  A bond-disordered two-dimensional Ising model is used to simulate Kauzmann's
mechanism of vitrification in liquids, by a Glauber Monte Carlo simulation. The
rearrangement of configurations is achieved by allowing impurity bonds to hop
to nearest neighbors at the same rate as the spins flip. For slow cooling, the
theoretical minimum energy configuration is approached, characterized by an
amorphous distribution of locally optimally arranged impurity bonds. Rapid
cooling to low temperatures regularly finds bond configurations of higher
energy, which are both a priori rare and severely restrictive to spin movement,
providing a simple realization of kinetic vitrification. A supercooled liquid
regime is also found, and characterized by a change in sign of the field
derivative of the spin-glass susceptibility at a finite temperature.
