The alumina content in the bottom of the glazes, near the ceramic body, is systematically higher than near the top of the glaze. The arrows connect pairs of data (bottom and top) for individual glazes. The effect is barely noticeable for the high-lead glazes from Grøngaard (right, no arrows), indicating no significant absorption of ceramic material into the glaze compositions
