Another recovery cycle is employed to recycle the calcium used for recausticizing. The calcium carbonate formed in the causticizers is removed by gravity in white-liquor clarifiers or by filtration and washed to remove sodium salts. The weak-wash water, still highly alkaline, is generally recycled to the smelt dissolving tanks.

The recausticizing plant has been recognized as a very important part of the Kraft pulping process.

Finally, a tip from one of those gracious Southern cooks: "Do not rinse grits, ever!" What's indeed missing is the reason. The "Because:". Had a southern cook forbidden me to rinse the grits, I would have guessed it's because of the starch. Just as you thought. Rinsing cleans, moistens the food a bit and removes surface starch when such exists.
