This is another series of shots of one of the truly great mosques in Bursa the Yesil or Green (1424) Mosque. It has a wealth of great tiles and carving, apart from just being good architecture.I visited the mosque once again in December 2006. I used flash to bring out more natural colours on the great tilework. Reflection caused some trouble, overall I think the result is acceptable.

In the back part, on either side of the corridor leading from the entrance to the main room, are two much smaller elevated rooms, with wonderful tiles all around. Some damage is visible when looking up (has water somehow deteriorated the quality of the glazing?).

To avoid glare from the flash I took an awkward picture.

Generally the ceilings in mosques are not tiled like the walls, but painted. Not here, however.
These tiles were locally produced, by artisans from Tabriz (Iran), under the supervision of Ali bin İlyas Ali, a ‘nakkaş’ (painter-designer) from Bursa, who had been sent to Samarkand by Timurlenk in 1402. Most tiles were made using the so-called ‘cuerda seca’ technique, followed by ingenious gilding patterns.

Cuerda seca: A brilliant but short lived episode in the history of Anatolian ceramic production was the appearance of tiles decorated in the ‘cuerda seca’ (="dry cord") technique. In the ‘cuerda seca’ process, thin bands of waxy resist maintain color separation between glazes during firing, but leave behind "dry cords" of unglazed tile. This technique seems to have been introduced to Turkey from Iran as early as the fourteenth century. These tiles are often distinguished by their curving shape.
