Configuron is an elementary configurational excitation in an amorphous material which involves breaking of a chemical bond and associated strain-releasing local adjustment of centres of atomic vibration.[1]

The higher the temperature of an amorphous material the higher the configuron concentration. Formation of configuron percolating clusters at glass transition temperature explains the glass transition phenomenon. Clustering of configurons above glass transition temperature facilitates the viscous flow in melts (see viscosity).
