Terms commonly used to describe the tenacity of a mineral are brittle, sectile, malleable, flexible, elastic, ductile, and tough. Minerals can be described as brittle, ductile, malleable, sectile, flexible, or elastic. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool.
