Use of solvent in the medium is optional. Typically, the lighter the oil, the longer it takes to dry. The dry time of these oils can further be affected by the color being used in the glaze, as some colors take longer than others to dry (see Williamsburg dry time chart at the end of this article for more information). Drying oils like linseed, walnut, safflower or poppy oil on the other hand, dry more slowly and can take several days or even weeks to fully set up. They are also available with a variety of consistencies from fluid mediums to thixotropic gels. These mediums allow for quickly building up many layers of color. ![]() For example, fast drying alkyds can start setting up rather quickly and typically dry to the touch overnight. Most oil-based painting mediums can be used for glazing, but each will uniquely impact dry time and the look of the glaze. They are not only for creating single pure colors, but can also neutralize a color or darken areas that are too pronounced. ![]() Glazes can also be wiped back to reveal underlying colors or worked into when wet. They can enhance a single color or be used over larger sections to unify an area or the entire piece. Glazes increase gloss and visual depth and are typically used in the upper layer of an oil painting. Gloss Glazing Liquid mixed with Phthalo Blue Green Shade Heavy Body Acrylic, then Quinacridone Magenta, and Bismuth Vanadate Yellow on top of Acrylic White Gesso, wet sandedĪn oil glaze is a thin, translucent, colored layer, consisting of medium and paint. It is good to do some testing first if new to glazing, as the order of color layering can affect the visual result. A lot of layers could result in a less vibrant or dark color. Glazing is a great way of creating luminosity, depth and dimension. Choosing naturally transparent colors are easier to use with glazes, but if only a tiny bit of color is added to the medium, a translucent glaze can also be made with a naturally opaque color. It is possible to build up a thick surface consisting of many, many layers. It is important to let each layer dry properly before applying the next layer.Īcrylics can be layered almost endlessly. Glazing Liquid has a low viscosity (thin) and short rheology (drips). We offer Glazing Liquid, available in Gloss or Satin, which has a slower drying time to ease with blending. A short rheology is something that will drip or plop when it hits the surface and long rheology is something that has a long string, like honey. Rheology is another factor that makes mediums unique. There are many attributes which differentiate one medium from another including thin and watery (low viscosity), which will dry to a very thin film or thicker, more viscous and syrupy (high viscosity), which will leave a film with more body. Fluid mediums can be brushed on and will leave very little texture behind and gels will hold on to texture. Which medium you choose would be dependent upon the type of mark making you desire. This causes the color to dry a step darker and with the case of a glaze, more transparent, than it appears when wet. One thing to bear in mind when glazing with acrylics is the wet to dry color shift, due to the milky nature of the wet acrylic, which clarifies upon drying. Gloss films have the most clarity and anything semi-gloss, satin or matte are hazy due to the matting solids added to reduce the gloss that is a characteristic of the acrylic resin. Glazing with acrylics can be much simpler and faster and the possibilities are endless! Glazing can be done with almost any acrylic medium with a little bit of paint added, as opposed to a wash, which is acrylic paint thinned with water. There are very little rules with acrylics, as opposed to oil paints, with fat over lean and the slow drying time between layers. As soon as one layer is touch dry, another can be applied on top and the number of layers need not be limited. One of the gifts and joys of glazing with acrylics is the quick drying time affords the artist the opportunity to push their artwork farther faster. They can create visual depth, brilliance and luminosity. This base layer could be a color field or imagery, as in the traditional techniques of imprimatura (toned ground) and grisaille (gray or neutral tonal underpainting). Layering several transparent colors on top of one another creates optical color mixtures which have a much different visual effect than physically mixing the same colors together. In all three media, a glaze is a translucent layer of color applied on top of a base of other colors or an underpainting. The word “glaze” can have a very slightly different meaning whether you are painting with oils, acrylics or watercolor.
