Bill,
Well, I am pretty sure that they do NOT sell you quicklime (Calcium
Oxide). No way!!
What you are almost certainly getting is slaked lime, which is an
industrial product obtained by adding water to quicklime and is then
ground down to a white powder. In common parlance this is also often
referred to as garden lime.
