[Rockhounds] Mother's pressure cooker... Mineralogical use?

[Axel Emmermann]

Good morning esteemed list-dwellers,

My wife and I were cleaning up (finally) our garage when we stumbled upon
several arachnoid garage-dwellers and a pressure cooker that once belonged
to her late mother.
The flattened remains of the aforementioned arachnoid garage-dwellers are of
no interest whatsoever here so we shall not dwell upon those and exclude
them from this discussion forthwith. As my lovely wife went forth to place
the pressure cooker near or upon the pile of garage-garbage*  that had we
had already collected I had an epiphany and, with a formidable leap of
almost Olympic allure, I tackled the poor woman.**

On the downside: I shall not have to concern myself with planning elaborate
nocturnal escapades of matrimonial nature for at least a week. Tackling your
wife on a cement garage floor in not considered as particularly romantic or
good foreplay.
On the upside: after being beaten senseless with it I now have in my
possession a working pressure cooker. That is to say: it will be complete as
soon as I pass the weight, you know , the whistling thingy that hisses and
dances on the lid. (Boy, was she mad...!). 

What I actually wanted to know is this: can a kitchen variety pressure
cooker be put to work for any mineralogical purpose?
I mean things like inserting activator ions in minerals, recrystallizing
stuff like gypsum
 etc

It'll reach about 120 - 129 ° C, which corresponds with a pressure of
roughly 30-38 psi (2.1 - 2.6 bar).

* do not attempt to read this if you are even remotely dyslexic
** Pardon me the archaic language but I hate garage cleaning, it makes me
long for the time before the invention of the automobile and thus, by proxy,
the garage.

Cheers
Axel
