 |  |  | Gel Medium  Also called acrylic gel medium. 
 A thick, usually transparent substance that is used to alter the consistency or appearance of acrylic paints. Depending on the type used, a gel medium can add or reduce gloss, adhere mixed media or extend the amount of paint.
 
 Gel medium is available in matte, gloss and semi-gloss and some are self-levelling (when poured, create a smooth surface without manual smoothing).
 
 When used on their own, gel medium creates a textured surface on canvas prints that dries clear, effectively enhancing brush strokes and highlighting portions of the art where the application is thicker.

 Modern acrylic "Gesso" is actually a combination of Calcium Carbonate with an acrylic polymer medium latex, a pigment and other chemicals that ensure flexibility, and ensure long archival life.
 
 It is also used as a base on sculptural work, wall paintings and wood panelling, or for priming blank canvas prior to oil painting.

The high degree of reflect creates very vibrant colors, but can obscure the image in certain lighting. |  | Glued plywood  Glued plywood is a multilayer wood material, which is sheets of peeled veneer glued together. Usually plywood is formed from an odd number of veneer sheets.
