Well it says lab grade,I believe Randy Holmes-Farley says in his article to use Food grade or Lab grade.I'll look for the first article he wrote about it and post a link if I can find it.

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.
