Description
Glass drying photography captures the phenomenon of water memory — the dried mineral deposits and surfactant residues left by evaporating water preserving a permanent record of the liquid water’s previous position and flow direction on the glass surface. This image was made of a large plate glass window in the minutes after a heavy summer shower, the glass half-dried, the retreating water front visible as a sharply defined boundary between the still-wet region (appearing as a deep blue-grey in reflection) and the drying region where calcium and magnesium salts are beginning to crystallise from the evaporating water film. Shot with a 100mm macro at 1:1 reproduction against a dark background that emphasises the glass surface reflections, the image shows the full hierarchy of water movement traces — the broad flow patterns of the initial rain, the capillary retreat patterns of the drying front, and the mineral deposit lines left by the final water film edges.
