Salt Glaze
|

Sodium, usually in the form of rock salt, is introduced into the fully heated kiln and forms a clear coating on the clay, often with an orange-peel texture. Also referred to as Salt Firing Traditionally, rocksalt is thrown into the fire at the maturing temperature of the clay until an orange-peel textured clear glaze appears; contemporarily, any sodium put into a kiln at any temperature, or during a post-firing after a work has already been fired once; salt is deleterious to kiln bricks.

Serigraph
|
 |
|
|
|
A form of print making which utilizes stencils attached to porous screens that support delicate areas of the cut design. Most often issued in signed and numbered editions.Serigraphy is a color stencil printing process in which a special paint is forced through a fine screen onto the paper beneath. Areas that do not print are blocked with photo sensitive emulsion that has been exposed with high intensity arc lights. A squeegee is pulled from back to front, producing a direct transfer of the image from screen to paper. A separate stencil is required for each color and one hundred colors or more may be necessary to achieve the desired effect. A serigraph, also referred to as a screen print, differs from other graphics in that its color is made up of paint films rather than printing ink stains. This technique is extremely versatile, and can create effects similar to oil color and transparent washes, as well as gouache and pastel.

Stone Lithography
|
 |
|
|
|
A printing method that is based on the principle that oil and water do not mix. Using a greasy substance, an image is drawn or painted on to a flat stone. Next, the stone is moistened and the surface is then coated with an oil-based ink. Paper is pressed to the stone and the ink transfers the image onto the paper. The application of each color is printed separately through a careful alignment process called registration. The popularity of this process grew because thousands of replicas could be made which closely matched the color and graphic imagery of the original art.
