I plan to do screen printing on glass and wondering if all I need is a
top heating kiln. I was looking at a Evenheat GT 22 on ebay with top
and no controller for $850.00 and it had no use on it. Would this be a good
direction to go in...11X17 would probably be the largest size I would fire.
I the floor area of that kiln that big? Got to allow a little room around
the shelf for air flow under the shelf too, avoid thermal shock. Why do you
have to have a top fire for glass painting? I know of several people that
fire paint in old ceramic kilns and do just fine, but the floor area may be
a problem there too, but they sure are cheaper and easier to find.
If all you want to do is paint on glass or fuse flat glass without
slumping then a topfired one is more efficient than a ceramic one.
However most people working with glass use their kiln for more than
one 'discipline' and accept the fact they may be heating up more cubic
area for longer to have the advantage of more height when slumping,
potmelting, casting etc.
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.
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.
The old one that I saw was at Rambush.It was about 2'x4'. Curved top,
sides open about 6" from shelve to side of top. It had about 8 gas
jets of either side of the shelve. Shelve was on a track and would
slide out the end. Turn on the gas, watch the paint till it got
glossy, Turn off kiln. ALL DONE.
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
In article ,
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
Thanks for everyones replys! After posting I found a shop
that will be having a class on screen printing on glass and
signed up for it. Hopefully after taking the class I can put
all the good info to work for me.
I have an email into Fusion HQ for more info about their next generation
Hoaf. Hoaf apparently has an replacement for the Speedburn II termed by
as the 'Flexburn II'. Not sure what Gill is calling the
Speedburn III. The gloss literature I have on the Speedburns list Speedburn
II and 1V and larger models, but I don't see a Speedburn III.
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
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
