AB  - Painted metal knight shields of the Order of the Elephant produced during the 
      last part of the 20th century are characterized by a striking variety in their 
      conservation state. Three different coat systems were identified and investigated 
      by Fourier transform infrared microscopy (mu-FTIR), micro-Raman spectroscopy 
      (MRS), scanning electron microscopy-Energy dispersive X-ray spectroscopy 
      (SEM-EDX) and Thermally assisted hydrolysis and methylation-gas 
      chromatography-mass Spectrometry (THM-GC-MS). Chalking of the white paint layer 
      on the first group of knight shields displayed in the window niches was found to 
      be related to the use of titanium white of the anatase type. A pristine condition 
      of the second group could be attributed to priming of the lead rich metal support 
      with a zinc potassium chromate based primer and the use of mainly stable white 
      pigments in the top coat. Severe delamination of the paint layer of the third 
      group was caused by the formation of lead corrosion products between the paint 
      layer and the metal support. The results are discussed in relation to the 
      climatic conditions as well as the historical context of contemporary paint 
      production and availability in Denmark.
