Gatorfoam

== Description ==
[3A Composites, formerly owned by International Paper Co.] A registered trademark for a laminated foamboard used for graphic arts. GatorFoam® is made from a rigid, extruded polystyrene foam core laminated between two facing papers consisting of wood fiber impregnated with resin. The strong, flat panels are water-resistant and dimensionally stable. Direct sunlight will cause bleaching and degradation of any unprotected foam. GatorFoam® is not made as an archival product and may emit acidic vapors. The rigid board has very good dent and scratch resistance.

Gauze

== Description ==
A thin, loosely woven fabric with a self-finished edge. Gauze fabric is thought to have originated in the mid-16th century in Gaza, Palestine. It is typically made from cotton, wool, silk, or synthetic fibers with a loose, open weave. Cotton gauze is often used for surgical dressings and cheesecloth. The term gauze has also been applied to any open weave material such as a sheet of wire screening or plastic mesh. 
See also leno weave.

Gel

== Description ==
A semirigid colloidal dispersion that resembles JELL-O. A gel is a highly viscous solution of solid particles dispersed in a liquid. Gels may be form by cooling a solution to the point it forms tiny crystalline matrices that trap the solvent molecules. Gels are usually transparent, have low strengths and need external support. Examples of materials that form gels are: gelatin, jelly, starch, agar, pectin, polyacrylamides, and vinyl plastisols.

Gel medium

== Description ==
A gelatinous, unpigmented medium added to oil and watercolor paints to produce more transparent colors. Megilp, a mixture of linseed oil and mastic resin, was used during the 18th and 19th centuries then abandoned. In more recent years, synthetic gel media have become available that have good handling properties and do not yellow with age. However, gel media mixed with oil paints are still likely to produce weak under-pigmented films that are susceptible to cracking (Mayer 1969).
== Synonyms and Related Terms ==
megilp; medium de gel (Port.)

Gel paint

== Description ==
A thixotropic paint formulation that has a gel consistency when undisturbed, but flows readily when brushed or stirred. Once placed on the wall, the paint again becomes stiff without running or dripping. Gel paint is prepared by adding a small amount of a polyamide resin to an alkyd resin paint or by adding hydroxypropyl cellulose to a latex paint.

Gelatin

== Description ==
A mixture of proteins prepared by hydrolyzing, via boiling, collagen obtained from skin, ligaments, and tendons. Gelatin is composed of amino acids in the following proportions: glycine (25.5%), proline (18.0%), hydroxyproline (14.1%), glutamic acid (11.4%), alanine (8.7%) along with small amounts of arginine, leucine, and aspartic acid. Gelatin is approved as a food product and is easily digestible. Its production differs from that of animal glue in that raw materials are selected, cleaned, and treated with special care so that the product is cleaner and purer than glue. Gelatin is strongly hydrophilic. In cold water, dried gelatin can absorb up to ten times its weight of water, forming a viscous mass. Adding alum to gelatin produces a harder gel. Potassium chrome alum and formaldehyde (formogelatin) also harden gelatin and make it insoluble. Gelatin is used for photographic film emulsions, sizing, adhesives, inks, encapsulation, and food.
== Synonyms and Related Terms ==
gelatine; glue; Gelfoam; Puragel
