[time-nuts] Improving the stability of crystal oscillators

Something I've been thinking about is attaching a large thermal mass of 
aluminum to the crystal and it's oscillator then surrounding that with 
insulation.  Then surround that with a thin copper layer.  Temperature sensors 
on the copper and aluminum.  If the thermal time constant could be made very 
close to 24 hours, or integer multiples of that, it might be possible to 
predict the inner temperature allowing compensation.

Has this already been done?

Have Fun,
