All of my glass beads are
handmade (by me!) The process of working with hot glass on a torch is called
Lampworking - the name comes from Italy, where before Modern Technology
kicked in, the early glassworkers made their beads using oil lamps and
foot bellows as a heat source. |

Most of my beads are made on a
table-top Bethlehem Starfire surface mix oxygen propane torch. I've used it for
nine years now, and like it a lot... and NOT just because it has cooling
fins like a ray gun, and wheels on each side so I can whiz the barrel up & down like a
Death Star laser cannon, BBQ'ing unlucky bugs in the summertime - fun!
I work with the torch angled sideways to the left so I can see the entire
length of the flame - makes it a lot easier to control heat, and I can
always tell exactly where I'm working in the flame. |

When the eyeballs and bellybuttons are on and the bead is
complete, I stick it in my annealing kiln at 970 degrees. That's in
the annealing temperature range for Effetre glass - other types of glass anneal at
different temperatures. The bead needs to soak at 970 for a minimum of 30 minutes,
longer for larger pieces; this removes all the internal stresses so the
glass won't crack
later. What I usually do is leave the kiln on all day (you don't *WANT* to see my
electric bill...), then start the cool-down cycle after the last bead has
had a good soak. When I'm done the computer controller is programmed
to lower the kiln
slowly to room temperature - it usually takes about 4 hours. Then the beads can
be removed from the mandrel, cleaned, and presto! Theyre ready to join their buddies
in the drawer, waiting for the next big show. |

These are rods of Effetre glass, imported from Murano, Italy (a
lovely 20 minute vaporetto ride across the bay from Venice...give it a try sometime!).
Pretty, eh? The glass, along with kilns, torches, and tools, can be had from
a number of suppliers these days... Arrow Springs, Frantz Art Glass, Ed Hoy
International, and C&R Loo are my primary suppliers. The rods come in 3' lengths of various thickness,
in lots of opaque, transparent and translucent colors. There are also other types of glass
available, with different melting and annealing points, colors, and working properties:
borosilicate (Pyrex), Bullseye, Satake from Japan, and rods from Germany &
Czechoslovakia. In most cases, the different kinds of glass are compatible within
their own group, but not with other types of glass (ie, you can't mix Bullseye and
Effetre, because the beads will crack as the different types of glass cool and contract at
different rates). |

These are some of the tools I use to make beads. From the top:
graphite and small brass paddles for shaping; a striker for lighting the torch;
tile nippers for cutting glass rods; and a small pair of mashing pliers, for making flat
disk beads and mammogram beads (good for Squash Blossom necklaces). My
really big masher, the Husband Chaser, didn't fit on the scanner, darnitall. |

More tools: three tungsten picks, for pulling, raking, and feathering
designs, and poking nose holes, bellybuttons, and other (censored) anatomical
features; A Utility Blade shaper used for pushing, notching,
and moving hot glass around for sculpting; a flat dental tool for shaping;
pointy-tipped tweezers for plucking out air bubbles & scum; a hemostat modified
to hold hot pieces of rod; Hot Fingers to manipulate hot pieces in the flame or
kiln; and another tweezer. |

And still
more
tools (I really don't need
them all, I'm just stockpiling everything in sight for the
Apocalypse): a
jar of frit - little bitty chunks of glass to roll onto a hot bead for color
variations; a fancy marble mold; pointy-nosed pliers for pulling out fish
fins; a jar of green pixie dust - roll the bead in this for a soft luster
finish;
a round file for texturing; chunks of goldstone for sparkle; imported
millefiori chips for pattern; another masher because I forgot there was one in the
first picture; and my didymium glasses, which filter out the red glare & UV when
I'm working glass in the flame. All beadmakers look like Austin Powers in these. |

So you have torch, kiln, and tools;
you've bought the books, watched the videos, taken the class, and are ready to make
a bead. The first thing you do is coat the end of a stainless steel rod (called a
mandrel) with bead release, thin clay-like goop that keeps the glass and the metal
separate during the beadmaking process. If the bead release breaks, or the hot glass
touches the metal, the bead will be stuck on the mandrel until ...until... what's longer
than 'Hell Freezes Over'? Until I wake up in the morning and say "What a nice
day to clean the house!!" Yep, that's it. Anyway, Ive got lots of
these dead bead/mandrel thingies... they're great to stick in planters, and if I ever
decide to become a geisha they'll look great in my hair. And I'm already memorizing
appropriate phrases... "Hyakuoku-yen, risoku yon-pasento de kashite
moraemasuka?" |
