Abrasive - A material used to sandcarve into a substrate.  Popular abrasives are Aluminum Oxide and Silicon Carbide.  For standard sandcarving 150 grit is recommended.  For photo etching 220 grit is recommended.

Artwork Setup - Each piece of artwork is placed in a box with a 1/4" boarder on each side.  The boxes are then repeated to fill an entire page.  Standard target page sizes at Rayzist are 13.5" x 13.5", and 13.5" x 42".

Exposing -  The process by which photo resist film is cured (hardened).  When used with a film tool, the unexposed images can be developed or "washed out."

Film Acetate - kodolith film positive/negative

Film Positive - kodolith film positive/negative; may also be used as a generic term for "film tool"

Film Tool -  UV Vellum, Laser Film, or a Film Acetate.  An opaque black image is printed or developed onto the film tool which is in turn used to transfer the image to a photo resist using an exposure process.

Flop - When an images in printed in reverse on a film tool to allow blasting on the back side of glass.

Laser Film - A semi-transparent film product that like vellum can be used with either a laser printer or copier.  When used in conjunction with 3 mil SR2000™ photo resist film, very fine detail can be achieved.

Sandcarving - Sandcarving is a method of decorating or personalizing glass, crystal, marble, stone, and other materials.  The process is a form of etching or engraving.

UV Vellum - A semi-transparent paper product that allows ultraviolet light to pass.  Can be imaged with a laser printer or copier. Used to transfer images to photo resist using an exposure process.

Washout - The process used to develop photo resist film.  The exposed photo resist film is sprayed with warm water until the image appears.
