How to choose titanium dioxide zinc white zinc titanium dioxide in oil painting?

It is well known that in oil painting toning.

Medium white pigment is used the most and the largest amount of use, white is definitely a must for any painter, but the white used in painting is not suitable, which will lead to a very unsatisfactory effect of the whole picture, so it is particularly important to be able to correctly select the suitable white pigment among the many white pigments. Among them, titanium dioxide, zinc white and zinc titanium dioxide are the three most commonly used white pigments, titanium dioxide has strong coverage power, and is mostly used in direct painting or when pale color is needed; Zinc white has transparent properties and is mostly used for glazing or when a vivid effect is required, while zinc titanium dioxide can be used at any time.

First of all, titanium dioxide is the most covering and opaque white pigment. Titanium white was first widely used by painters in the twenties of the last century, and it is also the most widely used white pigment today. Titanium white is the most opaque and whitest of all white pigments, and mixing with any other color will saturate.

Go low. Secondly, the covering ability of titanium dioxide is very strong, it can almost completely cover the base color, and even mixed with other colors, it will also make the covering ability of other colors stronger, so titanium dioxide cannot be mixed with pigments with high transparency. In addition, titanium dioxide dries relatively quickly, but it is easy to turn yellow after a long time.

Therefore, titanium dioxide is more suitable for direct painting, or when an opaque effect is required, titanium dioxide is the best choice.

Then, zinc white is a translucent, cool-toned white, while zinc titanium dioxide is a white pigment that is intermediate between titanium dioxide and zinc white. Zinc white is a slightly transparent, cooler white that can penetrate a slight base color, so it is suitable for glazing and when you want to paint a cool color effect with a sense of translucency. And due to the translucent nature, the tinting strength and coverage of zinc white are relatively weak, and the color saturation will become higher when mixed with other colors, so it is easier to control than titanium dioxide.

Zinc titanium dioxide is a hybrid color of titanium dioxide and zinc white, combining the advantages of both, not only the opacity and high coverage of titanium dioxide, but also the anti-chalking characteristics of zinc white, so it is suitable for when you need to depict bright highlights or fine tones.

Finally, if you need good coverage or want a paler color, choose titanium dioxide, and if you want bright colors or when coloring and overcoating, choose zinc white, which is the most commonly used and unmistakable white pigment.

In oil painting, titanium dioxide, zinc white, and zinc titanium dioxide should be selected according to the color of the painting you want to express. If you choose these three different whites in the oil painting, the final painting will show different results.

It can be chosen in this way, titanium dioxide has strong covering power, and is mostly used in direct painting or when you need pale color; Zinc white has transparent properties and is mostly used for glazing or when a vivid effect is required, while zinc titanium dioxide can be used at any time.

Titanium white has a strong color and can be used to show the background, or to show the pale color; Compared with titanium dioxide, zinc white is more transparent and can be used in bright places; Zinc titanium dioxide is a neutralization of the two and can be used anywhere.

First, the coverage is different.

1. Titanium dioxide has strong coverage.

2. The zinc white covering power is weak.

Second, transparency is different.

1. Titanium dioxide has low transparency.

2. The transparency of zinc white is relatively high.

Although lead white, zinc white and titanium dioxide are all white pigments, their properties are different.

The chemical composition of lead white is lead carbonate, which has better color coverage when made into oil painting. Lead white powder is often used as a base material. Lead white is a very good white pigment in the current oil painting color, the pure lead white is very stable, if the composition is not pure, it will be yellow after a long time, the lead white oil painting color dries quickly, and the color layer is strong after drying, it is a very good white in the traditional European oil painting color, and many oil painting masters have used it.

However, lead white is very toxic, and even inhaling dust containing lead white will have serious consequences, so the grinding of lead white will bring danger to people. Most of the white oil paints produced now are zinc white, titanium dioxide or zinc titanium dioxide.

The chemical composition of zinc white is zinc oxide, the scientific name of zinc oxygen powder. Zinc white powder is slightly lighter than lead white powder, whiter than lead white, does not yellow for a long time, stable, and the color layer is stronger after drying, but it eats more oil, and the covering power is not as strong as lead white, which dries slowly, and is easy to be brittle and crackable. European painters have only been using zinc white pigments since 1840.

Zinc white turns tartrazine when exposed to heat (direct sunlight) and returns to white when cooled. Zinc white is not toxic, appears cooler than lead white, and has a tendency to be blue.

The chemical composition of titanium dioxide is titanium oxide, which is an inert pigment, which is not affected by climatic conditions and has a strong covering power, and is a pigment produced in modern times. The color of pure titanium dioxide dries quickly, and it is easy to turn yellow after drying, so it is often mixed with zinc white. Zinc titanium dioxide not only reduces the brittleness of zinc dioxide, but also improves the shortcomings of titanium dioxide alone.

Titanium dioxide has the same non-toxic advantages as zinc white. Zinc titanium dioxide is currently the largest amount of white pigment in China.

Titanium dioxide: strong coverage and low transparency.

Zinc white: weak coverage and high transparency.

Choose to use according to your different needs, usually buy titanium dioxide, zinc white is enough.
