Scratch resistance of sodium borosilicate glasses (20Na20-80 (1-X)Si02-40B203, X = 0,0,2,0,4,0,6,0,8, 1) was investigated by using a Knoop indenter. In addition, Vickers hardness, Young's modulus, and fracture toughness were measured and their compositional variations were compared. It was found that the scratch hardness test was a simple and useful method for evaluating the mechanical failure in glass.
