Every year since 1997 I've been driving to Haliburton, Ontario (a little village about an hour north of Peterborough and just on the southernmost border of Algonquin Park) for my week-long getaway at the Haliburton School of the Arts. Yes, going to Art school for six and a half hours a day, five days in a row is my idea of a vacation. I love it!
This year I was originally registered for a Business for Artists course. I was really looking forward to it as it was going to discuss tricks and tips for grant writing (my next thing to attack!). However, it got cancelled due to low registration. So I signed up for glass beadmaking instead and had a ball.
Glass beadmaking involves melting rods of differently coloured glass in the flame of a torch, winding the molten glass rods around a stainless steel stick and using the flame to make various shapes. Here's a shot of my work surface with the torch, some glass rods, shaping tools, stainless steel buckets of water for scrap and those stainless steel winding rods (the things that look like unlit sparklers – the gray stuff is called bead release and allows you to slip the bead off the winding rod once it has cooled down. Without bead release, you can't get the bead off and you end up with a nice plant stick – hee hee!
Here are my beads from the first day – looks like a bouquet, doesn't it? The red tips are so I can tell my beads from the beads of others. All the beads, once completed, go into a kiln (a really hot oven) to cool down slowly to room temperature to avoid thermal shock and cracking. Confusion and inadvertent bead theft can occur without the marking.
There are two main kinds of glass in bead making, commonly referred to as “soft glass” and “hard glass”. Melting temperature is lower for soft glass, and the colour you see in glass rod form is what you will get once you're done forming the bead in the torch. However, soft glass is more sensitive to changes in temperature (and more prone to cracking if you're not careful to keep it evenly warm while you're working).
The hard glass is called borosilicate glass and is the same stuff Pyrex bakeware and scientific test tubes are made with. It has a higher melt temperature and is much less prone to cracking because of uneven warming, so you can make more complicated things. My instructor, Brad Sherwood, makes these really cool glass marionettes out of this glass, with jointed jaws and limbs. The other cool thing about borosilicate glass is the colour variations you can get out of the glass by varying the heat applied to your bead.
Here is a beautiful pendant and matching tiny beads I made on my last day of class. Those tiny beads have fantastic swirls of colours and hints of metallic tinting. They didn't go into the kiln at all – their small size allowed me to prop them up on my tabletop to air cool with no ill effects. And I got all fancy when I was winding them on the stainless steel rods – instead of only one bead per rod, I wound four or five to each rod, creating quantities of beads in a very short time.
As you can see, I had great fun, as usual. I highly recommend this art school. Haliburton is able to attract excellent instuctors, and their course catalogue is large and varied. So go create!
