Hank in Eugene here;
Not wanting to offend a Senior Potter; but the OxyProbe(or KilnFinger if you prefer) works really great if you stuff the ½" tube into a ½" alumina tube just ¾" longer than the end of the probe. This action prevents the embrittlement of the exterior platinum wire that can be affected by reduction, getting stiff and brittle over a few dozen fires and finally breaking.
If that has happened to your Probe, just take it to a jeweler of your choice and have him/her weld a bridging piece of Platinum wire in place of the removed brittle part_____ usually just a couple of inches @ $8/inch. I have had those repairs made to several OxyProbes, and mine is going on 200+ firings with no problems.
Jeez Mel, hope you are feeling better,
Yer pal Hank
