A cast silver bar is made through traditional refining processes. After the silver is melted down it is poured into a prefabricated mold that is constructed of heat-resistant molds. The silver is left to cool in the mold to create the finish shape. Cast silver bars most commonly have designs that are stamped incuse into the surface of the product.
Obverse designs on the 100 oz Nadir Refinery Silver Bars include the only markings you will find on the products. These large silver bars have inscriptions stamped across the horizontal field of the bar. These markings include the Nadir Refinery symbol in the upper-left, the weight in the upper-right, the purity in the lower-left, and the serial number in the lower-right field. In the center of the bar is a stamp with the assayers mark.
Reverse fields of 100 oz Nadir Refinery Silver Bars are left blank on purpose. Cast silver bars traditionally have designs and inscriptions on just one side. Both sides of the bar may feature textures and visuals that reflect the texture of the silver as it cooled in the mold. These particular cast silver bars are rectangular in shape, but have one surface that is larger in surface area than the other.
The Nadir Metal Refinery began in 1967 in a modest jewelry recycling workshop by Nadir Tütüncü. By 1975, Tütüncü began precious metals refining. Ten years later, he founded Nadir Trading, which became Nadir Metal Refineri San. ve Tic. Ltd. in 1993. The company faced high demand, which made it expand into a full refinery on Turkish soil. After forming a partnership to gain technological advancement, they saw another name change in 1999. This refinery became accredited in 2001, then five years later became a joint-stock company under its name today: Nadir Metal Rafineri San ve Tic. A.Ş. Today it is accredited by the Istanbul Gold Exchange, Dubai Stock Exchange, and LBMA. In addition to refining, recycling, and laboratory operations, Nadir Metal strikes precious metals in the forms of gold, silver, platinum, palladium, and rhodium.
