Golden Open Acrylic Medium 

OPEN Acrylic Gel (Gloss and Matte) has a slightly softer feel than our Regular Gel (Gloss) and the same consistency as OPEN colors. It can be used for glazes and to extend the paints while maintaining working properties of OPEN acrylics. 

OPEN Acrylic Medium (Gloss and Matte) has a lower viscosity and is used to extend paint and maintain properties when a more fluid mixture is desired to increase flow. 
OPEN Gels and Mediums are compatible with Golden Heavy Body and Fluid Acrylic colors, as well as regular acrylic gels and mediums and will increase open time while altering their consistency. 

OPEN Thinner contains no binders and is used to thin the consistency of paint mixes without altering open time, or to maintain and adjust the workability of colors on the palette without the use of water mist and moisturizing palettes.
