Methods of ceramic manufacture and surface treatment may be investigated in thin section, but it is suggested that a tangential (rather than vertical or horizontal) section may be most useful. Particle orientation may be used to distinguish different methods of manufacture. Elongated or platey particles (such as mica) are most strongly correlated with forming method. Comparison of particle orientations in vertical, horizontal, and tangential sections is provided. The contrast of wheel thrown and coiled or ring built vessels is most clear in tangential sections. Examples of archaeological and experimental pottery are discussed briefly.
