HYDRATED LIME. 



Definition. — When quicklime is slaked, by whatever process, whether in 

 the simple mortar box by adding water by the bucketful and stirring with 

 a hoe, or whether the lime and water are automatically weighed out in definite 

 parts and the mass is stirred by machinery, the chemical principle involved is 

 the same, viz., quicklime plus water becomes slaked lime, or hydrated lime — 



Ca0-fH20=Ca(0H)2.
