Kitchen Salt. Flake grainer, kiln-dried, screened, ground and dried solar, or 

 rock-salt screenings. Commonly called "table salt." 



Shaker Salt. Vacuum pan, grainer flake, finest kiln-dried, small screened and 

 usually powdered with carbonate of magnesia to keep it free-running. For dining- 

 table use. 



Fishery Salt. Pure, coarse, flaky steam-grainer salt, which is free from calcium 

 and magnesium, should be used. The flakes take up the fish juices rapidly, allowing 

 a faster rate of penetration. Magnesium and calcium in fish salt cause "case-harden- 

 ing," which cures the outer parts but gives less preservative action inside, used for 

 dry-salting butts of cod, haddock, cusk, pollock, etc.
