Volcanic ash normally contains glassy materials, such as silicates, whose melting points are 600 degrees celsius to 800 degrees celsius. Since internal temperature of in-flight jet engine exceed 1000 degrees celsius, glassy particles in volcanic ash inhaled by the engines instantly melt. In the course of exhaust, the glassy materials are rapidly cooled down in the turbine chamber, stick on the turbine vanes, and disturb the flow of high-pressure combustion gases. This disorder of the flow may stop the entire engine in serious cases.

You'll not see me on any plane for a while.
They would be wise to keep tabs on every aircraft that flies in this area...
