 The craftsmen are believed to have been responsible for all the tiles on the imperial buildings until the construction of the Süleymaniye Mosque in the 1550s.Most of the tiles were decorated with coloured glazes using the "cuerda seca" (dry cord) technique, but in a few cases the tiles were underglaze painted in cobalt blue and turquoise.These underglaze tiles were used on the revetments of the facade of the Holy Mantle Pavilion (Privy Chamber) in the grounds of the Topkapı Palace and within the mausoleum of Çoban Mustafa Pasha (d. 1529) in Gebze.
