No idea about English, in Polish it is called aging - that is, smaller crystals of precipitate dissolve and larger ones grow, making precipitate easier to filtrate.

Digesting is a completely different process.

Yes! Aging is just the term I need! How is digestion different from aging?

IT's only a linguistic/semantics difference---sorta like we often say in the lab either "fill to the mark with di water" or "QS with di water".

When I think of digestion, I think of dissolution or dissolving something with a chemical connotation (i.e. I don't see dissolving sugar into hot water as being a digestion, but I think of dissolving silver into nitric acid as being a digestion).

Aging is different than digestion and is exactly as Borek described.
