Table 3 Petrographic characteristic of the samples

From: Novel method of ancient pottery analysis based on radioactive isotope ratios: a pilot study

Sample determination Volume density [g/cm3] The color of the cross-section of ceramics and clay fields Petrographic nature
Crumb or sandy sprinkles “Pseudoengob” Blackened Textural features of lytic components Textural features of empty spaces
Homogeneous with clay mass Equigranular texture Variegated texture Porphyritic texture Lack of empty spaces Chaotic texture Parallel texture
