The wax extruding technique is based on the ability of the Matt Gun to transform pellets of hard wax into wire of different shapes and thicknesses as opposed to the uniform diameter of pre-extruded wax or metal wire. The ability to control the pressure of extrusion and the wax temperature allows the jewelry maker to create organic structures.
One particularly outstanding feature of this technique is that it is possible to express large volume with a minimum of weight. Three different types of wax pellets are used for modeling with the Matt Gun: Blue, Green and Red. Each wax has been formulated to create a special effect that cannot be achieved with other techniques.
A wax pellet is inserted into the Matt Gun. After two or three minutes, the gun will have reached the normal working temperature. Using even pressure, the operator pushes the gun feed rod until the wax begins to emerge from the tip, starting the designing process.
