Surface energy, cohesive energy, surface potential, electrical properties, internal energy, measurement of infrared line displacements under stress, measurement of charge properties, fracture velocity as a function of restituted energy and use of the MIE GRUNEISEN equation, . With these elements, you'll have a description of your glass and its properties, and you'll see that knowledge of the "initial state" is essential for comparing measurements. An article on surface breakdown will shortly be published in JAP/Perspective, which you may find useful in furthering my answer. All the best. Le Gressus.

Thank you sir

From thermodynamics; glass-transition temperature, melting temperature, enthalpy of melting , density, temperature dependence of the heat capacity.

From dynamics; temperature dependence of viscosity and relaxation times.

Much useful information may be obtained from the book;
