You can learn a lot by looking at the back of a painting. In fact, some of the most important and revealing information about a work of art is not visible from the front. But what, exactly, can you learn from the different markings, stamps, labels, and inscriptions hidden on the back of a work of art? Originally colored off-white or beige, a canvas will darken as decades pass. When checking the back of a painting, compare it with other examples to get an idea of how much yellow color has come into the canvas. Also check for a layer of patina or grime on the back surface.
How Nuclear Bomb Tests Are Helping to Identify Art Forgeries
There are different approaches for determining the authenticity of antique paintings : – verifying authenticity through a purely stylistic evaluation – verifying the authenticity of a painting by means of objective tests of the ageing of the material – verifying the authenticity of a painting with the use of scientific instrumental methods. The combined results of the stylistic, material and scientific investigations will permit the establishing of the compatibility of the painting with presumed elements or its inauthenticity.
Portrait “Anna Selbtritt”, Thanks to the laboratory’s modern equipment, a painting can be subjected to analysis using infrared reflectography , Wood’s light , a stereoscopic microscope , IR spectroscopy and other instrumental techniques. IR spectroscopic analysis permits the analysis of various materials to ascertain their compatibility with the presumed historic period: pigments, binders, glues and varnishes.
Minimal sample quantities needed.
Why Sign a Painting. Signature Styles. Adding a Date. Signature Location. Signing Tools and Mediums. Maiden Name vs. Married Name.
Two pre-bomb and 16 post-bomb artworks by 17 midth-century Scandinavian artists were 14C dated. The majority of post-bomb samples indicated a time lag of 2—5 years between the harvesting of the plants and completion of a painting, but some samples recorded lags of up to 10 years, and others produced much earlier results, potentially indicating the use of much older canvases or challenges removing contamination prior to dating.
What Can You Learn from the Back of a Painting?
Choosing the right physical technique to analyse paintings can make all the difference when it comes to ascertaining their authenticity. This is the first time it has been possible to identify a fake painting by relying on the anomalous behaviour of the concentration of the radioactive form of carbon 14C in the atmosphere after to date the canvas. They performed tests based on techniques including X-ray radiography and scanning electron microscope and energy dispersive X-Ray spectrometry. Though they demonstrated that the fibres in the canvases differed and that different pigments were used in the two paintings, they did not arrive at conclusive evidence.
This study shows that it was necessary to perform an analysis using accelerator mass spectrometry of a sample of the canvas to conclusively date the painting.
Physicists use carbon dating to confirm alleged Fernand Léger painting was definitely a form of carbon (14C) in the atmosphere after to date the canvas.
The signature may be concealed behind the work, on the back of the canvas, or the back of the mounting for a photograph. For some conceptual work, a signature comes in the form of a certificate of authenticity. Think about what kind of signature is right for your work. If you are confused, consult a contemporary art curator, professor, or historian. Most professional artists do not sign the work on the front of the art, so that the signature does not distract from the content of the work. Make and sign your art in the same medium except for prints and graphics, which are generally signed in pencil.
For example, sign a watercolor in watercolor paint, an acrylic in acrylic medium, and an oil painting in oil paint. When you sign in a different medium, you increase the chances of someone eventually questioning whether or not the art was actually done by you. Sign all of your art in more or less the same way.
Signatures should be consistent in size, coloration, location, style written or printed , and other particulars. That way, people who do not know your art will have an easier time recognizing your work. Also, signing your name in many different ways or locations eventually makes it easier for forgers to sign art and claim that it is by you.
Dating your art minimizes any guesswork as to when something was completed.
What to look for on the back of a painting — an expert guide
If there is a question of whether a painting is years old or years old, we have reason to perform scientific dating. Carbon dates organic material. For paintings and drawings, this means that we can carbon-date canvas, wood and paper.

You and your date will paint separate canvases; when placed together, your canvases will match up to create one picture. Details make the difference — like real glassware, flattering gallery lighting, and a paint-free area for purses and coats.
Radiocarbon (¹⁴ C) dating has previously been applied to modern paintings on canvas from the 20th century to identify potential modern forgeries, and dates.
Art is not just about putting pencil or brush to paper and making something beautiful. It is about unleashing your sense of expression and entering a state of creativity where you can dig out the deepest parts of your imagination, expressing your ideas freely and apply them to whatever you desire to create something wonderful.

Oil paint has been used since the 6th century AD, while acrylic paint only began to Take a look at the way the stretcher supporting the canvas is constructed.
A technique that uses radiocarbon dating to pinpoint when an artwork was created could make it easier to detect forgeries. Conservation scientists performed the new analysis on a known counterfeit painting created by the forger Robert Trotter. She adds that the approach could be particularly effective at revealing fakes created after because materials can be dated very precisely.
But recent technological advances mean only miniscule samples are required. Hendriks and colleagues used an elemental analyser, which burns a sample to convert it into carbon dioxide gas, coupled with an accelerated mass spectrometer AMS. First, they used standard non-destructive techniques to find a suitable sample they could take from an existing crack in the painting. Once they had the samples of paint and canvas they burnt them to get carbon dioxide, which was trapped and fed into the AMS to measure the ratio of carbon to carbon
