Experimental 'short cut' reduces from millennia to minutes the time needed to measure glass viscosity

Researchers from the Universitat Autònoma de Barcelona and the MATGAS research centre, the Universitá di Roma "La Sapienza" and the Politecnico di Milano have designed a method which indirectly measures the viscosity of glass - something that required unfeasible observation times at human scale - based on its elastic properties. The results of the research, published this week in PNAS, questions the validity of current theories of glass formation
