched on the final
side.

 |
Here is an example of some of the finished product as bracelets.

After the beads are cool, Lisa then has to pick which beads are bead-worthy.
Sometimes the holes in the beads close up from too much torch heat.
Sometimes there is an imperfection like a bubble, scratch or uneven
surface. It is estimated that about 50-60% of the original bead is actually
usable for jewelry after all the steps are complete.
