Encaustic Painting

from The Artist's Handbook by Ralph Mayer

Encaustic is a beeswax based paint that is kept molten on a heated palette. It is applied to a surface and reheated to fuse the paint into a uniform enamel-like finish. The word encaustic comes from Greek and means to burn in, which refers to the process of fusing the paint.

Encaustic has a long history, but it is as versatile as any 20th century medium. It can be polished to a high gloss, it can be modeled, sculpted, textured, and combined with collage materials. It cools immediately, so that there is no drying time, yet it can always be reworked.

The durability of encaustic is due to the fact that beeswax is impervious to moisture. Because of this it will not deteriorate, it will not yellow, and it will not darken. Encaustic paintings do not have to be varnished or protected by glass.

Encaustic paint has no toxic fumes, nor does it require the use of solvents. As a result, a number of health hazards are reduced or eliminated.

The History of Encaustic

Encaustic painting was practiced by Greek artists as far back as the 5th century B. C. Most of our knowledge of this early use comes from the Roman historian Pliny, who wrote in the 1st century A. D.. Pliny seems to have had very little direct knowledge about studio methods, so his account of techniques and materials is sketchy. According to Pliny, encaustic was used in a variety of applications: the painting of portraits and scenes of mythology on panels, the coloring of marble and terra cotta, and work on ivory (probably the tinting of incised lines).

Wax is an excellent preservative of materials. It was from this use that the art of encaustic painting developed. The Greeks applied coatings of wax and resin to weatherproof their ships. Pigmenting the wax gave rise to the decorating of warships. Mention is even made by Homer of the painted ships of the Greek warriors who fought at Troy. The use of a rudimentary encaustic was therefore an ancient practice by the 5th century B. C.. It is possible that at about that time the crude paint applied with tar brushes to the ships was refined for the art of painting on panels. Pliny mentions two artists who had in fact started out as ship painters.

The use of encaustic on panels rivaled the use of tempera, in what are the earliest known portable easel paintings. Tempera was a faster, cheaper process. Encaustic was a slow, difficult technique, but the paint could be built up in relief, and the wax gave a rich optical effect to the pigment. These characteristics made the finished work startlingly life-like. Moreover, encaustic had far greater durability than tempera, which was vulnerable to moisture. Pliny refers to encaustic paintings several hundred years old in the possession of Roman aristocrats of his own time.

The nature of encaustic to both preserve and color gave it wide use on the stone work of both architecture and statuary. The white marble we see today in the monuments of Greek antiquity was once colored, probably delicately tinted like the figures on the Alexander sarcophagus in Istanbul. Pliny says that when the sculptor Praxiteles was asked which of his pieces he favored, he answered those "to which [the painter] Nicias had set his hand." Decorative terra cotta work on interiors was also painted with encaustic, a practice that was a forerunner to mosaic trim.

Perhaps the best known of all encaustic work are the Fayum funeral portraits painted in the 1st and 2nd centuries A.D. by Greek painters in Egypt. A significant Greek population had settled in Egypt following its conquest by Alexander, eventually adopting the customs of the Egyptians. This included mummifying their dead. A portrait of the deceased, painted either in the prime of life or after death, was placed over the person's mummy as a memorial. Many of these pieces have survived to our own time, and their color has remained as fresh as any recently completed work.

In the great period of economic instability that followed the decline of the Roman empire, encaustic fell into disuse. Some work, particularly the painting of icons, was carried on as late as the 12th century, but for the most part it became a lost art. The process was cumbersome and painstaking, and the cost of producing it was high. It was replaced by tempera, which was cheaper, faster, and easier to work. In the 18th century the idea of encaustic painting was revived, initially by amateurs as a novelty to rediscover the techniques of the ancient painters. It was further explored in the 19th century, to solve the problem of dampness faced by mural painters in northern climates. The success of these efforts was limited, and encaustic remained an obscure art form.

In the 20th century, the availability of portable electric heating implements and the variety of tools has made encaustic a far less formidable technique. This factor has created a resurgence of encaustic painting, and it is once again taking its place as a major artists' medium. "Its effects, its visual and physical properties, and its range of textural and color possibilities make it eminently suitable for use in several different contemporary styles of painting that are not adequately served by our traditional oil-painting process."

HOW TO CARE FOR
ENCAUSTIC ART

“Will it melt?” The wax surface cures or hardens about two weeks after completion, and it would take extreme heat to melt a painting after this curing process. (Wax melts at about 150 degrees.) However, care should be taken to avoid placing the encaustic artwork in a hot car or in direct sunlight. In cold weather, encaustics should not be subjected to temperatures below 40 degrees.

Great care should be taken to not scratch or scrape the surface. It should be cleaned by very gently dusting the surface with a soft cloth in a top to bottom motion on the painting.
