A technical breakthrough in archaeological dating has been achieved through the use of Titanium-48 isotopic diffusion. Published in the Journal of Archaeological Science, the new methodology measures the rate of titanium ion migration in furnace slag to determine the age of metallurgical activities. Application of this technique to sites in the Vidarbha Region has refined the chronology of early iron smelting in Central India, dating it securely to 1400 BCE.
This new date significantly alters the timeline for the development of the Iron Age in the subcontinent, showing that sophisticated smelting techniques were already established well before the peak of the Second Urbanization. The Titanium-48 method is praised for its ability to provide high-resolution dates for industrial sites where charcoal or organic remains are often too degraded for reliable carbon-14 testing. The study confirms that the Vidarbha region was one of the earliest global pioneers in high-heat metallurgical engineering.
