Q.Bordeaux Mixture and Slaked lime?

Zone Amersham, Bucks UK | Anonymous added on February 14, 2020 | Answered

A bit confused. In your recipe for Bordeaux Mixture you state “Slaked lime is calcium oxide, and once introduced to water, it becomes calcium hydroxide.” But I thought calcium oxide (CaO) is ‘quicklime’ and calcium hydroxide (Ca(OH)2) is ‘slaked lime’ or ‘hydrated lime’. Calcium oxide is quite a reactive sustance and was used for rapidly decomposing corpses!
