I’ve been a teacher of hot-glass since the Spring of 2010. I’ve been a teacher of warm-glass since the Winter of 2009. The last time I took a hands-on course was in the Fall of 2008. NOW I’m finally back into a class where I’m NOT the instructor! This is VERY exciting for me!
About a week ago, I began a course in “Advanced Sculptural Glass” at the Nova Scotia Centre for Craft and Design (NSCCD). While I’ve been making Glass Faery Ladies since the summer of 2006, and they are technically sculptural, that’s as advanced as I was able get in Soft Glass (sometimes referred to as soda-lime glass, with a C.O.E. of 104). Other beads artists experience in both soft-glass and borosilicate glass thought I was crazy to use glass that so easily thermal shocks, but I couldn’t help myself! Plus, I thought that my gear in my studios (a Nortel Minor Bench Burner running on a single 5 litre per minute oxygen concentrator) was not powerful enough to work with borosilicate (hard glass, with a C.O.E. of 33), but it turns out that I was mostly mistaken!
I say mostly mistaken, on purpose. While my studio set-up is fine for working the clear glass, it’s not so great with the colours, specifically the Reducing Colours. Because I need to crank the propane to get the flame hot enough to work the boro, I simply do not have enough “juice” from the single (5lmp) oxygen concentrator to have a neutral flame, and definitely not enough to even come close to an oxidising flame. Basically, I’m running a “reduction flame” almost constantly, which means that I’m not getting the colours I’d like in my work, and am ending up with over-struck glass, which pretty much means that icky sickly yellow.
The solution? An additional oxygen concentrator, of at least 5lpm. 🙂
That’s right folks! This is not a wishful “someday” plan, but one which will most hopefully be executed within the month. I’ll do my best to keep you posted.
Peace and Love,

p.s. Here’s a little sample of my first boro attempts (after just one class!) There’s a group shot to start, and then a marble that I’m calling “Brain Stem”, a few little vases, a nice Flower Implosion and a decently sized Clear Glass Ornament! Enjoy! XOX!
