A composition for use in a reversible thermometer comprising a thermally responsive material capable of being supercooled for several minutes, and of changing state from solid to liquid at a predetermined temperature, means for visually observing the change in state, and a matrix forming material in which the thermally responsive material is dispersed, the matrix material comprising an amorphous organic compound, and being insoluble in the thermally responsive material. A suitable matrix material is polyisobutylene, and a suitable thermally responsive material is a solid solution of ortho-chloronitrobenzene and ortho-bromonitrobenzene. |
