Carbon dating cave paintings
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.
Forgers commonly use the bottom of an original broken vessel, which has no commercial value, and make a new fake vessel on top of it.And what are some of the challenges involved in dating them?Many people will be forgiven for thinking that Australia has some of the oldest rock art in the world, but the truth there is no reliable dating to show this.Cave paintings (also known as "parietal art") are painted drawings on cave walls or ceilings, mainly of prehistoric origin, dated to some 40,000 years ago (around 38,000 BCE) in Eurasia.The exact purpose of the Paleolithic cave paintings is not known.Previously it was believed that the earliest paintings were in Europe.
The earliest figurative paintings in Europe date back to the Aurignacian period, approximately 30,000 to 32,000 years ago, and are found in the Chauvet Cave in France, and in the Coliboaia Cave in Romania.
Create fake pottery that will pass the thermoluminescence test One way to pass a fake through a TL test is to expose the newly-made pottery to a high dose of artificial radiation sources, thus fooling the measurement instruments.
However, producing fakes with this method calls for expertise on the subject, as well as expensive instruments.
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: Thermoluminescence (TL), Dendrochronology (DC), and Carbon 14 (C15). It dates items between the years 300-10,000 BP (before present).
The World Heritage site of Chauvet Cave in southern France is famous—and a source of both wonder and controversy—for having the world’s oldest cave paintings.
