Aerographer

The aerographer is a method of Peinture which is based on the same principle as that of the Pistolet to painting used by the carriage-builders.

In fact the aerographer ( airbrush in English) is a gun with miniature painting whose size is that of a pen (more or less large according to the uses). The principal interest is to be able to paint or color any support using an infinity of medium (paintings, Pigment S, etc) without contact with the support. This characteristic is at the origin of its invention in the years 1880 with 1900. Charles L. Burdick a American painter in watercolours which sought to apply coats of paint to water the ones to the others without modifying the preceding ones deposited a Brevet in 1893 but an American patent of 1888 described the same apparatus.

The aerographer functions thanks to two elements:

the compressed air : The source can be a compressing or a bomb of Compressed air (disadvised) the air of course being filtered and being controlled in order to provide a homogeneous pressure.

the medium : The medium is the term used to indicate the pulverized product (painting, Huile, acrylic, Encre, watercolour, pigment, etc).

Thanks to an action carried out by the user, the compressed air will vaporize the medium in a very fine way in the shape of a cone which will make it possible according to the distance to make tiny details (lower than the size of a hair), or to cover a more important surface to paint funds or degraded S for example. The distance between the aerographer and the support conditions the quantity of medium deposited making it possible to cover more or less and thus to apply important nuances to painting carried out.

One distinguishes two types of aerographers: the aerographers simple action and the aerographers doubles action. With an apparatus of the first type, it is possible to modulate only the air flow injected, with an apparatus doubles action, one can not only modulate the air flow, but also the flow of painting. One will prefer a simple action to begin or to paint linked large surfaces, on the other hand to carry out particular details, ranges or effects, the use of an aerographer doubles action is essential.
