A related development to the shifting economic conditions was the establishment of Karkhanas, or small factories and the import and dissemination of technology through India and the rest of the world. The use of ceramic tiles was adopted from architectural traditions of Iraq, Iran, and Central Asia. Rajasthan's blue pottery was a local variation of imported Chinese pottery. There is also the example of Sultan Abidin (1420–1470) sending Kashmiri artisans to Samarqand to learn book-binding and paper making. Khurja and Siwan became renowned for pottery, Moradabad for brass ware, Mirzapur for carpets, Firozabad for glass wares, Farrukhabad for printing, Sahranpur and Nagina for wood-carving, Bidar and Lucknow for bidriware, Srinagar for papier-mache, Benaras for jewellery and textiles, and so on. On the flip-side encouraging such growth also resulted in higher taxes on the peasantry.
