An artist will very rarely attempt faux granite painting any other than the common fine-grained granites.
The term granite has been used in a very indefinite sense, and in fact signified any granular stone, but it has now a more restricted meaning.
Granites commonly consist of mica, quartz, and hornblende, or feldspar, and two of these minerals are always present, being necessary to compose the rock.
Some varieties of granite contain large crystals or fragments of feldspar, quartz, or hornblende, and these are, as specimens, by far the most beautiful.
According to their predominating colors granites are known as red,gray, white, etc., and have usually the name of the countries from which they come given them in addition.
Granites are best produced using oil based paints. The final stages of using turpentine with the oil based paints is really what makes the granite look “real” and so easy to create.
The background color should consist of the most predominating color, and the rest of the spots are put in by sprinkling or striking the brush against a stick.
When the colors have started to set, but before they have dried and while still partly wet, turpentine should be sparingly sprinkled upon the work, which will cause the spots to spread and run into each other, but it must not be overdone or a mess will result.
A little fine flaked mica may be sprinkled upon the work after it is finished, also before drying has been completed; this will give more naturalness to the granite imitations;
All granite imitated by the painter, uses the same basic technique, the color of the background is the only thing that is changed. The description for painting faux grey granite is equally applicable to those of other colors.
When the grey background is dry, sprinkle the work fully with a darker colour, formed of white and black, and then in the same manner with pure white.
