I couldn't find the article where he talks about Calcium Hydroxide,but this is what he says about Calcium Cloride.

"Any FCC (food), USP (pharmaceutical) or BP (pharmaceutical) grades of calcium chloride should be suitable."-Randy Holmes-Farley.

I would think the standards would be the same for both.

FCC and USP are 95-100% pure Ca(OH)2 whereas your stuff is only 73%..I wouldn't do it.
