Sculptor blowing powder off a replica of the 'Sacred Heart' panel produced for Caverne du Pont d'Arc, France. After the grinding of a limestone block, the powder produced is blown off in order to obtain the same granularity as the original panel discovered in Chauvet Cave, France. The Caverne du Pont d'Arc is a replica cave of the Chauvet Cave, Ardeche, France, which contains some of the best-preserved Palaeolithic (stone age) figurative cave paintings in the world. These paintings are thought to be around 36,000 years old.
