A hot deformation tester to determine the ability for a sand and binder combination to withstand high ambient temperature without deforming excessively. An insulated chamber receives an elongated core sample on two spaced supports, and applies a weight to the center of the sample. The sample is subjected to ambient temperature of about 600 DEG F. A deflection probe in engagement with the bottom of the sample measures the deformation of the sample.
