If you look at the stem of an artichoke you will see a ring, with tough green bark (for want of a better term) surrounding a paler green heart.The bark is not good to eat, and you should remove it with a paring knife, leaving the heart of the stem, which is good to eat.ere we were going to need sliced artichokes, and trimmed the stem of the artichoke leaving about an inch (2.5 cm) below the petals.

Silicon is an important constituent of electrical steel, modifying its resistivity and ferromagnetic properties. The properties of silicon can be used to modify alloys with metals other than iron. Metallurgical grade silicon is silicon of 95â99% purity. About 55% of the world consumption of metallurgical purity silicon goes for production of aluminium-silicon alloys (silumin alloys) for aluminium part casts, mainly for use in the automotive industry.
