Kumgan is a jug for water with a spout, handle, and lid, made of brass, silver, or clay. The name is used in Central Asia and originates from Turkic quman. Also known under the Persian name aftabeh (), historically they were used in Asia primarily for washing oneself and hands, following the tradition of performing natural needs in the Islamic East. When they arrived to Russia from central Asia in 16th–17th centuries, their purpose changed and they had become a vessel for drinking and they started being made of less noble metals.КУМГАН, Большой Энциклопедический словарь 2000Copper Kumgan (Water Ewer)
This word was recorded in Russian by Vladimir Dal as hand-washing vessel, also colloquially called кубган, кулган, курган.Кумган
The word quman also gave rise to the Ukrainian jug ("little quman"), which was used for drinks, such as horilka in the past, but now it is mainly of decorative use. It had a peculiar doughnut shape. This kind of jug was called in Russia, literally "a jug for kvass".Квасник, Great Soviet Encyclopedia
