What is an Airbrush?

The airbrush is a tiny, highly exact spray gun for applying paint. This first airbrush used a hand-operated compressor, and the inventor patented it "for the painting of watercolors and other inventive purposes". However this first device was rather crude and it took some years of further development before a practical device was developed, which was marketed by Freedom Walkup. The first modern type airbrush came along in 1893, presented by Thayer and Chandler art materials company at the World Columbian Exposition in Chicago, invented by Charles Burdick. An airbrush works by passing a stream of fast moving air thru a venturi, which creates a local decrease in pressure ( suction ) that permits paint to be pushed up from a reservoir at ordinary atmospheric pressure. The 1st step for any airbrush art project is that of preparing the surface. The method of washing will remove any loose fibers and also take care of any shrinking before placing your airbrush art design on to the material. It is advocated to employ a hand floor sander for a wall painting on a wood floor. Always recall that your purpose is to only remove any coarse areas from the surface of the wood.

The operator controls the quantity of paint employing a variable trigger which opens kind of of the nozzle employing a really fine chiseled needle. The method allows for the meshing of 2 or more colours in a seamless way, with one color slowly becoming another color.
