With this project, we would like to record how traditional glass-makers in India were producing reh glass, a glass obtained using a single-ingredient recipe. Reh is a silica-rich soil containing a natural mix of immature sand with high alumina concentrations and a sodic efflorescence able to produce a vitreous material when heated in a glass furnace. This way of making glass is unique and certainly has a very ancient origin based on the compositions of early and later glass that remained fairly similar over time. The study of ancient glass production in India is impaired by the lack of archaeological traces of this craft.
