Ingredients

soot, lamp black

Evidence

"Our findings demonstrated that black paint... was consistent with the database-matched lamp black by 82.27% hit score."

Remarks

The pigment was identified by Raman spectral data showing sp3 and sp2 hybridised amorphous carbon FWHM at D and G bands at 1384 and 1609 cm-1 (p. 3). The absence of a phosphate band at 960 cm-1 specifically confirms that the pigment is not bone black or ivory black (p. 3). The crystallite size was determined to be 24.33 nm using the ID/IG intensity ratio of 0.79 (p. 4). FWHM values for the D and G bands were 101.01 and 213.95 cm-1 respectively (Table 1, p. 5).
