Calcium Sulfate with trace methanol = ooblek!
Post Body
Cleaning up a potentially useful side product of a previous reaction, getting ready to cook off all of the moisture to use it as a dessicant.
I pulled a vacuum on it for a few minutes after washing with water, then a few passes of dry methanol.
It rather politely thumped out of the fritte into a dish, then over the next new minutes, slowly melted into a pool, which I've been poking at while I decide how I want to go about heating it up to it's gamma anhydrite point.
