Calcium Chloride In The Oven @ 392 F

 Martin Brugard who made Bru'n Water has a method of getting the moisture out of calcium chloride. 

Toss on a baking sheet and pre-heat the oven to 392F. Bake for an hour and it should dry it out so you can get true measurements when weighing it out. May as well try it now and if it fails, I have time to buy some new stuff to use in the future. I don't have a lot.

Doing this on Nov. 28. 2024. Done. Yes, it was quite dry. It must of picked up a ton of moisture  when ever I bought it. I vacuumed sealed it. I need to buy more in Feb. 2025.
