At a Greek symposium, kraters were placed in the center of the room. They were quite large, so they were not easily portable when filled. Thus, the wine-water mixture would be withdrawn from the krater with other vessels. In fact, Homer's Odyssey[1] describes a steward drawing wine from a krater at a banquet and then running to and fro pouring the wine into guests' drinking cups. The modern Greek word now used for undiluted wine, krasi (κρασί), originates from the krasis (κράσις, i.e. mixing) of wine and water in kraters.[2] Kraters were glazed on the interior to make the surface of the clay more impervious for holding water, and possibly for aesthetic reasons, since the interior could easily be seen.
