Ganchkarlik (plastering and carving special alabaster – ganch) is one of the most ancient types of architectural-decorative arts of Uzbekistan. In the ХХ century its main centers were located in Khiva, Bukhara, Tashkent, Samarkand, Andijan, Namangan and Qoqand. Ganch carving art is indivisibly connected with architectural art than other types of applied folk art. From time immemorial, it has been used for decorating palaces, madrasahs, mosques and houses. The technique of creating a pattern on ganch surface is labor-intensive one. First, on the raw surface draft picture of the future ornamental pattern is drawn. Then, relief pattern is cut along the outline, while the background is deepened and salient parts of the pattern are finished. Also, special skill requires the work on relief pattern, because the effect of perception of the whole carved panel depends on it. As a matter of fact, Uzbek masters have developed many techniques of finishing relief patterns, which make carved panels look more dynamic, their salient and deepened parts more expressive thanks to the effect of light and shade.
