The "Clogs of the Kaaba" at the Iran Carpet Museum is a pair of metal/ copper alloy shoes by Parviz Tanavoli for an outdoor installation. The work is part of a memorial chapel designed minimalist style within the museum’s grounds. The clogs are crafted to a life-size scale, with their surfaces textured with fine and delicate grooves to enhance their aesthetic and visual appeal. The artist has also applied a dark artistic patina to the surface of the clogs. The interior of the clogs has accumulated dust, soot, and debris from the surrounding greenery. Additionally, prolonged exposure to environmental conditions such as annual rainfall, seasonal temperature variations, and urban pollutants such as acid rain has affected their condition on the ground. The surface of the clogs shows green corrosion products and carbonate deposits. the aim of this operation is to stabilize the clogs and prevent further exposure to harmful urban environmental factors. In order to evaluate and document the current condition, digital photography was conducted on both a macroscopic and microscopic scales. Surface sediment removal was carried out using manual mechanical methods with a scalpel and ultrasonic device. The poultice method was applied in a controlled and limited manner to remove thick sediments using Rachel's salt solution and%2 hydrochloric acid. To protect the surface, a %3 BTA (benzotiazol: C6H5N3) solution was used, followed by a coating of epoxy polyamide solution.
