Thermal shock is not a big deal in glass painting. They have used gas
fired flash kiln for decades, and you can fire a painted piece of
glass to 1250 and back in 30 minutes. As for the question. Yes, a top
fired kiln is fine, it gives even heating over the entire surface of
the glass with no hot or cool spots to worry about. You can fire on
the floor of the kiln with no shelve. The only time a shelve would be
important is when firing silver stain down. You don't want to
contaminate the kiln floor. As for size, once you own a kiln you will
find other uses for it. I would suggest to get the biggest one you can
afford. Some day you'll need it.

1250 and back in 30 minutes? What size is this glass?

Click on kilns, Speeed burn III
I have heard but never seen a gas fired flash kiln, there used to be one in
the old Detroit Stained Glass Works, I hear, but I don't know what ever
happened to it,or how to operate one.
I would like to know more about them, for instance, do they have a fan of
internal air movement, so the act like an annealing tunnel lehr? How do
they work? Especially that fast.
I don't how or why it worked. It just did.
Sounds like the one from Detroit, a guy had it for sale in his driveway,
wonder if he still has it??
The operation was that simple? open bottom? gas jets shoot across the top
of the glass about 3-4 in above the glass surface? I remember looking in
one end and thinking "How the heck?" but seems he had it pretty high for
what it looked like in my ignorance. Think I will make a phone call
tomorrow.
Kilns are expensive, but I take the opposite approach from most
people... rather than say "get the largest one you can afford", I say
"get the smallest one that will do the job". If you need a bigger kiln
later, you can buy one later, and then you'll have a very useful,
energy-efficient small kiln as well as a big mother for big projects.
'Course right now I wish I had a *really* small kiln for really small
projects.

A&S Glass Specialties in Huntington Beach CA. also list themselves as
distributors of the Hoaf Speedburn. Their rep was friendly and sent me some
lit. But their website doesn't work, and they return their phone messages
cell phone, so it makes me wonder whether their post-sale customer service
will hold-up.
I'm just not able to come up with 4K$ for a 16x16 Painting kiln. I saw them
in action in the two painting courses I took last year. They're the best
tool for the job. 45 min turnaround for painting, for a few pennies of
propane. You can kep it in your garage, and don't need 220V electric. On the
other hand I could buy a Skutt clamshell electric for 2K and turn painting
aournd in two hours (my guess ), but I'd need to wire it and keep it in one
place. I'm also waiting for Jen Ken to complete an electric painting and
glass tile kiln they've been developing. But they've been developing it for
years. Its alright. I don't have the money right now anyway. My painting
turns around in about five hours if I push it. (octagonal side-fired
electric)
