this is the first of 3 articles that will increase your knowledge
about quality glass beadmaking and help you learn what glass
lampworking is and in the next articles direct you to where to buy
for your handmade jewelry designs by introducing you to the work of
amazing glass artists and why self representing artists are the way
to go. But why is this important?
There is an astounding amount of mass produced glass out there,
knowing what to look for will help you locate artisan quality
lampwork bead supplies for your handmade jewelry designs. This
article will also provide you with a starting place to learn about

Here are the answers you will need to understand when to buy
handmade lampwork glass beads and how to find lampwork bead
artists!
What is glass lampworking? Basically it is using a gas-fueled torch
to melt glass rods. Throughout history, there has been glass
lampworking, a type of glassblowing, or 'flameworking ' as it is
now known, since most glass artists use gas fueled torches which
mix oxygen or air as the oxidizer. This oxidation process increases
the heat produced by the torch. In ancient times, the use of an oil
lamp was used to heat the glass to a molten state, which was then
shaped with tools and formed into beads and other art pieces.
A lampwork bead artist will often purchase similar types of glass,
i.e. soft glass or hard glass, bead release, a torch and a kiln as
the lampwork supplies to make handmade lampwork glass beads. The
glass artisan will prep stainless steel rods, or mandrels, anywhere
from 1/32 to 1/8 inch diameter or larger, by coating one end of the
rod with a (clay based) bead releasing agent of some sort.
Next, the lampwork bead artist uses a torch to carefully introduce
the glass to the heat until it is like honey and then wraps the
material around the heated stainless steel mandrel to form the base
of the bead. The bead can then be decorated using different
materials and techniques. Once the bead is finished it typically
goes right in to a pre-heated kiln, at approximately 860 degrees up
to 1050 degrees, depending on the type of glass, for at least
several hours to begin the process of annealing. Annealing the
glass prevents it from cracking and/or shattering, due to thermal
shock.
The annealing process releases the stress created from taking the
glass from room temperature to over 1200 degrees, at which it is
molten, and allows it 's internal temperature to become uniform
where it is "heat-soaked ", allowing the release of internal stress
for a period of time. The duration of this process depends on the
thickness and type of glass used. Finally the piece is then cooled
slowly back down to room temperature. Annealed glass lampwork beads
are highly superior to glass beads which aren't annealed and thus
can crack when exposed to minor temperature changes.
After reaching room temperature, the beads are then thoroughly
cleaned of all bead release and ready for your limited edition
jewelry designs. This is one area of great concern for bead artists
as some of the releasing agents can be toxic to one 's health. Buy
annealed glass from a self representing artist, you won 't be
disappointed!
