I am making a fiber module door for my gas kiln (firing to cone 9) and am
looking for a clay recipe from which to throw the spy hole cylinders. If
anyone has a good recipe I would really appreciate it.
Or if any one knows a place to buy manufactured super high duty cylinders
for this purpose , that would be great too! - approximately 4"- 4 1/2"
wide x 6"long.

Hi, I made my own, just get some stoneware clay and fire to ^10 without
any glaze.

why not use some large round kiln posts...they make great spy holes.

If you want to make your own, use EPK or any other pure kaolin and blend by
volume about 50% fine sawdust. Add enough water and mix to make a ramming
mix. Place the mixture in a tin can (cut both ends out first) of the size
you want for the outside of the peep. Find a tapered object like the snout
of a very large plastic funnel, coat it with oil or WD-40 and place it
inside the can and pack the moist clay-sawdust in tightly until the can is
full. Carefully remove the funnel.
Oil the inside of the funnel snout and pack it full of the same mixture.
Mixture can be left inside the can and snout since it will shrink as it
dries.
Once dry, fire in the hottest part of the kiln to complete the process and
then coat both the plug and the plug acceptor body with Sairset mortar and
let dry. The plug acceptor can be installed into Kaowool using Sairset and
this kind of peep lasts a long time and costs next to nothing to make.
