It is possible for the tuning fork element of a 32.768 kHz quartz
crystal to be used in an oscillator circuit if the element has been
exposed from its case and immersed in water ? Or is its Q factor now
too low ? The element exposed to air will produce slightly higher
frequencies than 32.768 kHz when used in a CMOS 4069 inverter gate
circuit using a 10 M ohm resistor (gate out-to-input) and 10 pF from
gate inverting input to ground.
