Solids having constituent particles with irregular with shapes and short range order are called amorphous solids. Amorphous solids are isotropic in nature and melt over a range of temperature. Thus, amorphous solids are also referred as pseudo solids or super cooled liquids. They do not do not have definite heat of fusion. These solids give irregular surfaces, cut with sharp tool. Glass, rubber, etc. are some examples of amorphous solid.
