What is granulation?
Granulation is an intriguing characteristic of watercolor which results in the paint layer to look textured or mottled. This textured appearance is brought on by pigment particles clustering together alternatively than keeping evenly dispersed inside of the layer of watercolor paint. This clustering produces locations of darker shade (in which the pigment is dense) and regions of lighter colour (wherever the pigment is sparse.)
Watercolor paint is primarily composed of pigment (the color) and a binder these types of as gum arabic. Whether a watercolor will or will not granulate is dependent on the pigment(s) made use of in that colour. Pigments with bigger or irregularly shaped particles tend to granulate additional, when pigments with smaller, spherical, homogenous formed particles tend to granulate significantly less.
Is there any way to predict irrespective of whether granulation will take place?
Pigments are usually categorized as either “inorganic” or “organic.” Inorganic pigments normally do not comprise carbon and are largely manufactured with minerals that can be more merged or processed to build the remaining pigment merchandise. Regular earth hues designed with iron oxide (these as siennas and umbers) and colors made with metals (these as cobalt blue and cadmium purple) are some examples of inorganic pigments.
Natural and organic pigments contain carbon and are designed both from animal/plant make any difference or by working with artificial natural chemistry. Most natural pigments applied in artwork elements today are gentleman-made synthetics mainly because these are more sturdy and lightfast than animal and plant-based organic and natural pigments. Examples of artificial natural pigments are quinacridone crimson, phthalo blue, and dioxazine violet.
Normally, watercolors made with inorganic pigments are likely to granulate more than colors manufactured with natural pigments. This is because natural pigments have pretty tiny and consistently formed particles, which generates paint that produces an even application of colour. Inorganic pigments typically have much larger and a lot more irregularly formed particles. This causes the particles to clump alongside one another and settle inconsistently on the paper, which produces granulation.
In the impression over you can see a side-by-facet comparison of two MaimeriBlu watercolors on Strathmore 400 Series Watercolor paper. On the left is Cerulean Sky Blue, which is designed with an inorganic pigment, and on the ideal is Main Blue Cyan, which is manufactured with an organic pigment. The Cerulean Sky Blue is showing granulation, even though the Major Blue Cyan is not.
Having said that, the output of pigments can fluctuate from producer to maker, and realizing no matter whether a pigment is organic and natural or inorganic is only a single element in determining no matter whether a color will granulate. For case in point, there could be 2 different organizations that produce a watercolor paint from the identical inorganic pigment. One particular enterprise takes advantage of a edition of that pigment that is extra finely ground, while the other employs a version that is a lot more coarsely floor. Even although they are working with the very same pigment, the finely floor model will granulate fewer, and the coarser ground version will granulate a lot more. Therefore, categorizing inorganic pigments as granulating and natural and organic pigments as non-granulating is a beneficial beginning stage, but it is a generality alternatively than a concrete rule and you will most likely occur across colours that do not in shape in just this framework.
Before obtaining new watercolors, I recommend examining out a brand’s internet site for the two product data and shade charts. Some manufacturers include granulation data proper in their literature or packaging, and several models also have color charts that exhibit painted swatches on paper. MaimeriBlu’s on the web color chart is a terrific case in point each individual colour swatch exhibits the watercolor used to a textured watercolor paper and it is extremely easy to see which shades granulate and which do not.
Can I control granulation?
Despite the fact that we cannot entirely regulate granulation, there are means to manipulate the overall look or sum of granulation. One particular way to influence granulation is with the paper floor you are performing on. A cold press or rough watercolor paper has a extremely textured surface area with large factors and very low details. These textured surfaces stimulate granulation mainly because the pigment particles will clump and settle in the lower details of the paper texture. Hot push or combined media surfaces have a tendency to have a smoother area texture. Granulation will still take place on these papers, but the granulating pigment particles will transfer and settle randomly, and the granulation may glimpse less pronounced considering that these papers really do not have distinguished hills and valleys of texture.
The impression over demonstrates MaimeriBlu Cobalt Eco-friendly watercolor used to 4 diverse Strathmore papers. Each paper has a distinctive area texture which subtly has an effect on the appearance of the granulation.
A different way to manipulate granulation is to experiment with the quantity of watercolor paint you applied to the paper. When a significant volume of liquid is utilized to the paper, the pigment particles can conveniently transfer about and settle into the lower factors of the paper. This creates a pronounced granulation effect. When fewer liquid is applied to the paper, the pigment particles really do not have the capacity to go and circulation as a lot, so there will be significantly less visible granulation.
The image previously mentioned reveals two samples of MaimeriBlu Potter’s Pink used to the very same surface: Strathmore 500 Collection Imperial Watercolor Paper (cold push.) For the sample on the still left, I loaded up my brush and used a huge volume of the watercolor mixture to the paper. For the sample on the suitable, I used a lot less of my paint mixture and applied it to the paper with a drier brush.
Finally, granulation can be manipulated by mixing hues collectively. If you combine a non-granulating shade with a granulating shade, the granulation impact will be obvious in the combination, and you can experiment with various quantities of just about every shade to get your wanted quantity of granulation.
In the graphic above, I’ve blended MaimeriBlu Potter’s Pink (which granulates) and MaimeriBlu Long-lasting Violet Blue (which does not granulate.) You can see granulation in the ensuing combination, and you can also see some separation of the two pigments inside the mixture. In the darker areas with extra granulation, the color leans in the direction of Potter’s Pink, and in the places with considerably less density of granulated pigments, to color leans towards the Long lasting Violet Blue.
Granulation is a entertaining and exclusive attribute of watercolor that I hope you will all be inspired to check out. Experimenting with the alternatives of natural and inorganic pigments, paper surfaces, and application approaches can make limitless opportunities for incorporating granulation into your artwork.
