Hi Tony,
Glass beads are made with a torch, the process is called
‘flameworking’ . A 3/32" stainless steel rod , about 9" long, is
coated on the end , about 2" long, with bead release. This allows the
glass to be melted and not stick to the metal. The stained glass is
then cut into strips, and melted in a propane and oxygen flame, or a
Mapp Gas flame depending on your torch, and as it melts, is deposited
on the bead release. The bead can be shaped with graphite paddel
called a marving paddle, into round, oblong, square shapes. Didymium
glasses are worn in able to ‘see through’ the soda flare when heating
the glass. After the bead is formed, it is then placed in a kiln at
970 degrees and let cool off at about 100 degrees per hour to anneal,
other wise, as it cools, it cracks. After it is cooled, it can be
removed from the stainless steel rod by soaking it in water. Fuseing:
If more than one color glass is to be used, the two glasses which are
fused together need to be compatible. By compatible, I mean they need
to have the same C.O.E. (Coefficient Of Expansion). There are several
type of glass that are sold for this prupose. BullsEye, (COE of 90) ,
Moretti, Pyrex, Spectrum, all have different COE’s. You would buy all
the colors in one type, and they will either fuse together (in a kiln)
or melt together in a flame, and cool off without cracking. If the
two glasses are not compatible, they crack after cooling, whether they
are annealed or not. Here are some links to glass bead supplies and
classes. I personally like the style and technique of Karen and David
at Hot Glass Beads. http://www.hotglassbeads.com

like a lot and if you dont want to buy all the equipment to get
started, you can either buy the beads on the Web, or if you dont need
to many, contact me offline, send me the glass and I’ll make them for
you.
Love and God Bless
