Sclerometer
The sclerometer (aka Turner-sclerometer; from the Ancient Greek σκλερος meaning "hard") is an instrument used by mineralogists to measure the scratch hardness of materials. It was invented by Prof. Thomas Turner in 1896.
The Turner-sclerometer test consists in measuring microscopically the width of a scratch made by a diamond under a fixed load, and drawn across the face of the specimen under fixed conditions.
