Hello,
I have a medium/large gas kiln with 2 burners at the back/bottom. It
resembles a large steel safe with fibre-lined walls. The floor is kiln
bricks. The door has a large bunghole and bung and I don=92t use cones as I=
rely on my pyrometer.
Lately I have been making smaller items and want to attempt to temporarily
reduce the inside diameter of my kiln to make quicker more economical
firings.
I was thinking the best way to do this (as I have spare kiln bricks lying
around) would be to =91build in=92 the walls by stacking bricks from the wal=
ls
in. Perhaps capping this off with a shelf and continuing the bricks to
the ceiling. Although maybe a tall skinny space would suit better as my
pyrometer comes in through the top of the kiln.
Would this work and which design (up/down/cross draft etc) would you
suggest. I=92m leaning towards down draft?
I thank you in advance for any advice which you may have, I can also take
pictures of the procedure, firing array and the completed firing for your
site or just for your own curiosity.
Hope to hear from you soon with your thoughts and suggestions.
Kind Regards,
Mandy Brown

Mandy try to contact Lawrence Ewing =
http://www.matrix2000.co.nz/Contact.htm
the author of the Matrix Glaze software from the addres on his site. A
couple years ago when he went back to more full time studio I believe he
built a kiln within a kiln=20
I think he used fiberboard , so he could run glaze test in a reduction =
kiln
before commiting new glazes to a whole load. I think he had written it =
up
for the New Zealnd potters org. and had a picture

i did this one time was fooling with saggers in my large electric kiln. i
raised the floor with a kiln shelf on stilts and used keowool to take up
the space between the walls and shelf then just fired the top elements of
the kiln.

Hi Mandy,
If you put bricks in your Kiln remember these have to be heated, using
energy and thus defeating
the purpose of the exercise.

I was thinking the best way to do this (as I have spare kiln bricks lying
around) would be to 'build in' the walls by stacking bricks from the walls
in. Perhaps capping this off with a shelf and continuing the bricks to
