Safe preservation of the trailing ornamentations of the historical domes of Isfahan to these days is a well-known fact for the architects and artists of the field. A vast knowledge and mastery are required from the earliest phases of tile-baking up to the artistic executions of faience-mosaics as well as the supply and processing of gypsum, let alone a firm grasp of traditional geometry due to a complicated course of construction and restoration of faience-mosaics of the domes. Better conservation and maintenance of the architecture is demanded due to the historical, moral, and aesthetical significance of the tiled domes of Isfahan, i.e., their historical symbolism. One should firstly gain an acquaintance with the restoration methods of tiling from the earliest time to present. The study relied on the restoration process of three main historical domes of Isfahan, namely those of Jame-Abbasi and Sheikh Lotfollah mosques and of Madrese-ye chahar-Bagh.
Motalebi et al. (Mon,) studied this question.
