pushing the limits of thickness!

ok so i wanted to see how far i could push the thickness of my fluids. this was following suggestions from my team about getting it more smokey. i didnt just want to immediatly start fine tuning somthing before trying to understand it so i went ahead and did this test to see how solid looking i could get my render out. this in my mind looks like cement!

obviously not what we want for our spell but was a good test and has taught me a lot about the opacity curves and transparency float slider.
