New method solves old mystery: Hafnium isotopes clinch origin of high-quality Roman glass

(Aarhus University) Archaeological glass contains information about the movement of goods and ancient economies, yet the understanding of critical aspects of the ancient glass industry is fragmentary. Until now, it has been challenging to scientifically determine the origin of the colourless and clear glass, which was particularly favoured by the Romans. The Romans distinguished between two types of clear glass: Alexandrian and Levantine. Now researchers have found a way to localize the furnaces of the two types.

Soil studies can be helpful for border control

(University of Illinois College of Agricultural, Consumer and Environmental Sciences) Underground tunnels have been used by warriors and smugglers for thousands of years to infiltrate battlegrounds and cross borders. A new analysis published in the Open Journal of Soil Science presents a series of medieval and modern case studies to identify the most restrictive and ideal soil and geologic conditions for tunneling.
