There were two general methods for making and production of traditional seals in Qajar Era. These methods were defined and designated according to the raw material of the seals i.e stone or metal. So the process of preceding engraving, ranging from the construction of the seals or appearance features should not be known as the methods of seal carving. These characteristics often associated with the professions which are related to the seal making or explains their roles in bureaucratic works. In Qajar Era, stone seals were often made of agate and metal seals were made of brass. However, the phases of seal making before carving, such as text writing, composition and "chap nevisi" were the same in both methods. The tools used for carving metal seals were very simple and delicate and the stone seals were usually engraved by a machine called “Aqiq-kan” ''agate- carver". Actually, Qajar engravers' proficiency in exploiting of these simple tools and their knowledge of relating crafts to carving were quite decisive in making and presenting of high-grade seals in Qajar Era. In this paper, seal engraving styles in Qajar period based on historical - description research and field collection methods, the intervertebral titles brass (steel) and seals agate (stone) have been analyzed.
