I am curious how you would change the protocol described in the opening post for an oxygen-free jar method. Would you still do the compacting in aluminum foil?

Also, what about processing times and temperatures - I imagine adding a jar will significantly reduce heat transmission, and slow things down quite a bit. We're also adding quite a bit of ethanol vapor, and also water vapor as a product of burning ethanol. Since you mentioned water to be one of the potential reagents we don't want a lot of, I'm just wondering if this is something we need to be worried about.
