Maintaining a temperature of 70 degrees in a metal powder

[trini]

I am making a bonded magnet and have the need to maintain a temperature of around 70 C in a magnetic powder compressed in a stainless steel mold for a period of about 2 hours, before cooling rapidly to room temperature. i was thinking about using some sort of infra red heating, but would like to see if you all could make some simpler suggestions.

How about your oven? Or maybe even a toaster-oven if your rig is small enough.

i can't fit it into an oven, it has to be out in the open.

Just boil something with that boiling point or close to it. Somehow alcohol comes to mind but it's 78'C.

An electric oven can be used to heat another chamber, a bigger one. use a thermocouple to get the temp right.

I don't really know anything about this stuff, but can you use RF radiation to heat the mould directly?

ok i did some more reading and now find that if i can heat it to about 250C using SHF Infrared, i would not have to then hold that tempeature at all. what kind of lamp can i buy to emit IR of frequency between 3-30 GHz?
