Platinum melting point 1,772°C
Platinum is found in nature alloyed with the other metals of the so-called platinum group, found in group VIII of the periodic table; the other five metals in this group are iridium, osmium, palladium, rhodium, and ruthenium. These metals are found in alluvial deposits in Russia, South Africa, Colombia, and Alaska.
Platinum and the related metals are recovered commercially as a byproduct of the refining of nickel ores mined near Sudbury, Ont., Canada; from gold mines in South Africa; and from the alluvial deposits in Russia. There is no routine method for separating platinum from other metals; it is usually recovered by complex chemical methods.
Platinum has many uses. Its wear- and tarnish-resistance characteristics are well-suited for making fine jewelry. Platinum and its alloys are used in surgical tools, laboratory utensils, electrical resistance wires, and electrical contact points. The most important of the alloys are those with iridium.
Cleaning Platinum - Use any jewelry cleaner that is gold and/or platinum jewelry specific. Also warm water and facial soap. Tap dry with cotton cloth. Do not air-dry. High powered steaming okay. Periodic polishings on polishing wheel is acceptable.
Please Note - The buffing/polishing wheel will remove metal so please be careful. Only buff your jewelry when it is absolutely neccesary. Over buffing will thin out your rings, bracelets, necklaces, watch bands and anything else that the wheel comes in contact with
