Most of the copperware was forged on the territory of modern Daghestan; the services of wandering masters were also in high demand. Tinkers walked the roads of the Northern and Southern Caucasus equipped with all the necessary implements: they took with them, little hammers and anvils, chasing and engraving tools, and whatever was needed to repair dishware. 

 
While being forged copperware was tinned both inside and outside. It protected the metal from ambient impacts and adverse processes such as corrosion. To make it more hygienic for use, the inner surface was coated with wax-based mastic. 

 
Copperware was often decorated with engraving or chasing, therefore it was hard work making it, and such goods were quite expensive. Only well-to-do Adyghes could afford to buy whole sets.

Spread of kumgans and other ritual vessels and dishes in Circassia was a result of Islam having been introduced in the Adyghe culture. Not a single Mohammedan prayer, salah, was allowed without a special ablution as only those who have performed a special purification ritual could present themselves to the Allah. 

Sunni Mohammedanism in Circassia was promoted by Crimean Tatar khans and Turkish missionaries. The Adyghes resisted the new religion being imposed on them, as well as resisting the Ottoman domination in their land; therefore Islamic institutions had failed to firmly establish themselves by the 19th-20th centuries. Even identifying themselves as members of the Muslim world, Circassians continued to live in accordance with their own ancient ideas and values. Out of all religious prescriptions, they adhered only to some important rituals, such as a funeral ceremony.
