Figure 3. FTIR of fish scales before and after silicification.

Figure 3

a. Superimposed infrared spectra of the top (black) and bottom (red) parts of fish scales. b. Superimposed infrared spectrum of demineralized fish scale (black), silicified fish scale (red) and silicified fish scale after sintering (blue). All spectra were taken from the top of the fish scales. There is no difference in the infrared spectrum between the top and bottom parts of demineralized fish scale, silicified fish scale and silicified fish scale after sintering (data not shown).
