The Thermal Shock Resistance, or TSR, of an item relates to its resistance to fracture when suddenly quenched from a high temperature to a lower one. Justify the expression for the TSR:
Where k is the coefficient of thermal conductivity. Look up reasonable values for these parameters, and compare the TSR of quartz, soda-lime and borosilicate (Pyrex) glass. Explain the differences between these values on an atomistic basis.
