Drierite® is the brand name and registered trademark of a variety of desiccants made from anhydrous calcium sulfate (anhydrite). Some varieties contain less than 2% cobalt(II) chloride, a moisture-sensitive color indicator that shows when that material's activity has been depleted. Drierite is manufactured in the USA by the W.A. Hammond Drierite Co., Ltd., founded by W. A. Hammond and headquartered in Xenia, Ohio.[1]
After drierite has been exposed to moisture, it can be regenerated by baking at 210°C for an hour.[2]
