I talked to a lithium products supplier this morning. He called after a left an e-mail and filled me in on lithium bromide and lithium chloride. The bromide stuff won't work because it's soluble in glycerin. But the lithium chloride is only soluble in water, so I'll tray to get some of it. By the way, the calcium chloride I tried managed to separate the oil and water better than just letting it sit, but formed a thick sludge on the bottom. I'll keep working on it. Maybe a higher temp?
