Fast - Light 10, Slow - Light 10, Very Slow - Light 10 B72 Retouching Gels are the perfect media for glazing. The choice of the gel depends on the area to be glazed. Slower evaporating solvents allow glazing over larger areas. Very Slow - Light 10 gel is ideal for covering very large areas on large scale paintings. Light 10 gels give very thin and dry glazes similar in appearance to the glazes on well-aged old master paintings.

For richer, more substantial glazes Light 10 gels can be mixed with a standard solution of Paraloid B72 and Heavy 20 gels.

Glazes can be applied very precisely. The migration of the pigment during drying is prevented by pigment particles being held in place by the liquid crystal structure of the medium. This prevents the creation of drying rings and also the change in colour caused by the migration and separation of pigment particles.

The liquid crystal structure of B72 Retouching Gels has a great advantage over the standard solution of Paraloid B72 as it allows glazes to be painted wet-in-wet, giving crisp and precise results without uncontrollable migration and mixing of paint.
