the grain is a region within a solidified metal where the crystalline structure of the atoms is relatively perfect. The entire structure of the metal is made up of such grains. During cooling the grains are formed by growing larger from chance joining of atom pairs or from an impurity. As the grains grow they meet each other and the crystalline structure ends at these boundaries. hope this helps you a bit more

you pour the pot of substance into the mixture of chloride with benzoic acid, then you mix it with a spatula of Sulphurate.
Bring to the boil add a sprinkling of herbs then serve with a portion of Tatar Sauce
