crystallization
Let an agent explain crystallisation, relay mechanisms, methods and applications from chemistry, materials and geology sources, describe the named forms and flag the misfiled alias, and distinguish crystallisation from precipitation of amorphous solids, solidification of glasses, evaporation alone and hydrothermal liquefaction.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain crystallisation, relay mechanisms, methods and applications from chemistry, materials and geology sources, describe the named forms and flag the misfiled alias, and distinguish crystallisation from precipitation of amorphous solids, solidification of glasses, evaporation alone and hydrothermal liquefaction.
The process by which atoms or molecules arrange into an ordered crystal structure, from a solution, melt or vapour, through nucleation and crystal growth, used as a purification method in chemistry through recrystallisation, as a separation method in fractional crystallisation of mixtures and magmas, in microcrystallisation for small samples, in hydrothermal synthesis of crystals from hot aqueous solutions under pressure, and in the partial crystallisation of polymers; the registry alias hydrothermal liquefaction names a process converting wet biomass into bio-crude oil, which is not crystallisation and appears misfiled. Crystallisation also occurs naturally in minerals, snowflakes and kidney stones.
What it is for: Forming, purifying and separating crystalline solids.
It can be explain nucleation and growth; relay laboratory and industrial methods; describe named forms; flag misfiled aliases.

How it is recognised
Formation of ordered crystals
Recrystallisation, hydrothermal synthesis, microcrystallisation, fractional crystallisation, crystallisation of polymers, hydrothermal liquefaction
Amorphous precipitation lacks order; glass solidifies without crystals; evaporation removes solvent; hydrothermal liquefaction makes bio-crude
