There are two ways to make black tea -- the orthodox method and the CTC ("Cut, Tear, Curl") method.Both are similar in the five steps they take, except the orthodox method is mostly done by hand, while the CTC method is done by machine.Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes.Redox reactions include all chemical reactions in which atoms have their oxidation state changed; in general, redox reactions involve the transfer of electrons between chemical species.

Without milk, the drink has a reddish brown color and a particularly bold taste.After electrons were discovered, chemists became convinced that oxidation-reduction reactions involved the transfer of electrons from one atom to another.From this perspective, the reaction between magnesium and oxygen is written as follows.Oxidation and reduction are therefore best defined as follows.Oxidation occurs when the oxidation number of an atom becomes larger.
