3.5. Layer sequence analysis
3.5.1. Number of layers
The number of paint layers present within each flake was recorded. 71% of flakes were single layer, 21% had two layers, 6% exhibited three layers, and the remaining 1% had four or more layers (see Fig. 5). Of the 1% of flakes having four or more layers, 6 flakes had 4 layers, 2 flakes had 5 layers, 1 flake had 8 layers and 1 flake had 9 layers. It should be noted that the two flakes with eight and nine layers were both from the same garment and the eight layer sequence was present in the nine layer flake.
