Abstract
Abstract A method and apparatus for determining the temperature at which a transformation occurs in a castable material such as a latex emulsion, a plastisol, etc. The apparatus includes a thermally conductive test block including an elongated test surface thereon having a temperature gradient thereacross. Heat is applied to the test block at a plurality of spaced points therealong, and heat is removed from a plurality of points disposed between the heat input points. Means are provided to selectively control the amount of heat supplied to and the amount of heat removed from each of the various zones along the length of the test block. Temperature measuring means such as thermocouples are placed in the test block along the length of the test surface to ascertain the temperature therealong where a physical transformation occurs. The physical transformation may or may not be visible to the operator.
