Volcanic ash is a mixture of rock, mineral, and glass particles expelled by a volcano during eruption. The glass particles are a result of the speed at which the magma cools down from its molten state. Volcanic ash is less than two millimeters in diameter, but there are also huge particles called "lapilli."

Volcanic Ash encounter can result in engine damage and malfunction: Engine Malfunction. The principal risk to continued safe flight, arising from flight through high concentrations of volcanic ash, is the melting within the engine of ash particles, which are predominantly composed of silicates with a melting point of 1100°C. When volcanoes erupt explosively, vast amounts of lava, rock, ash, and gases are thrown into the atmosphere. The solid parts, called tephra, settle back to earth and cool into rocks with pyroclastic textures. Pyro, meaning fire, refers to the igneous source of the tephra and clastic refers to the rock fragments.
