[QUOTE="araucaria, post: 29126, member: 2189"] I don't do emax but investment principles are all pretty similar across the range I'd have thought. First for me is to check the furnace temperature (calibration?) and rate of climb. Moisture content - waiting before put in furnace. Position in furnace. Then back to powder and liquid condition, how is it kept and is the liquid affected by temperature - time of day in lab for mixing, is there an environmental change? Is the vac-mix unit pulling vacuum properly? blockage? Contamination?? Good luck with the quest - problem solving is a very valuable aspect of our profession, and the time we can potentially save is worth a lot of money to us. [/QUOTE]
