Calcium Sulfate as a desiccant - Will anhydrous work?
Wiki states that Anhydrous CaSO4 is very slow to react with water, almost to the point of not absorbing or mixing. It does state there is another
form of anhydrous, γ-Anhydrite .05H2O, which will react with water and is mentioned as a commercial desiccant.
The difference in temp between the two anhydrites is 180C and 250C as stated by Wiki. I've found a lot of compounds are very slow to decompose at
their stated temp and was wondering if anyone has ever used the pure anhydrous as a desiccant.

We used to use it to remove the water during meat analysis - the pulped sample would be mixed with Pet. Ether and a good dollop of anhydrous calcium
sulphate and shaken. The ether was then analysed for fat content. This was thirty years ago though...
