It would be interesting to try these out with a capacitance meter at 
various temperatures. See how capacitance and loss changes over time. 
The memory effect would also be fun to test if it changes. Should be 
enlightening. Another thing would be to see how it varies with applied 
voltage.

Sounds like a fun project. Have fun!

Cheers,
Magnus
