The polarisation effects are way much less due to the additional small size (relative) of the fluorine anion (low polarisability). This leads me to conclude that calcium fluoride is highly ionic in nature, and should be soluble in water. http://www.columbia.edu/~ps24/PDFs/Mineral%20Solution%20Equilibria%20in%20Sparingly%20Soluble%20Mineral%20Sys.pdf how to smoke a 6lb brisket
