Limestone can be purchased in bulk (truckloads) or in bags (50 pound bags) and can be applied as a dry powder or mixed with water as a wet slurry. A wellmixed slurry of lake water and finesized particles of limestone is more soluble than a dry powder. Buy the smallest particle size of limestone available that is cost effective.
To make chalk, limestone is first quarried, generally by an open pit quarry method. Next, the limestone must be crushed. ... Process Quarrying limestone ... (the procedure is similar to sifting and baking powder together before adding liquid, as in a cake recipe). ...
The hydration process, when done with just the right amount of water for chemical reaction, is called dry hydration process. The product of dry hydration process is hydrated lime which is a dry powder and in which the oxides are converted to hydroxides.
