Ostwald ripening is actually a general term for certain kind of crystal forming. This phenomena can occur in solutions and is definitely not limited to solid rock.

Idea is that first small crystals appear because this is kinetically favorable. However growing large crystals are thermodynamically more favorable and thus small crystals will slowly disappear while they are feeding large growing crystals.

Someone with beter knowledge of the phenomena should edit the article though!

Better explanation: Ostwald Ripening

[edit] Ice cream

This is also what happens when ice cream warms and then refreezes: the number of ice crystals decreases and their size increases. Sendhil 20:50, 20 July 2006 (UTC)

[edit] Copyedit & such

I've tried to make the article more readable, and reduce copy-edit problems. I also took out the discussion of kinetics, as Ostwald ripening is a thermodynamic process, and while kinetics does play a large role in crystallization, it was getting the discussion somewhat confused.

]]]]== Question for a Geologist == Regarding this quote from the article:

In geology, it is the textural coarsening, aging or growth of phenocrysts and crystals in solid rock which is below the solidus temperature. It is often ascribed as a process in the formation of orthoclase megacrysts, as an alternative to the physical processes governing crystal growth from nucleation and growth rate thermochemical limitations.

What is meant by thermochemical here? Is this meant to be distinct from chemical thermodynamics? Any help would be appreciated. --Bfigura (talk) 05:13, 15 November 2007 (UTC)
