Works made of copper make up a large part of the Semahat and Nusret Arsel Collection. Copper objects illustrate the culture of bath with examples of wash basins and boxes known as “kildan.” Most of the kitchen equipment is made of copper, and these various tools make up a rich collection. Another richness of the copper collection is that it features works produced in 21 cities including Erzincan, Siirt, Kastamonu, Şanlıurfa, Mardin, Trabzon, Kars, Kayseri, Tokat, Istanbul, Denizli, Konya, Çanakkale, Sivas, Muğla, Erzurum, Bursa, Gaziantep, Diyarbakır, Kahramanmaraş, and Çankırı. The copper ornamentations contain lines, relief motifs, pomegranates on a branch, tulips, various flowers and leaves, geometrical motifs such as crescents and stars, şemse, yarım şemse, salbekli şemse, palmettes, lotus, circles, hexagons as well as animal motifs such as fish, birds, and roosters. Some of the containers which have covers are marked the name of the owner and the date of acquisition. The copper objects are exhibited on all three levels of the Ankara Orchard House.
