Dear Gail;

I am not familiar with the Olsen design, but if there is 'something
missing' you could cast a connection with a good castable
refractory....... one that would have a service limit of 2200 degrees
fahrenheit or more. These are eassy to use if you follow directions
carefully.

Cheers, Hank in Eugene

Great idea. I even happen to have just the right amount of kwool sitting=

unused in a box. I intended to use it to built a portable raku kiln, but=
I
never got beyond the intention.
I'm a big fan of very slow cooling, so any insulation I put on the top wi=
ll be
a big help.
Thanks for your help,
Gail

Hi Gail,

I placed a blanket of kwool on the top of my Olsen kiln, completely cover=
ing
all but the opening. I have no rack, the damper shelf slides on two kiln=

shelves that are placed on either side of the opening, I use glaze tongs =
to
open and close it.

I think in a cold climate the kwool would help a lot to prevent premature=

cooling. Even in California it works well.

Best, Rikki

I bought an Olsen downdraft kiln which had been sitting unused for several
years and I am trying to bring it back to life. All has been going well, we
built a nice shed for it, we figured out the plumbing for the gas and will
have a propane tank on site within a couple of weeks, but the damper on the
top has me stumped. There is a steel rack built a couple of inches above
the
kiln into which a kiln shelve will fit and move back and forth, but what
happens between the top of the kiln and the moving kiln shelf? There seems
to
be something missing.
No one in the Fairbanks area owns a similar kiln, so just going to look at a
working example and copying it is turning out to be hard. Are there any
potters elsewhere in Alaska who fire an Olsen downdraft? Or can someone
send
