Stained Glass Kilns and Firing Schedules

Firing stained glass is no more a science than cooking is a science: kilns vary, just as household ovens vary. But of course it matters: it matters greatly.

So the most important thing is, when you’re doing something new, you should always fire some test pieces until you get the results you want. But don’t get too precise and dogmatic about it: if you’re not making your own glass (who is?), and not making your own paints etc. (again, who is? we all buy ‘off-the-shelf), then there are always unknown variables which might – just might – affect your firing.

In other words, keep it in perspective: firing glass paint, and even firing silver stain, is nowhere near as complicated or unpredictable as firing ceramic glazes. Each day I count my blessings I’m a glass painter (not a potter).

And if you’re looking to buy your own kiln, take your time and research the subject first: yes, that does mean reading through a lot of technical material. Here, things will get unavoidably scientific. Enjoy the ride!
