Fig. 12: Schematic representation of synergistic bio-geochemical degradation process induced by elements and microorganisms in marine environments.

a Bio-geochemical degradation process on the surface of the glaze affected by barnacle attachment. b Bio-geochemical degradation process on the surface of the glaze affected by red coral attachment. c Bio-geochemical degradation process on the surface of the glaze affected by Rhizocaulus attachment. d Bio-geochemical degradation process starting on the surface of the glaze affected by bryozoan attachment.
