Abstract
Stucco work (gachbori) is one of the most prominent and sophisticated traditional arts of Iran, which has historically been executed using a variety of technical methods. Due to the inherent fragility of gypsum and the impact of both environmental and human factors that contribute to the deterioration of historic plasterworks, the conservation and restoration of these elements—particularly through the revival of forgotten or seldom-used techniques—are essential for preserving and transmitting cultural heritage to future generations.
One such technique is the creation of openwork stucco decorations, which are freestanding ornaments executed in a pierced style without a backing layer. This method is especially prevalent in the central regions of Iran, notably in the historic houses of Kashan, where lattice windows (rozans) filled with colored glass are a distinguishing feature. From a technical standpoint, the decorative work is carried out by applying gypsum over a temporary support; once the support is removed, the cut-out patterns are completed from the rear with stained glass.
This article presents a detailed account of the reconstruction and restoration process of one such gypsum lattice window in the Abbasi House of Kashan. Through a practical and field-based approach, the authors replicate and document the historical construction techniques and restoration steps involved in reviving this architectural ornament, offering insights into the craftsmanship and methodology behind these delicate works.
