Tabriz
Tabriz is one of the oldest rug weaving centers and makes a huge diversity of types of carpets. The range starts at Bazaar quality of 25 raj (Number of knots per length of 7 cm of the widths of the rug) and on up to the incredibly fine 110 raj. Raj are the units of knot density (it shows the fitness of the rug which based on the number of strings used for the foundation of the rug). Strings materials are usually made of cotton or silk which is used for very fine rugs.
Tabriz has one of the most diverse displays of designs from medallion, Herati/Mahi, Coumbat, to figural, pictorial, and even 3-d shaped rugs.
Tabriz has been a large and worldwide famous carpet making center in the Iran and the world.
The Persian carpets are an essential part of Persian art and culture and they among the most famous in the world.
For the more elaborate curvilinear designs, the patterns are carefully drawn to scale in the proper colours on graph paper. Each square thus becomes a knot, which allows for an accurate rendition of even the most complex design. Designs have changed little through centuries of weaving.
Classic Persian carpets are made on vertical looms. Vertical looms are undoubtedly more comfortable to operate. These are found more in city weavers and sedentary peoples because they are hard to dismantle and transport. There is no limit to the length of the carpet that can be woven on a vertical loom and there is no restriction to its width.Also the conditions of manufacture are such that allow more finer and perfect creations.
