Two-stage drying
Technical paper 35: Moisture measurement in the historic environment, published by Historic Environment Scotland in 2021, defines two-stage drying as: ‘A well-established theory of how materials dry. Stage 1 is characterised by a level of moisture at the surface of evaporation that is near saturation, as moisture flows through from greater depths. Stage 2 occurs when there is no longer a sufficient level of water to maintain high rates of evaporation. It is characterised by a decrease in liquid water transport and an increase in vapour diffusion, resulting in slower rates of drying relative to Stage 1.’
