Glass tinting is a term given to any process which alters glass to reduce the passage of light or a specific band of radiation. Glass tinting may be used to reduce the glare of light, to lower the amount of heat that enters a building or car, to allow inhabitants to remain very private, or simply as an aesthetically appealing way of decorating one's windows. Glass tinting may be done either by adding a chemical to the glass during its creation, or by adding a window film either on or between glass sheets after it has been made. Glass tinting usually results in a discoloration of some sort, depending on the chemicals used in creating the tint. Common colors include yellow, blue, green, and of course, black.
