Radiocarbon dating of rock paintings
Finally, to rock art research, the identification of carbon-based organic pigments is of special interest since it opens the way for radiocarbon dating. Dating rock art is one of the major challenges faced by archaeologists, and it is absolutely necessary to place the art in a cultural context. Not without technical difficulties and strict protocols […]
How Does Plasma Oxidation Work?

New Mexico scientist builds Carbon dating machine
Carbon dating machine The contraption he built looks a little like something you might see from.. But Marvin Rowe is no nut. That machine he built, and what it’s used for, helped Rowe win the prestigious Fryxell Award for Interdisciplinary Research from the Society of American Archeology two years ago. “We call the process Low […]
Research Details For Plasma
Since 1994, the National Park Service has been running a program called the National Center for Preservation Technology and Training. This program does research on how to preserve old things like artifacts, buildings, and landscapes. It also gives out grants, teaches people, and offers training opportunities in these areas. They have spent over $10 million […]
