Abstract
A method and apparatus for monitoring the progress of the solidification of a solidifying material involves using a transmitter to transmit a relatively low frequency compression wave to the solidifying material. A receiver is provided for detecting the resonant compression wave vibrations induced in the solidifying material, and the detected wave vibrations are analyzed to obtain an indication of the progress of solidification.
