What is the difference between digestion and aging of a precipitate?

  1. Is digestion related to heating and aging related to allowing the precipitate to sit?

  3. Digestion is related to the reduction in number of the little solid particles of precipitate and the growth of the bigger and purer ones, so that, at the end of the process, all the precipitate is in the form of big, heavy and pure solid particles/crystals and you can easily and quantitatively separate it from the solution. *In general* this is achieved by heating the solution for long time (maybe even adding chemicals which favour the process).

    Didn't know it is called digestion. For sure I have heard the procedure called "aging". Perhaps digestion and aging is the same then (in this context).
