Aleksandr says that usually it takes up to a month and a half for him to produce a single bortkha, which is a vessel to keep alcohol or milk products such as liquid yoghurt. In the past when it was used widely, a bortkha also served as an object to indicate the wealth and social status of its owner. Aleksandr shows various sketches of bortkha and ornaments that go with it. He explains that a bortkha is produced as follows. Two pieces of soft pelt are sewed together to make a vessel. In order to give it the required shape, the bortkha is filled with a mix of soil and sand. Decorations are also applied when the pelt is still soft. The bortkha is then dried and smoked on a fire for a day. The neck of the bortkha is made from a white metal such as silver, and rarely from copper or brass. The cork is made from wood. Finally, the bortkha is smeared with a mix of several ingredients, including sheep's fat. As an example, Aleksandr shows one of his bortkhas. He says that he knows how to make a dozen different types. He has produced more than 30 so far.
