In order to know the influence of laboratory temperature on the properties of the quick-heating investments, the setting expansion, heat expansion roughness of mold and casting accuracy were measured at 16℃,23℃, and 30℃ under 60% humidity. Results were as follows:<br/> 1. With a rise in room temeperature, the setting expansion was increased.<br/> 2. With a rise in room temeperature, the heat expansion was decreased.<br/> 3. With a rise in room temeperature, the roughness of casting was increased.<br/> 4. With a rise in room temeperature, the surface of mold for dimple was increased.<br/> 5. With a rise in room temeperature, the casting shrinkage was decreased.<br/>
