In the second decade of the 15th century after Amir Timur’s death, during the reigns of his successors, the[br]glazed decoration was only used to embellish and accentuate the architectural forms of a building, not longer as an all-covering canvas.[br]Extensive wall surfaces were decorated with large geometric designs against a background of brick facings consisting of small glazed bricks, which could be easily read from a considerable distance.[br]Examplary are the madrassas on the Samarkand Registan, the Bibi Khanum mosque and the Gur Emir mausoleum both in Samarkand too.[br]In the pictures below you can clearly see how coloured glazed bricks are arranged horizontally or vertically to create horizontal, vertical and even oblique lines in kufic calligraphy.[br][br]
