Colored gold

Pure gold is slightly reddish yellow in color, but colored gold in various other colors can be produced.

Colored golds can be classified to three groups:

Pure 100% gold is 24 karat by definition, so all colored golds are less than this, with the common being 18K (75%), 14K (58%), and 9K (38%).

Alloys

White gold

White gold is an alloy of gold and at least one white metal, usually nickel, manganese or palladium. Like yellow gold, the purity of white gold is given in karats.

White gold's properties vary depending on the metals and proportions used. As a result, white gold alloys can be used for many different purposes; while a nickel alloy is hard and strong and therefore good for rings and pins, gold-palladium alloys are soft, pliable and good for white gold gemstone settings, sometimes with other metals like copper, silver, and platinum for weight and durability, although this often requires specialized goldsmiths. The term white gold is used very loosely in the industry to describe karat gold alloys with a whitish hue. It is a common misconception that the color of the rhodium plating, which is seen on many commercial pieces, is actually the color of white gold. The term "white" covers a large spectrum of colors that borders or overlaps pale yellow, tinted brown, and even very pale rose. The jewelry industry often conceals these off-white colors by rhodium plating.

White Gold: War in Paradise

White Gold: War in Paradise (Xenus II: Белое золото, Xenus II: White Gold) is the sequel to the 2005 video game Boiling Point: Road to Hell. White Gold was developed by the Kiev-based game studio Deep Shadows. The Microsoft Windows version was released in CIS territories by Russobit-M on October 24, 2008, with the Xbox 360 and other Windows regions seemingly cancelled. The game runs on the Vital Engine 3, which also powers The Precursors. In December 2010, an English version was made available via digital distribution on GamersGate. The game is also available for purchase via online retailer Beamdog.

Setting

The game's events take place in water-separated islands in the Caribbean basin, in contrast to the single land mass called Realia in Boiling Point. The hero arrives on the islands to investigate a series of mysterious events connected with poisonous cocaine. He finds himself in the middle of a socially unstable and politically volatile environment, with 7 different factions including Civilians, Government, Mafia, Guerrillas, Bandits, Natives and CIA operatives. The protagonist is called Saul Meyers like the hero in Boiling Point, but he looks younger so story wise the game may actually be some kind of prequel to Boiling Point.

Asbestos

Asbestos (pronounced /æsˈbɛstəs/, /æzˈbɛstəs/ or /æzˈbɛstɒs/) is a set of six naturally occurring silicate minerals, which all have in common their eponymous asbestiform habit: long (roughly 1:20 aspect ratio), thin fibrous crystals, with each visible fiber composed of millions of microscopic "fibrils" that can be released by abrasion and other processes. They are commonly known by their colors, as blue asbestos, brown asbestos, white asbestos, and green asbestos.

Asbestos mining existed more than 4,000 years ago, but large-scale mining began at the end of the 19th century, when manufacturers and builders began using asbestos because of its desirable physical properties:sound absorption, average tensile strength, its resistance to fire, heat, electrical and chemical damage, and affordability. It was used in such applications as electrical insulation for hotplate wiring and in building insulation. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. These desirable properties made asbestos a very widely used material, and its use continued to grow throughout most of the 20th century until the knowledge of carcinogenic effects of asbestos dust caused its effective demise as a mainstream construction and fireproofing material in most countries.
