But saying this I have found the Microstar to be the most accurate once you get your ratios dialed in. The chart that is sent with the investment is VERY close. I also check all my castings under forty power magnification and I am not seeing a problem. One thing I also want to mention is a lot of manufactors are having trouble with getting a consistent quality of base material that goes into investment. This is a by product of the plaster board industry, sheet rock. The reason I mention this is I have been running into problems with other investment breaking or blowing up in the burn out furnace. Man what a waste this can be!! I have used several investments and the Microstar is the only one I have not had this problem with. Good Luck, Byron

Byron what does HS stand for? High Strength, High Speed?
I have been thinking about switching from CB 30. I have been using it forever but it is not consistant anymore. Mabey its their liquid I dont know. I never have had a blowout but the fits change at times. I always had adjustments with season changes from summer to winter but sometimes Ill have 3 or 4+ cc
fit changes regardless of weather. I had a few boxes where they put some kind of musk perfume in the powder.
Also since Ive bought the emax system, their investment is so nice and smooth and bubble free that my fitting time is 0 on pressed crns.
I figure that there is a C&B investment equally as good as emax investment.
Ive always heard very good things about Microstar. Mabey Ill order a box.
