  The precipitation of a glass forming solute from solution is modelled using a
lattice model previously introduced to study dissolution kinetics of amorphous
materials. The model includes the enhancement of kinetics at the surface of a
glass in contact with a plasticizing solvent. We demonstrate that precipitation
can produce a glass substantially more stable than that produced by very long
time annealing of the bulk glass former. The energy of these ultra-stable
amorphous precipitates is found to be dominated by residual solvent rather than
high energy glass configurations.
