Hey Guys,
This post from Dec. 1st has shown up on my news reader as new today even
though I have already read it and deleted it before. I have been noticing
this problem lately on my groups. Has anyone else had this problem? Are
the servers burping 8-}

Hi All
I've been using a little Paragon SC2 front-loading kiln for the last 6
weeks or so - mostly making small fused pendant pieces, dichro,
earrings - that sort of thing.

I'd noticed that not all of the pieces in each firing were fusing
fully - and recently seem to have discovered that the 'bad' pieces are
located at the front and right side of the kiln.

Things came to a head the other day when I tried fusing a large piece
of glass (well - 5" diameter - which is large in relation to the size
of the kiln). The left side of the piece fused well - but the right
side was less well fused.

I wondered if there was a problem with the kiln door not closing
tightly, and tried, on the last couple of firings, to introduce a
'gasket' of fiber-paper around the door - not sure yet if it makes any
great difference. Paragon say that the door gap is to allow for
expansion.... and suggest that I 'bring the glass up slower as to heat
soak the ware to it maximum'

I guess the question I'm asking is - 'Is it normal that you get hot /
cold spots in a small kiln like this ?'
If it's normal, should I simply increase the time at the top
temperature so that the 'cold' spots get hot enough to fully fuse -
it's a pain and time-consuming at the moment to have to re-fire pieces
that didn't work the first time around..

Any sugestions welcomed
Thanks
Adrian



Nope, mine still says it was posted on 12/1/05 must be your service or
your reader, gathers it after you delete, why not let the reader delete it
on its own when it gets too full?

Thanks for the link back to your site - I see the price now....
..... but I'm still not convinced that purchasing a copy of the
software would help in my circumstances. Thanks anyway.

I'm pleased to report that I'm getting much better results with a
slower first ramp, plus a 30 minute soak at the end of the first
ramp-up before a 'slower' ramp up to full fuse at 815c.
Perfect fusing everywhere on the shelf - great !

Seems that this small kiln wants a bit of time at the various temperat
temperatures for the glass temperature to 'catch up' with the air
temperature (as measured by the thermocouple).

Thanks all for their help and assistance
Adrian

Got an Idea for you Dennis, why don't you team up with AOL ??

They are trying to make the world a "dumber" place by taking all thinking
out of the hands of computer users and you can do the same thing for the
glass fuser with this program that doesn't let a person think.

I mean really, do you want people that can't think operating really HOT
ovens? Much better they don't know how to operate their kiln but can follow
instructions on a program...

I have a better idea - treat luddites as being inconsequential and
irrelevant.

Have you considered adding a kiln controller to eliminate having to
babysit your pyrometer?

So it's true. Luddites prefer to travel in herds.

So, thank you, now I know more about English labor history, and it's crowds
and mobs, not herds, but I bet in the day you would have been a mill owner,
and right happy with it.

Your facts are a bit messed up though, while I don't go for the machine made
product, I also don't believe stained glass windows and lamps are meant for
the masses. They are something that should be reserved for those that can
afford them, and the hand made price they should command.

Keep adapting Dennis, at least, that's what you call it, I call selling out,
making a buck from the hard work of others, you would have made an perfect
example of a mill owner, and were I a luddite, I'd have burnt yours down
first...

With him inside?

I wish no ill health on anyone, would bother him more to watch it go...

Is it modernization you fellas are opposed to - or just entrepreneurial
capitalism?

Adapt or die. If you can't compete, clear the field to make room for
those that can.

Ok, let's get this adapt or die BS off the map, DEFINE "adapt"? Define
COMPETE, and if I'm in your way on the playing field, how come you have so
much involved with selling supplies to people that should be BUYING at the
price YOU are BUYING at? Not the price you WANT to sell it for.

If by ADAPT you mean build it for less and sell it for less, you must be
nuts.
I should cut my labor so Joe the butcher can afford a pretty lamp? What do
I give a damn if he can afford a pretty lamp? I don't and I don't compete
with the Chinese labor market for anything I do. So define ADAPT.
I do not intend on changing a damn thing, and I will die when my tired old
body slides into the grave sideways, screaming, "What a ride!" Not because
some goof north of the border wants to spring on the scene suddenly with
"Adapt or die" as some catchy slogan to scare the wits out his local talent.

Compete? With who? You? Surely you jest? You would not dare to try and
compete in the same market.

Do you have any idea who my clientele is? Other glass studios, small
churches and antique dealers, antique dealers that sell things like original
Tiffany Studios Items, lamps, windows, and desk set pieces. Handel, Unique,
Duffner Lamps. name studio windows, serious collectors

My clientele is very demanding, from the beveling. to the bending, painting,
staining, restoration and repair.
Not one little boat in the bunch, and the last time I sold glass, a guy
drove 6 hours to see if maybe I had some old stuff that would work for a job
he was restoring in his studio, ( I did and it worked for him, cost him more
in time and gas than the glass did, but he had to chose from several pieces
as to what would work, and it was made over 90 years ago. Got any of
that? )

I am opposed to arrogant pompous asses, jumping into a trade and "mucking it
up" to make a name for themselves where none is warranted.
If your work is good enough it will speak for you, and those who need to
know you, will.
