The Painter in Oil / A complete treatise on the principles and technique necessary to the painting of pictures in oil colors

by Daniel Burleigh Parkhurst

Of all your materials, it is on your paints that quality has the most vital effect. With bad paint your work is hopeless. You may get an effect that looks all right, but how long will it stand, and how much better may it not have been if your colors had been good? You can tell nothing about it. You may have luck, and your work hold; or you may not have luck, and in a month your picture is ruined. Don't trust to luck. Keep that element out as much as you can, always. But in the matter of paints, if you count on luck at all, remember that the chances are altogether against you. Don't let yourself be persuaded to indulge in experiments with colors which you have reason to think are of doubtful quality. Keep on the safe side, and use colors you are sure of, even if they do cost a little more—at first; for they are cheaper in the long-run. And even in the time of using of one tube, generally the good paint does enough more work to cover the difference of cost.

Bad Paints.—Suspect colors which are too cheap. Good work is expensive. Ability and skill and experience count in making artists' colors, and must be paid for. If you would get around the cost of first-class material you must mix it with inferior material.

The first effect you will notice in using poor colors is a certain hindrance to your facility, due to the fact that the color is weak—does not have the snap and strength in it that you expect. The paint has not a full color quality, but mixes dead and flat. This you will find particularly in the finer and lighter yellows. You need not fear much adulteration in those paints which are naturally cheap, of course. It is in those higher-priced colors, on which you must largely depend for the more sparkling qualities, that you will have most trouble.

Unevenness of working, and lack of covering or mixing power, you will find in poor paints also. They have no strength, and you must keep adding them more and more to other colors to get them to do their work. All these things are bothersome. They make you give more attention to the pigments while working than you ought to, and when all is done, your picture is weak and negative in color.

Another effect to be feared from bad colors is that your work will not stand; the colors fade or change, and the paint cracks. The former effect is from bad material, or bad combinations of them in the working, and the latter mainly from bad vehicles used in grinding them.

I have seen pictures go to pieces within a month of their painting—bad paint and bad combinations. Of course you can use good colors so that the picture will not stand. But that will be your own fault, and it is no excuse for the use of colors which you can by no possibility do good work with.

Good Paints.—The three things on which the quality of good paint depends are good pigment, good vehicles, and good preparation.

The pigments used are of mineral, chemical, and vegetable origin. The term pigment technically means the powdered substance which, when mixed with a vehicle, as oil, becomes paint. The most important pigments now used are artificial products, chiefly chemical compounds, including chemical preparations of natural mineral earths.

As a rule, the colors made from earths may be classed as all permanent; those from chemicals, permanent or not, as the case may be; and those of vegetable origin fugitive, with few exceptions. Some colors are good when used as water colors, and bad when used in oil. Further on I will speak of the fugitiveness and permanency of colors in detail. I wish here to emphasize the fact that the origin of the material of which the pigment is made has much to do with the sort of work that that pigment will do, and with the permanency of the effect which is produced; and therefore that while a paint may look like another, its working or its lasting qualities may be quite different.

The Vehicles.—The vehicles by which the pigment is made fluent and plastic are quite as important in their effects. They not only have to do with the business of drying, owing to the substances used as dryers, but they may have to do with the chemical action of one pigment on another.
