Approximately two-meter-high wall of 516 ceramic pieces
Porcelain, rock salt, rock flour and mineral pigments

'Erosion' is an approximately two-meter-high wall of 516 unique ceramic blocks, form a color gradient running from black to white. The dark-colored blocks were fired with ground stone and coal. The latter ingredient represents the layer of soot deposited on glaciers, which is primarily produced by the burning of coal and has been a cause of glacial recession since the nineteenth century. A mixture of salt, rock flour, and pigment gives the light-hued blocks their color. The salt symbolizes the increases in ocean salinity resulting from warming-caused changes in the global cycle of evaporation, precipitation, and water circulation. Rock flour is the product of the great pressure exerted by masses of glacial ice on the scree beneath; it is what makes glacial lakes bright blue.
