Updated February 14, The method relies on the measured and predictable growth of a rind that forms on the glass when first exposed to the atmosphere. Issues are that rind growth is dependent on three factors: ambient temperature, water vapor pressure, and the chemistry of the volcanic glass itself.
Recent improvements in measurement and analytical advances in water absorption promise to resolve some of the issues.
