an autoclave would be preferred.. failing that, a pressure cooker?

I may be mistaken, so I hope other more knowledgeable people will chime in and either confirm or dispute. I think you need to hit well past 500f to have a negative effect on the temper.

The temper temperature curves are easy to research.

In the kitchen oven at cooking temperatures it is time at temperature.

A pressure cooker is a good thing but not for some scales. Place the
object on a rack so it is in the live steam.... 15psi is the normal
pressure cooker pressure limit. 15psi maps to about 250 F.

This temperature+time interaction is important to the DE blade folk
because the PTFE coating requires enough heat to change the temper
too long and the blade stinks, not long enough the PTFE does not stick.
The now expired patent is easy to find with a bit of looking. PTFE does
help too....

I was reading something that a guy linked to over at B&B and the study indicated that, while rubbing alcohol is an excellent skin disinfectant, it doesn't do nearly as well as a surface disinfectant. I have heard that Lysol is very effective...and something that many of us already have in the house or can get at pretty much any local store.
