Beautiful ceremonial glass inca "kero" polychrome wood

Description

A Kero (from Quechua: qiru, wood, often written as kero) is a ceremonial vessel, usually made of wood, with a frustoconical shape, wider at the mouth than at the base, typical of several surandine cultures. In documents of the XVIII and XIX centuries were also denominated like drinker of palo, glass of palo and calyx of wood.
Is an ancient Incan vessel for drinking liquids such as alcohol, or more specifically, chicha. They can be made of wood, ceramics, silver or gold, used traditionally in the Andes fiestas.
Keros were decorated in the first layer with a surface pattern on the surface of the glass, after filling the pattern with a durable, water resistant resin blend of the plant and pigments such as cinnabar. The finely incised lines would meet at the intersection points that collaborated to create shapes like triangles, squares and diamonds. The shapes are organized into two to four horizontal registers.
One of them is usually decorated with luxurious, hand-painted geometric designs that follow traditional techniques. Others, however, can be painted with narrative scenes that could possibly be true historical events. Many times they are solitary, other times they are found together with other Peruvian ceramics. Kero production reached its apogee between 1300s.
The Incas made these vessels typically in identical pairs. This followed the custom which required two people to drink together and both qirus in the pair would have identical size, shape and decoration. These pairs are normally used for toasting ceremonies and also given along with textiles as gifts as a sign of Inca bounty.
