Abstract The effect of the time between mixing and heating on the expansion of four phosphate bonded investments was investigated. Setting and thermal expansion of the same specimen was measured in a dilatometer. Unexpectedly large differences in setting expansion occurred between the investments. The combined setting and thermal expansion of one investment was affected by the time between mixing and heating.
