Cuerda seca

Tile from Isfahan in Iran, 17th century

Cuerda seca (Spanish for "dry cord") is a technique used when applying coloured glazes to ceramic surfaces.

When different coloured glazes are applied to a ceramic surface, the glazes have a tendency to run together during the firing process. In the cuerda seca technique, the water-soluble glazes are separated on the surface by thin lines of a greasy substance to prevent them running out of their delineated areas. A dark pigment such as manganese carbonate is usually mixed with the grease to produce a dark line around each coloured area.^[1]

In central Asia tiles were manufactured using the cuerda seca technique from the second half of the 14th century.^[2] The introduction of different coloured glazes is recorded in the mausoleums of the Shah-i-Zinda necropolis in Samarkand. In the 1360s the colours were restricted to white, turquoise and cobalt blue but by 1386 the palette had been expanded to include yellow, light-green and unglazed red.^[3] Large quantities of cuerda seca tiles were produced during the Timurid (1370–1507) and Safavid (1501–1736) periods.^[4]

In the 15th century Persian potters from Tabriz introduced the technique into Turkey and were responsible for decorating the Yeşil Mosque in Bursa (1419-1424).^[5] Within the Ottoman Empire cuerda seca tilework fell out of fashion in the 1550s and new imperial buildings were decorated with underglaze-painted tiles from Iznik. The last building in Istanbul to include cuerda seca tilework was the Kara Ahmed Pasha Mosque which was designed in 1555 but only completed in 1572.^[6][7]
