Expensive materials were woven in a sophisticated technique, using silver and metal-wrapped silk, to produce a rare and precious type of Ottoman silk fabrics called seraser. Few examples survive from the early period of production dating from the first half of the sixteenth century. They are usually woven in designs and motifs quite different from the typical Ottoman artistic language, organized in narrow horizontal bands of small-scale decoration. Here, blue diamond-like rectangles, each bearing eight-petalled silver blossoms, are framed by red borders composed of two intertwined silver ribbon-like forms. These wider bands alternate with narrower white-ground bands containing blue undulating vines. The overall effect results from the richness of colored silk accented with the silvery sheen of the metal-wrapped thread. While the later seraser pieces were mainly produced for ceremonial robes, the use of the earlier ones still remains enigmatic.
