Glazing and opaque painting techniques offer unique ways to bring depth and luminosity to artwork. Glazing involves applying a thin layer of transparent or semi-transparent paint over a dry layer of paint, creating a rich and luminous effect. Opaque colours, on the other hand, are non-transparent and cover the underlying layer completely. While glazing allows for a more complex interplay of colours, opaque colours are ideal for creating bold, solid blocks of colour. Opaque colours can be made translucent by adding a clear medium, and translucent paints can be made more opaque by adding opaque colours or applying additional coats. In the world of acrylic painting, both techniques have their unique strengths and can be combined to create paintings that are rich in colour and full of life.

What You'll Learn
Glazing can be used to enhance the vibrancy of colours
Glazing is a painting technique that involves applying a thin layer of transparent or semi-transparent paint over another layer of dry paint. This technique can be used to enhance the vibrancy of colours in several ways. Firstly, by using transparent or semi-transparent colours, the underlying colour is still visible, allowing the colours to blend and create new, vibrant hues. This technique can be used to create subtle shifts in colour and tone, enhancing the overall luminosity of the painting.
Additionally, glazing can be used to restore the vibrancy of colours that have become dull or chalky. For instance, when creating an aerial perspective, artists often add white to their colours, which can result in a flat, dull appearance. By applying a glaze of opaque colour, artists can bring back the vibrancy and intensity of their original colours. This technique can also be used to create depth and dimension in a painting, making the colours appear more luminous and vibrant.
The choice between opaque and translucent paints depends on the desired effect. Opaque colours tend to provide fuller coverage, as they are not transparent and do not allow light to pass through. On the other hand, translucent paints are partially see-through and can be used to create softer, more subtle effects. When using translucent paints, it is recommended to layer from lightest to darkest to ensure proper coverage.
To enhance the vibrancy of colours when glazing, it is important to consider the inherent transparency of pigments, as this will affect the final appearance. Each layer of glaze must be completely dry before applying the next, and a steady hand is required to ensure the details of the underlying layers are not obscured. Glazing can be a time-consuming process, but it adds a rich and luminous effect to the artwork.

Opaque colours can be made translucent
Glazing is a painting technique that involves applying a thin layer of transparent or semi-transparent paint over another layer of dry paint, creating a rich and luminous effect. While transparent colours are often used for glazing, opaque colours can also be glazed to enhance the colours, values, and textures of a painting, creating depth, dimension, and atmosphere.
When mixing a transparent or translucent colour with an opaque colour, the opaque colour will always be more prominent. To achieve an even mix of colours, more of the translucent colour must be used. Additionally, when mixing two transparent colours, the principle of light vs dark must be considered. For example, when mixing a dark purple and a bright red, starting with a larger portion of the red will ensure that the purple does not overpower the red pigment.
Opaque colours can also be made more translucent by mixing them with similar colours. For instance, mixing Quinacridone Crimson with Cadmium Red makes the crimson appear stronger and more opaque. A small amount of white gesso or white paint can also be added to make the paint more opaque, but this will result in a more pastel colour.
Furthermore, the ratio of pigment to filler in paint can affect its opacity. Artist-quality paints tend to have a higher pigment content, resulting in stronger and more vibrant colours. Therefore, using high-quality paints with a higher pigment concentration can also help to make opaque colours more translucent.

Matte glazes can only be translucent or opaque
Glazing is a painting technique that involves applying a thin layer of transparent or semi-transparent paint over another layer of dry paint, creating a rich and luminous effect. Glazes can have varying levels of transparency, translucency, and opacity. Clear glazes, for example, can be transparent or translucent, but not opaque.
Matte glazes, specifically, can only be translucent or opaque. When a glaze is translucent, it allows some light to pass through without providing a clear view of what's on the other side. In contrast, when a glaze is opaque, no light can pass through, and what's underneath cannot be seen.
Opaque colours, when mixed with white, can lose some of their natural intensity, resulting in colours that appear flat and less dynamic. However, they can be used to create bold, solid blocks of colour. Glazing, on the other hand, enhances the vibrancy of colours, making them appear more luminous and alive.
When using matte glazes, artists can choose between translucent and opaque options to achieve their desired effect. Translucent glazes allow the underlying colours to show through, creating a mixed colour effect. Opaque glazes, on the other hand, completely cover the underlying layer, providing a solid foundation for subsequent glazes.

Glazes can be used to create a glowing effect
Glazing is a technique that involves applying a thin layer of transparent or semi-transparent paint over another layer of dry paint, creating a rich and luminous effect. Glazing can enhance the colours, values, and textures of a painting, adding depth, dimension, and atmosphere. While opaque colours are not typically used in glazing due to their non-transparent nature, it is possible to glaze with opaque colours to restore vibrancy and beauty to the underlying paint.
When creating a glowing effect with glazes, it is important to consider the opacity and transparency of the colours used. Transparent colours can be made more opaque by adding Titanium White or other opaque colours, or by applying additional coats. Opaque colours, on the other hand, can be made translucent by adding a clear medium. When layering colours, it is generally recommended to go from light to dark, as this allows the lighter pigments to show up on top of the darker ones.
To create a glowing effect with glazes, one can use multiple transparent glazes, as demonstrated by artist Arleta Pech. By working from light to dark, one can add warmer or cooler glazes to create special areas that glow. For example, to create a warm glow, a semi-transparent Winsor orange was used, followed by a glaze of alizarin blue lake to add a reflected colour bounce. It is important to let some of the previous glaze show through, as this builds form and deepens value.
When creating a glow-in-the-dark glaze for ceramics, a photoluminescent pigment such as europium-doped strontium aluminate or zinc sulfide can be incorporated into the glaze formula. However, it is important to note that most glow-in-the-dark pigments cannot handle high temperatures, so the glaze must be fired at a lower temperature to preserve the glow. Additionally, pottery with glow-in-the-dark glaze should be stored in a dark place when not in use to maintain its glow.

Glazing allows for a complex interplay of colours
Glazing and opaque painting techniques each offer unique ways to bring depth and luminosity to your artwork. Glazing involves applying thin, transparent layers of paint over a base layer, creating a luminous effect as light passes through the glaze and reflects off the surface below. This technique allows for a complex interplay of colours, enhancing the vibrancy and luminosity of the hues.
When translucent paints are applied over another colour, they create a "mixed" colour, allowing the lower colour to show through. This property of translucent paints makes them ideal for creating a glowing effect when used in glazing. For instance, when painting a plant in soft sunlight, you can build up varying hues of transparent yellows and oranges, and then add opaque and translucent greens on top to show the form of the plant. Finally, a bright opaque blue can be added on one side, along with a subtle blue glaze to tie the look together.
Opaque colours, on the other hand, provide a solid foundation for glazing. They are effective for creating bold, solid blocks of colour and can be used to restore the vibrancy of colours that have become chalky and dull due to the addition of white. However, when used alone, opaque colours can sometimes result in a flat and less dynamic appearance.
The interplay of colours in glazing can be further enhanced by adjusting the glaze application thickness. A thicker application will result in a less transparent glaze, while a thinner application will yield a more translucent finish. Additionally, the transparency of a glaze can be reduced by adding light-blocking particles.
By understanding and combining glazing and opaque techniques, artists can create paintings that are rich in colour and full of life.
