Slake the lime slowly so as to get a smooth
Dissolve the copper sulphate (bluestone) in twenty-five gallons of water. Slake the lime slowly so as to get a smooth, thick cream. Never cover the lime with too much water. After thorough slaking add twenty-five gallons of water. When the lime and the bluestone have dissolved, pour the two liquids into a third vessel. Be sure that each stream mixes with the other before either enters the vessel. Strain through a coarse cloth.
