Most silver objects of everyday use are in fact Sterling Silver, which contains usually 7.5% of copper to improve its hardness and utility. The corrosion is often that of the copper component, and is made of various oxides, carbonates, sulphides and so on.
Pure silver in fact tarnishes less, though it does still attain a patina of oxide.

Why do vessels made of metals lose shine after few days?
Most metals lose their shine as they react with gases in the atmosphere or in a liquid.. The surface layer may react to fom an oxide, hydrated oxides, sulfide, sulfates, carbonates. Generally ths process makes the surface dull and it may get pitted. The process is called corrosion when it is iron rusting and tarnishing when it is silver forming black silver sulfide or copper forming a mixture of greenish products, "patina" whose composition depends on the location.Some metals do not lose their shine. Common examples are gold and platinum which are used as jewellery. Aluminium still looks shiny but there is thin layer of aluminium oxide which prevents the reactive aluminium metal from corroding.
Are metals always shiny?
No. None of the Group 1 and Group 2 elements of the periodic table, the alkali and alkali earth metals respectively, stay shiny when exposed to air. They all react with moisture in air, and they tarnish quickly. A number of other metals will not stay shiny, either. Iron can be polished, but it will oxidize (rust) if left in air. Some metals will not react with air or the moisture in it, and some will. The results are mixed in that there are a lot of transition metals (Groups 3 through 12 on the periodic table), and each one would have to be evaluated independently (or with its "group mates") to discover if it would stay shiny. Links are provided to some relevant Wikipedia articles. The links are to the groups of metals, and each element in the Group chart is a hyperlink to that element. It should make it easy to do a quick search of the metals to get a complete answer, if that is what is desired.
