How Much Is My Old Painting Worth? Research, Appraise, and Sell

The painting in Borneo, possibly depicting a native type of wild cattle, is among thousands of artworks discovered decades ago in the remote region. But it was only using technology called uranium series analysis that researchers have finally been able to work out just when they were painted. The discovery adds to a growing body of evidence that cave painting did not emerge only in Europe, as was once thought. In , researchers dated figurative art on the Indonesian island of Sulawesi to 35, years ago, but some of the paintings examined by Aubert and his team in nearby Borneo were produced at least 5, years earlier. Aubert, an associate professor at Australia’s Griffith University, worked with a team in remote and inaccessible caves in the East Kalimantan area of Borneo to date the paintings. The team, whose research was published in the journal Nature on Wednesday, looked at multiple layers of artwork painted on top of each other.

Work by local scientists describes more recent charcoal drawings that depict domesticated animals and geometric patterns. It also mentions patches of potentially older art in a red, berry-colored paint—probably a form of iron-rich ochre —that adorns cave chamber entrances, ceilings and deep, less accessible rooms. Previous estimates put the Maros cave art at no more than 10, years old. A hand stencil design on the wall of a cave in Sulawesi, Indonesia.

Kinez Riza Dating cave paintings can prove extremely difficult. Radiocarbon dating can be destructive to the artwork and can only be used to date carbon-containing pigment—usually charcoal.

This method also gives you the age of the felled tree that made the charcoal, rather than the age of the charcoal itself.

Life timeline and Nature timeline Cueva de las Monedas Nearly caves have now been discovered in France and Spain that contain art from prehistoric times. Initially, the age of the paintings had been a contentious issue, since methods like radiocarbon dating can produce misleading results if contaminated by samples of older or newer material, [3] and caves and rocky overhangs where parietal art is found are typically littered with debris from many time periods.

But subsequent technology has made it possible to date the paintings by sampling the pigment itself and the torch marks on the walls. For instance, the reindeer depicted in the Spanish cave of Cueva de las Monedas places the drawings in the last Ice Age.

History does not record who it was, but the incredible results of that inspirational moment are all around us – in the houses we live in, the bridges we cross, the furniture we sit on. Nails have been around for a long time. As soon as man discovered that heating iron ore could form metal, the ideas for shaping it quickly followed.

Any sizeable Roman fortress would have its ‘fabrica’ or workshop where the blacksmiths would fashion the metal items needed by the army. They left behind 7 tons of nails at the fortress of Inchtuthil in Perthshire. For nail making, iron ore was heated with carbon to form a dense spongy mass of metal which was then fashioned into the shape of square rods and left to cool. The metal produced was wrought iron. After re-heating the rod in a forge, the blacksmith would cut off a nail length and hammer all four sides of the softened end to form a point.

Then the nail maker would insert the hot nail into a hole in a nail header or anvil and with four glancing blows of the hammer would form the rosehead a shallow pyramid shape. An original 7″ mm long Roman nail found in Scotland This shape of nail had the benefit of four sharp edges on the shank which cut deep into timber and the tapered shank provided friction down its full length. The wood fibres would often swell if damp and bind round the nail making an extremely strong fixing.

In Tudor times, we have evidence that the nail shape had not changed at all as can be seen by the nails found preserved in a barrel of tar on board the ‘Mary Rose’ – the Tudor flag ship of Henry VIII built in and recovered from the mud of the Solent in A replica of the hand made nails found on board the ‘Mary Rose’ Machine made nails It was not until around that the first machine for making nails appeared, but that tended really to automate much of the blacksmith’s job.

The ‘Oliver’ – a kind of work-bench, equipped with a pair of treadle operated hammers – provided a mechanism for beating the metal into various shapes but the nails were still made one at a time.

Unearth your Jewish heritage. Knowing the type of photo can still leave a large time period, but if you know the subject of the photo, your genealogical research should be able to help you narrow that. When was the subject born?

So when is it useful to perform scientific dating? If there is a question of whether a painting is years old or years old, we have reason to perform scientific dating. Carbon Carbon dates organic material. For paintings and drawings, this means that we can carbon-date canvas, wood and paper.

Authentication and Evaluation of Paintings Is the art an original one-of-a-kind painting or print or is it a reproduction? If a side is even it’s probably a reproduction. The signature and numbers are hand-written by the artist. Borrow a high power magnifying glass the kind jewelers use or a microscope and look at a color picture in a magazine. If the magnification is powerful enough, you will see microscopic colored dots in a pattern.

Next, use this same magnifying glass or microscope and focus on the image you are studying. If you see the same type of array of dots in your picture you have a machine-made reproduction. They can be on canvas or paper on board and even be embossed to duplicate the brush marks of an original painting.

Email T T he red and black paintings are primitive yet unmistakable: The prehistoric images, created in the depths of Spanish caves, have fascinated anthropologists and tourists alike, who have all marveled at what they thought were examples of the artistic prowess of early humans. These admirers were wrong, however, according to new research that concludes Neanderthals created the images, whose ages now make them the world’s first known cave art.

Some of the paintings date to at least 64, years ago, according to a paper published in the journal Science — and they are probably much older. The prior record-holder for oldest cave art is a painting of a pig at Timpuseng cave in Sulawesi, Indonesia. It was dated to a minimum age of 35, years old.

Thomography Thanks to thermoluminescence, it is possible to differentiate authentic excavated items from recently manufactured fakes with reasonable accuracy. How do you know when a work of art was painted? Unfortunately there are no affordable direct methods for dating pigments, except in some cases as we will see later. For instance, it is possible to date the wood support of a panel as well as canvas.

The three most important dating techniques which are useful for the analysis of works of art are:

A way to test how an old painting might once have looked is to hold a white piece of paper next to it. Some part of the picture would probably at some point have been white, say, a ruff on a collar.

An analysis released in the U. The surprising revelation is but the latest in a series of cases in which “lost” pieces of artwork were rediscovered through art authentication. In the case of the da Vinci painting, the authentication was based on physical evidence. Using a high-resolution multispectral camera capable of analyzing the painting on a precise level without touching it, a Canadian forensic-art expert named Peter Paul Biro was able to identify a faint fingerprint left on the canvas.

The print was then matched to one on a known da Vinci painting hanging in Vatican City. Carbon dating of the newer canvas matched the painting to da Vinci’s period, and an analysis of the style concluded the painter was left-handed, another purported da Vinci trait. Taken together, the clues built a convincing argument for the painting’s authenticity.

See the top 10 most expensive auction items. Absent compelling forensic evidence like a fingerprint, the authentication process becomes a bit murkier. In the past, pieces of art have been certified through a combination of factors, including brushstroke patterns, analysis of the artist’s signature, dating of the pigments or canvas used or even the instinctive but subjective opinion of academics who have extensively studied an artist’s portfolio.

A painting’s provenance, or its history of ownership, is also important.

One might expect that the first examples of art would be simple and crude. However the oldest cave paintings are the evidence that modern humans were astonishingly quick in developing their artistic skills. Ancient Cave Paintings Cave paintings are paintings found on cave walls and ceilings, and especially refer to those of prehistoric origin. The earliest such art in Europe dates back to the Aurignacian period, approximately 40, years ago, and is found in the El Castillo cave in Cantabria, Spain.

The exact purpose of the paleolithic cave paintings is not known. Evidence suggests that they were not merely decorations of living areas, since the caves in which they have been found do not have signs of ongoing habitation. They are also often located in areas of caves that are not easily accessible. Some theories hold that cave paintings may have been a way of communicating with others, while other theories ascribe a religious or ceremonial purpose to them.
