Talk:Vitrified tile

The article looks to be a verbatim copy from the FAQ's of vitrified tile marketing sites. It does not seem informative and meeting standards. a search of the first para "Vitrified Tiles have far superior properties compared to marble or natural granite because being a manufactured product their quality" yields websites of tile marketing companies with exact content (almost the full article). — Preceding unsigned comment added by 117.192.32.121 (talk • contribs)

The article is basically a promotion for the product. I added a disadvantages section but it needs expansion. Jojalozzo 16:28, 31 March 2012 (UTC)

My humble opinion

As someone that has been in the tile industry for over 25years, In my opinion the word "Vitrified" describes the result of fine minerals being baked to a point where the individual grains or particles melt & fuse together creating a single mass with extremely low porosity. However, whatever the "Technical Definition" I find that when the word is used by a client seeking "Vitrified Tiles" The clients are usually looking for tiles that are coloured from Face to Back with the idea that if chipped there is no underlying colours to be exposed. Therefore the expression "Vitrified Tiles" is more often used as a way to describe a particular practical advantage of a Tile. The Pro's & Con's of these tiles can be situational specific and any tile should be weighed against its intended use or environment to determine it's situational appropriateness regardless of material or composition. This is my humble opinion & I am very happy to hear yours --Wilcas (talk) 23:06, 27 May 2012 (UTC)

Vitrified as Defined in ANSI A-137.1

In the U.S. the term "vitrified" when referring to ceramic tile is a technical term with a very specific meaning. It identifies a class of tile that absorbs more than 0.5%, but not more than 3.0% of its weight in water when tested using the process described in ANSI 137.1.5.3.1.3.1 published by the American National Standards Institute. The water absorption test is just one of many tests to which ceramic tile is subject.

ANSI has defined four water absorption classes:

Class	Definition	Applications
Non-Vitreous	Water absorption of more than 7.0% by volume	Suited for non-wet applications: around fireplaces, for example. Typically intended for walls, hobby and crafts use
Semi-Vitreous	Water absorption of more than 3.0 percent, but not more than 7.0 percent	Suited for or areas that may get wet on occasion, but are unlikely to see constant or standing water: Bathroom or kitchen floors, kitchen back-splashes or countertops, for example.
Vitreous	Water absorption of more than 0.5 percent, but not more than 3.0 percent	May be used in any indoor application including shower walls and floors. Outdoors in areas that do not experience a hard freeze.
Impervious	Water absorption of 0.5 percent or less	Suitable for any application, indoors or out, including areas that experience a hard freeze in winter.

The term has no bearing on whether the tile is colored from face to back. It refers solely to the tile's water absorption characteristic. A tile that is colored front to back through the body is generally referred to as a "full-bodied" or "through-bodied" tile. Some vitreous tiles are full-bodied, but most are surface coated with glaze, and are not full- or through-bodied.
