We can divide the vases in two different types: the first one are the pots that have specific usefulness, and the second one are the vases that not have a specific role, but are created only for decorating the environment.
In the first one category we can talk about pots like Alabastron, used in the ancient World, especially in Greece and Egypt, for holding perfume or oil. Another kind of vase is called Amphora, a ceramic or terracotta pot with two handles, used to transport wine, oil, fish sauce, jam, honey, and more. The first Amphora is appeared in 15th century Before Christ on Syrian coast.
Another kind of pot is Situla, iron vase that have the shape of a bucket. The Situla was diffused in Iron Age populations, like Etruscan, Celts, and Germanic cultures.
In modern age we have a differents kinds of vases, but the most spread are the ornamental pots.
In this category are very spread the glass pots. The most famous are probably the decorated vases of Murano, created with technique of blowing glass.
This kind of pots does not have a specific role, but they are really beautiful. For this reason are used to decorate the environment and especially the important rooms.
Glass is product created from silicon mixtures (quartz, sand, sodium, iron, calcium, and more). To create coloured glass, the artisan add some metallic oxides for different colors.Cobalt for blue, Copper for red, and so on.
Glass and vases production of Murano has not changed during the centuries. Nowadays there aren't new techniques to make the special glass of Murano: the result depends most of all on the expertise and the artistic skills of the glass artisan.
