The arts of the Abbasid Caliphate included fabrication of ceramics, textiles, glassware, and decorated manuscripts. Ceramics became one of the most important art forms and the invention of lustreware in this industry was a major innovation that influenced ceramic art throughout the region. This technique likely originated in glassware, which also became a more significant industry. Another major art form was calligraphy, with variations of Kufic being the main early style of script, along with the production of Qur'an manuscripts. An important textile industry existed, notably in the production of inscribed tiraz pieces. While metalwork of gold and silver has rarely survived, some silver dishes from Iran show derivations from Sasanian types, while bronze and copper alloy pieces of different types have also been found. Painting and stucco were important forms of decoration in architecture.
