ARTIST AND PIGMENT

COBALT VIOLET:

• The first violet pigment it was prepared by Salvètat in 1859. Is stable, but high cost and its low coloring power prevented its wider use in paints. It is not very different from the color Cobalt Green. His drawbacks include the high cost and power of weak coloration, which limits its use among painters. It was quickly replaced by the cleanest, strongest violet manganese pigment.

                                     PIGMENT IN ACRYLICS

1. What is acrylics?: 

•  Of acrylic paint allows it to mimic the very different qualities of both watercolors and oil paints. Acrylics allow artists to capture bold colors and create images that appear solid and substantial.  
•  Acrylic paint consists of pigment suspended in a binder of acrylic polymer emulsion. Water is the vehicle for the acrylic polymer emulsion.Acrylics are sold in tubes or jars. Acrylics can be applied to the support.

      2. Mixing paints:

• The paints are mixed on the palette to create new hues, tints and shades. Because acrylics dry quickly, only a small amount of paint is applied to the palette at a time. Only the necessary colors are used. 
• The paints on the palette need to be kept moist in order to remain workable. If they are allowed to dry, they will harden and will no longer be useful for painting. 
• The amount of water that is used when painting with acrylics will have a strong bearing on the consistency of the paint and its appearance on the canvas. 

      3. Sketch & Gess:

•  Acrylic gesso will essentially “lock in” the graphite so that it won’t smear or become messy when acrylic paint is added.

      4. What is acrylic gesso?:

• Acrylic gesso is a combination of acrylic paint mixed with calcium carbonate. An acrylic polymer med Gesso is often used as to prime the canvas before starting an acrylic painting, because it makes it easier for the work surface to accept the paint. 
• Gesso is a handy tool for painting with acrylics, but it is not necessary for use with any other mediums, such as watercolors, pastels, or oils.

       5. Underpainting:

•  Creating the underpainting basically involves quickly blocking in the main areas of color, as well as blocking in the dark and/or light spots.

       6. Lights & Shadows:

• Acrylics can be applied thickly or thinly, the underpainting is typically painted using fairly thinned acrylic paint. This is similar to techniques used in watercolor painting.

       7. Adding Color:

• Artists can choose to work with underpaintings in different ways. For example, some artists will make sure the entire surface is covered with paint before working on the details. 
• It is perfectly possible to bring one specific area of the painting to completion, while the rest of the painting has not even had a touch of paint.

       8. Details:

• Because acrylics dry quickly, it is easy to layer the colors over top of one another. This makes it easy to fix mistakes. Contrast this with watercolors, where it is possible to layer colors - but the translucency of watercolors means that mistakes are much more difficult to cover up in this way.

       9. Layering & Glazing:

• Most of the painting was created using a layering process, in which one layer of paint is added on top of another.
• Once the paint is dry, it is possible to use a “glazing technique” in which a watery acrylic paint is added to certain areas to help blend that area and bring depth to that area of the painting.
• In addition to water, there are also acrylic mediums that can be used to create an acrylic glaze, such as Acrylic Retarder and Glazing Liquido.

       10. Finishing the Painting:

•  The varnish will provide a protective layer over the paint, protecting the artwork against UV rays, dust, dirt, and many other unforeseen calamities. If the painting should get dusty or dirty, it can simply be gently wiped clean with a soft, wet cloth, with no worry about removing or damaging the paint. For these reasons, varnish also helps to preserve the longevity of the acrylic painting. Additionally, because varnish “seals” the painting, it also helps to bring the painting together, making all the various areas of paint appear more unified.
