Painting with gouache

×

I did a web search on a gouache picture (pronounced "gwosh" or "goo-wash") and found that several people have accessed my website over the past few years, probably numerous gouache listed on the site. There may be pictures. There is conflicting information on this subject. As a result, this article will help you better understand as a professional art educator, with over 35 years of experience in using this opaque watercolor medium.

Intentionally, the ancient Egyptians used this. The paint was first used and later this paint was trimmed by the Italians. This refers to "mud" or "water-painted paint, splatter". Body color and designer’s color can be used interchangeably. Guazzo may also be an idiom describing the 16th-century technique of applying oil over tempera paint. Nevertheless, gouache paint was used by illuminated manuscript artists and later became popular with landscape and natural artists such as Albrecht Durer, as well as some European decorators. Because opaque paint dries quickly and can be applied in a flat and even shade, nine hundred gouache was often a favorite of architectural and advertising illustrators. Therefore, the name of the paint is "Designer’s Color".

The body of the gouache paint is made up of several elements, including pigments and opacifiers. This density additive depends on the manufacturer. Some include the Blanc Peaks (French for permanent white); In this case, barium sulfate (also used as a paper filler). Other manufacturers incorporate calcium carbonate or "precipitated" (for synthetic techniques) choke, commonly known as choke. If you empty the bucket for rinsing the brush during this painting process, the concentrate may appear as sludge at the bottom of the container. Gum Arabic is a binder that all gouache paint manufacturers accept to combine their materials. In some cases, glycerin and preservatives are mixed. The main difference between transparent watercolor and opaque is the addition of chalky matter and the amount of gum arabic. The latter has a higher concentration in gouache. If gouache is applied as impasto, it is the Arabian sword that can give the dried figure a pearl patina. If you use it too thick, such as temperature, the paint will break. Usually gouache paintings have a blurry surface. This is ideal for photographic reproduction purposes and is another reason it’s so popular with illustrators.

Some sources I’ve read say that gouache only comes in tubes. It’s not like that. Here’s a set of Pelican branded fans that I got in my teens when I first started using this type of paint in the mid-1970s. Called the "cake" form, these pans have the advantage of getting interchangeable colored cakes and a built-in palette. Since gouache paint can be rewet and processed as it dries, the tube paint can be squeezed into the cake container once the cake is empty. Gouache tubes have a shelf life of 3 to 5 years, which is the point at which the tubes solidify. When this happens, break the tube and use the dried form just like the cake form. Sometimes a single edge razor blade is used to shave the required amount with a pallet. Obviously, gouache can be purchased as a liquid, but only in small black or white jars. These are probably the only two available, since they are probably the two most used colors, and with high opacity they will settle in the jar.

Some of the advantages and uses of gouache have already been addressed, but there are more . Gouache painting materials are ideal for spilled air (outdoor painting) because they can be easily transported and dried, such as transparent colors, and some artists have used gouache as a preliminary sketch for large oils. As mentioned earlier, gouache can get wet again after drying, so you can rework plein air paintings in your studio. This quality also allows you to gradually blend and blend colors on the surface of the picture. Gouache also works well on tinted paper and can also serve as an underpainting for pastels.

The transparent watercolor technique of wet, dry brush and sputtering can also be done with gouache. However, due to the opaque material, the paint does not smudge or smear as much as the transparent color when wet. Most gouache artists use white paint, but you can also use a liquid masking agent to block out areas that leave white. As you know, in painting, "glaze" is the process of painting a thin, dilute color layer onto another layer. Once again, because of the chalky properties of gouache, many believe that glazing with gouache cannot be used. However, to solve the problem of mixing the base paint with the diluted paint when the glaze is brushed. I spray the work piece with a single layer of fixative (the same material used for pencils, chalk and pastels) and dry it. Then polish the area, especially for shadows. There are two problems with this operation. First of all, the fixture should not be too thick. Otherwise, the paint placed on top will bead and will not be covered. The second should also be kept in mind and planned. Washing off a thin layer, especially in white areas, can change its color. I’ll cover this again when I talk about finishing the painting. I also satisfactorily used gouache for airbrushing, as in the paintings "Family Going Out" and "Morning Stretch".

Another great feature of gouache. There is a saying that gouache does not mix well with acrylic. This is because the paint is crushed or is considered cottage cheese. I’ve never run into this problem, but I don’t use a lot of gouache in a tube added directly with acrylic paint, only a small amount. The way I mix it works very well. However, since acrylic dries to plastic with a smooth surface, in order to paint gouache on acrylic, a thin fixing layer must be applied to bond the gouache. Can be used with ash. Paper with 140 pounds or more thick hot or soft teeth works well. I prefer to use a rag paper called a watercolor board made by a crescent moon. Another thesis that I have succeeded in is the four-ply cloth paper used in the museum installation. This paper is soaked in water and then stretched over a wooden frame made of wood. Then the soft cotton paper is spread and stapled like a canvas.

There are many issues to consider when finishing and marking the gouache painting. The most common way to approach framing gouache is to treat it the same as you would treat a transparent watercolor with a matte and frame under the glass. In the mid-1980s, this method was not used for three reasons. The gouache painting "Misty Warm December" once participated in the National Wildlife Art Collector 's Society exhibition in Minneapolis, Minnesota. The paper had a flat, flat surface shape and was under a white mat.

The second reason is that there are two unique problems encountered when shipping pictures under glass. One is the cost of transportation increases due to weight compared to the picture, not under the glass, and the other is breakage. In order to solve these problems, we looked at how to deal with acrylic. Gouache painting can be finished with acrylic varnish. However, you need to spray a few layers of fixative so that the paint does not get acrylic varnish. This removes the dull and chalky appearance of the gouache and makes the pieces look like oil. These pictures were put directly into the frame without glass. For some reason, I’ve found that photos with high gloss luster tend to sell faster than others. because of. This obviously means that the color changes slightly. So, to get used to the effect of this technique on paint, you need to practice this technique several times. When it comes to creating the illusion of water and giving it a really moist feel, the other types of paint I’ve been working on will do the same thing. White tends to wash away, so mix acrylic to get a brighter color that is different from strong white.

When displaying artwork, such as in the case of watercolor, transparent or opaque, direct sunlight irrespective of the frame’s structure. Avoid long-term exposure to fluorescent lamps. It emits low levels of UV, so if you aren’t under UV-protected glass, the radiation that eventually fades. If you have any questions, please feel free to contact me.
