Most incandescent light bulbs contain a trace of krypton gas which I assume is there to help lengthen filament life (possibly by reducing filament evaporation rate at operating temperature?). I've deliberately exploded incandescent light bulbs in microwave ovens but it has puzzled me why the bulb shatters (often with little or no evidence of melting first). Thermal runaway is more typical of electrically conductive liquids such as salty water.' Some ceramics can also be melted, and may even become clear upon cooling. Additionally, microwaves can melt certain types of rocks, producing small quantities of synthetic lava. An example is glass, which can exhibit thermal runaway in a microwave to the point of melting. ' Microwave heating can cause localized thermal runaways in some materials with low thermal conductivity which also have dielectric constants that increase with temperature. I'm guessing the initial heating is due to heat transfer from the contents of the glass container, for example, after which thermal runaway takes over once the glass temperature reaches some critical threshold at which changes in the dielectric constant favor this effect. I've never had problems using glass myself. Fortunately, most common kinds of glass seem to absorb little energy at the wavelengths typically found. Ran across this bit (below) about the use of glass in microwave ovens.
