Answer:

If the temperature is sufficiently above the decomposition temperature, the mass of the mass will reach a steady level.  When this occurs, the decomposition is complete.  

Explanation:

If you have money and a mass spectrometer, you might consider monitoring the gas space above the zinc carbonate sample for CO2.  Once the sample stops emitting CO2, above the decomposition temperature, you may conclude the reaction has gone to completion.
