Fritware in the context of "Glue"

Iznik pottery, or Iznik ware, named after the town of İznik in Anatolia where it was made, is a decorated ceramic that was produced from the last quarter of the 15th century until the end of the 17th century. The Ottoman Turkish motivation for creating İznik ware was to imitate the prestige and symbolic value of Chinese porcelain, not its specific decorative designs. While their conceptual origin lies in Chinese blue-and-white porcelain, their decorative design is a distinct Ottoman adaptation of the International Timurid style. This adaptation is marked by a transformation from the prototype's languid quality to a more forceful and contained design, distinguished by its intensity and three-dimensional feel. Technologically, these wares are unique, differing from the methods used for contemporary Iranian pottery and Ottoman architectural tilework. This distinct manufacturing process is thought to be an invention of Anatolian potters.

İznik was an established centre for the production of simple earthenware pottery with an underglaze decoration when, in the last quarter of the 15th century, craftsmen in the town began to manufacture high quality pottery with a fritware body painted with cobalt blue under a colourless transparent lead glaze. The change was almost certainly a result of active intervention and patronage by the recently established Ottoman court in Istanbul who greatly valued Chinese blue-and-white porcelain.

Decoration in Ottoman architecture takes on several forms, the most prominent of which include tile decoration, painted decoration, and stone carving. Beginning in the 14th century, early Ottoman decoration was largely a continuation of earlier Seljuk styles in Anatolia as well as other predominant styles of decoration found in Islamic art and architecture at the time. Over the course of the next few centuries, a distinctive Ottoman repertoire of motifs evolved, mostly floral motifs, such as rumî, hatayî, and saz styles. Calligraphic inscriptions, most characteristically in a thuluth script, were also a mainstay. From the 18th century onward, this repertoire became increasingly influenced by Western European art and architecture and went as far as directly borrowing techniques and styles from the latter.

Ottoman tiles attained a prominent role in decoration. Starting in the early 15th century, cuerda seca tiles in vivid colours were widely used in various buildings, using mostly vegetal arabesque motifs, of which the most dramatic early example is the Green Mosque and Green Tomb in Bursa (circa 1424). Various examples of tilework from this century seem to show possible Iranian influence and connections to Timurid art. A distinctive style of blue-and-white fritware, influenced by Chinese motifs and often attributed to an early stage of Iznik tilework, is evidenced by the late 15th century and characterizes the early 16th century. Iznik tiles became highly favoured during the rest of the 16th century and reached their artistic peak in the second half of the century. They featured stylized floral and vegetal motifs in blue, white, red, and green colours. The Iznik industry declined by the end of the 17th century, with production of lower-quality tiles shifting to Kütahya. In the early 18th century, a revival of tile art was attempted through the establishment of a new workshop at Tekfursaray in Istanbul, but ultimately the industry faded after this and tile decoration lost its importance.

Mina'i ware is a type of Persian pottery, or Islamic pottery, developed in Kashan in the decades leading up to the Mongol invasion of Persia and Mesopotamia in 1219, after which production ceased. It has been described as "probably the most luxurious of all types of ceramic ware produced in the eastern Islamic lands during the medieval period". The ceramic body of white-ish fritware or stonepaste is fully decorated with detailed paintings using several colours, usually including figures.

It is significant as the first pottery to use overglaze enamels, painted over the ceramic glaze fixed by a main glost firing; after painting the wares were given a second firing at a lower temperature. "Mina'i" (Persian: مینایی), a term only used for these wares much later, means "enamelled" in the Persian language. The technique is also known as haft-rang, "seven colours" in Persian. This term was used by the near-contemporary writer Abu al-Qasim Kasani, who had a pottery background. This technique much later became the standard method of decorating the best European and Chinese porcelain, though it is not clear that there was a connection between this and the earlier Persian use of the technique. As in other periods and regions when overglaze enamels were used, the purpose of the technique was to expand the range of colours available to painters beyond the very limited group that could withstand the temperature required for the main firing of the body and glaze, which in the case of these wares was about 950 °C.
