hi randy,

230F = 110C, which is fairly chilly.  i don't have my data sheets 
handy, but glass/metal seals have numbers like 175C and ceramic/metal 
about 250C.  that's *at the seal* ...  you didn't say where you're 
measuring.

you'll probably get a reply from somebody who has the data sheet at 
hand, instead of relying on my memory.
