Porcelain tile

Porcelain tiles are ceramic tiles commonly used to cover floors and walls, with a water absorption rate of less than 0.5 percent. They can either be glazed or unglazed.

History

Although porcelain has been used for making tiles for many years, only modern production methods and quantities has made the porcelain tile available for the average householder in recent years.

Production

Large-scale production of porcelain tile is undertaken in many countries, with the major producers being China, Italy, Spain and Turkey. There are also countries undertaking small-scale production, such as Australia and strong growth in Brazil.

The hardness of the tile can be rated from zero to five according to ISO 10545-7 (also, ASTM C1027) test for surface abrasion resistance of glazed tile, and this can be used to determine suitability for various end use conditions.

Polished Porcelain tiles

The dense, hard surface of porcelain has made polishing a viable alternative to a glazed surface. This means that a tile can be fired, then a polish cut into the surface, creating a shine without a glaze.

Short film

A short film is any film not long enough to be considered a feature film. Although no consensus exists as to where that boundary is drawn, the Academy of Motion Picture Arts and Sciences defines a short film as "an original motion picture that has a running time of 40 minutes or less, including all credits". The term featurette originally applied to a film longer than a short subject, but shorter than a standard feature film.

The increasingly rare term short subject means approximately the same thing. An industry term, it carries more of an assumption that the film is shown as part of a presentation along with a feature film. Short is an abbreviation for either term. Short films are often screened at local, national, or international film festivals and made by independent filmmakers for non profit, either with a low budget or no budget at all. They are usually funded by film grants, non profit organizations, sponsor, or personal funds. Short films are generally used by filmmakers to gain experience and/or prove their talent in order to gain funding for future films from private investors, entertainment companies, or film studios.

Porcelain

Porcelain is a ceramic material made by heating materials, generally including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). The toughness, strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures.

Porcelain derives its present name from the old Italian porcellana (cowrie shell) because of its resemblance to the translucent surface of the shell. Porcelain can informally be referred to as china or fine china in some English-speaking countries, as China was the birthplace of porcelain making.Properties associated with porcelain include low permeability and elasticity; considerable strength, hardness, toughness, whiteness, translucency and resonance; and a high resistance to chemical attack and thermal shock.

Porcelain has been described as being "completely vitrified, hard, impermeable (even before glazing), white or artificially coloured, translucent (except when of considerable thickness), and resonant." However, the term porcelain lacks a universal definition and has "been applied in a very unsystematic fashion to substances of diverse kinds which have only certain surface-qualities in common".
