Sand (Fig. 2)	55.68	9.83	–	–	0.43	24.53		–	9.54
Ash (Fig. 3)	45.34	9.57	0.36	1.69	4.12	1.32	0.88	11.18	7.59
Charcoal (Fig. 4)	27.70	6.00	1.19	27.75	1.41	1.48	–	17.45	13.30

Notes. The symbol O^* marks the values of individual oxides (for example, SiO₂) and the symbol ‘–’ no identification of the element in the given sample. The measuring accuracy of the EDS detector used is up to 3% of the measured value.
