The insullation that was probably built into the kiln stands on my L&L
kilns has fallen out and I'm wondering what to do. Before I heave those
suckers apart, do any of you have suggestions for good things to put under
the kilns. Both kilns tend to be cold on the botton layer. My husband has
some sheet asbestos and thought that might be a good idea to put under them
before returning to the rack. Some folks fire their electric kilns right
on the concrete floor-what is the story about that? I fire several times a
week when I am on a roll-bisque and ^6 both. I would love to have the
bottoms better insulated. There are not elements in the bottoms or the
tops. Thanks for any insights.

Hi Barb,
Are you sure the insulation came from the kiln stand? My guess would be
that the bottom of your kiln has rusted out. This is quite typical with
kilns that have extra insulation (not always a good thing). The insulation
can collect moisture, which gradually eats away at the case (probably thin
sheet metal). An industrial kiln of this type would most certainly have a
stainless steel case to avoid this.
If this is so, you will need to replace the insulation & install a new
bottom pan. Check our service directory
http://www.euclids.com/servicedir.htm for a repair person near you.
Regarding the elements, the design on some of those older kilns can be
improved to give a more even firing.
Let me know how else i can help,

Barb, I was having difficulty getting to temp. on the lower ring of my L&L
and decided to purchase a second kiln floor ( since these come in sections
anyway) and it has helped considerably. I have an envirovent on the bottom
and was told by the kiln sellers that should even it out NOT!!! The
second layer of insulation from the additional floor did the trick and it
now gets better temp than the top. May get a second top too. I happen to be
trying to push the limits of the kiln since I had to go to a 2 tier kiln
from a three after a back injury . The loading is much easier ( I have the
kiln elevated on cinder blocks ) but I was unaware that by going to a 2
level from a three the max cone temp went from cone 10 to cone 5. Found
with the extra top and bottom insulation and some extra time I can push it
to cone 5 1/2 to 6 And have gotten some nice results that I didn't get with
the faster 3 tier firing.

barb , i have fired my bisque kilns on a cement floor for over twenty years
with out any problems . I recomend that you put down a layer or two of soft
brick and place kiln directly on top of them

Dear Barb:
We did indeed used to use a layer of mineral wool insulation on our kiln
stands. Those old stands (we are talking probably 20 years old) were made
out of painted carbon steel and should be replaced with a newer aluminized
steel stand. We are working on a design that will have a full sheet metal
plate under the kiln bottom. YOu could put a layer of calcium silicate on
this which withstands 1200 Deg F and is very solid. Another idea is to put
an old top or bottom under your good bottom and thereby have 5" of brick
insulation.
