Britteniss is chalk glass or iron
Answers
Iron
A material is brittle if, when subjected to stress, it breaks with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a snapping sound. Brittle materials include most ceramics and glasses (which do not deform plastically) and some polymers, such as PMMA and polystyrene. Many steels become brittle at low temperatures (see ductile-brittle transition temperature), depending on their composition and processing.

Answer:
your's brittle spelling is wrong.
Brittle materials break without significant plastic deformation under tensile stress. Also called sudden failure.
