Sterling silver

Sterling silver is an alloy of silver containing 92.5% by mass of silver and 7.5% by mass of other metals, usually copper. The sterling silver standard has a minimum millesimal fineness of 925.

Fine silver, for example 99.9% pure silver, is generally too soft for producing functional objects; therefore, the silver is usually alloyed with copper to give it strength while preserving the ductility and appearance of the precious metal. Other metals can replace the copper, usually with the intention of improving various properties of the basic sterling alloy such as reducing casting porosity, eliminating firescale, and increasing resistance to tarnish. These replacement metals include germanium, zinc and platinum, as well as a variety of other additives, including silicon and boron. Alloys such as argentium silver have appeared in recent decades.

Etymology

One of the earliest attestations of the term is in Old French form esterlin, in a charter of the abbey of Les Préaux, dating to either 1085 or 1104. The English chronicler Orderic Vitalis (1075 – c. 1142) uses the Latin forms libræ sterilensium and libræ sterilensis monetæ. The word in origin refers to the newly introduced Norman silver penny.

The Mist

The Mist is a horror novella by the American author Stephen King, in which the small town of Bridgton, Maine is suddenly enveloped in an unnatural mist that conceals otherworldly monsters. It was first published as the first and longest story of the horror anthology Dark Forces in 1980. A slightly edited version was included in King's collection Skeleton Crew (1985). The story is the longest entry in Skeleton Crew and occupies the first 134 pages. To coincide with the theatrical release of the film based on the novella, The Mist was republished as a stand-alone paperback book by Signet on October 2, 2007.

Summary

The morning after a violent thunderstorm, a thick unnatural mist quickly spreads across the small town of Bridgton, Maine, reducing visibility to near-zero and concealing numerous species of bizarre creatures which viciously attack anyone and anything that ventures out into the open.

The bulk of the story details the plight of a large group of people who become trapped while shopping in the town supermarket, among them a commercial artist named David Drayton (the protagonist and narrator), David's young son Billy, and their estranged neighbor Brent Norton, who accompanied them into town after a tree smashed Brent's car. Amongst others trapped in the market are a young woman named Amanda Dumfries and two soldiers from a nearby military installation, home to what is referred to as "The Arrowhead Project". The two soldiers' eventual joint suicide lends some credence to the theory that this Project was the source of the disaster.

Mist

Mist is a phenomenon caused by small droplets of water suspended in air. Physically it is one instance of a dispersion. It is most commonly seen where warm, moist air meets sudden cooling, such as in exhaled air in the winter, or when throwing water onto the hot stove of a sauna. It is often created artificially with aerosol canisters if the humidity and temperature conditions are right. It can also occur as part of natural weather, when humid air cools rapidly, for example when the air comes into contact with surfaces that are much cooler than the air.

The formation of mist, as of other suspensions, is greatly aided by the presence of nucleation sites on which the suspended water phase can congeal. Thus even such unusual sources as small particulates from volcanic eruptions, releases of strongly polar gases, and even the magnetospheric ions associated with polar lights can in right conditions trigger the formation of mist.

Description

The only difference between mist and fog is visibility. The phenomenon is called fog, if the visibility is one kilometre (1,100 yards) or less (in the UK for driving purposes the definition of fog is visibility less than 100 metres (UK Highway Code rule 226), for pilots the distance is 1 kilometre). Otherwise it is known as mist. Seen from a distance, mist is bluish, and haze is more brownish.
