Series solution calculations of cooling rates are applied to a variety of samples with different thermal properties, including an analog of an Apollo 15 green glass and a hypothetical silicate melt. Cooling rates for the well-studied green glass and a generalized silicate melt (density=2.5 g/cm3, heat capacity=0.3 cal/g¿ C, and thermal conductivity=0.005 cal/cm⋅s⋅¿C) are tabulated for different sample sizes (0.01-1000-cm half thicknesses), equilibration temperatures (2000¿, 1400¿, and 620¿C), and quench media (vacuum, air, liquid nitrogen, water, silicone oil, and liquid tin). Results suggest that cooling rates are heavily dependent on sample size and quench medium and are less dependent on values of physical properties. Thus cooling histories for glasses from planetary surfaces can be estimated on the basis of size distributions alone. In addition, the variation of cooling rate with sample size and quench medium can be used to control quench rate.
