Rosin Dust Storm

One of the most mysterious, magical and hazardous forms of aquatint is achieved by using rosin dust. Rosin is essentially pine tree pitch. It is ground into a fine dust and applied to a copper intaglio plate using either a rosin box or rosin bag. When using a rosin box, the plate is placed on a grid inside the box and the handle is turned over and over again to create a dust storm of rosin within the box. The result is a fine cover of rosin that is distributed evenly onto the surface of the plate. The plate is then warmed to melt the rosin which will eventually harden to create a resist. The final step is to pop the plate into an acid bath which will etch or "bite" the open areas of the plate.
