just to clarify - the ceramic tube is open on both sides, correct? I can't see how it would work otherwise but want to double check. Have you just chopped the end of a standard thermocouple sheath?

Hi Joe,

Thanks for the very helpful information and images. I'm planning on firing a small Bailey gas kiln (cone 10) soon and will be reduction cooling it, so I am primarily interested in keeping track of the atmosphere as the kiln cools. One burner will be on low and the other other burner port will be bricked up. The damper will be all the way in. I'm aiming to keep it in reduction until about 1600F.


Two quick questions:


1. You mentioned removing the sensor as soon as temp is reached. Do you forsee any problems leaving it in as the kiln cools - the whole reason that I'm using it is to keep the kiln in reduction down to 1600. Would it be too much thermal shock to the unit to insert it at the end of the firing?


2. I'm going to be renting a kiln at a local craft school and will not be able to drill a whole in the back wall. Do you see any problem with inserting it through one of the spies, as long as i make sure that it is airtight? I will have the other one plugged up completely once the cones are down.


thanks again!
