Calcium Oxide = Quicklime

Quicklime can set fire to wood and paper, so it's usually sold with water added as slaked lime, calcium hydroxide.

Lime water, which we used in school to test for carbon dioxide, is an aqueous solution of calcium hydroxide.

I've heard people talk about buying lime for the garden but it's impossible for this to be calcium oxide because of the fire risk. So garden lime must be calcium hydroxide, which is calcium oxide with water added like whitfield said.
