The first radiocarbon dates on rock paintings were in 1987 on charcoal pigments, in some ways the most straight forward method.

The lab is based in Miami, Florida, and is the world leader in Carbon-14 analyses since 1979.

We can date your artwork , by dating materials used for its creation such as paper, canvas, wood, metal and others, using a scientific process called Radiocarbon dating (also called carbon dating or carbon-14 dating ).

It is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14. Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science.

The major advancement that laid the groundwork for the later dating revolution was the development of accelerator mass spectrometry (AMS).

That innovation led to a drastic reduction in the amount of carbon necessary for a radiocarbon date - from a few grams to less than 1 mg of carbon.

There are two types of testing technology: detectors that record radioactivity, known as beta counters, and accelerator mass spectrometers.

For beta counters, a sample weighing at least 10 grams (0.35 ounces) is typically required.

It has forwarding offices in Australia, Brazil, China, Japan, South Korea, Taiwan, and the UK.

Beta Analytic’s radiocarbon dating fees are inclusive of δ13C measurements by Isotope Ratio Mass Spectrometry (IRMS) and calendar calibration when applicable, δ18O for carbonates, and δD (deuterium) and δ18O for water.

Most radiocarbon dates on rock paintings have been attained through three major techniques: (1) dating the carbon from black paintings with charcoal pigments; (2) dating other pigments that are also organic, and more rarely pigments that include discrete organic materials that can be removed physically; and (3) dating the carbon extracted from mineral pigmented paintings in which organic matter was added in the preparation of the paints.
