Optical microscopy on surface and reflected light stereomicroscopy on pottery shard.
The microscopic observation of the fragment was carried out to make a general characterization of ceramic materials. The guidelines applied for the examination of each sample was evaluated:
• The technological class (ceramic)
• The shape and size of the sample (length, width, and thickness)
• The presence of decorations (incisions, impressions, and rims)
• The potential presence of pigment
• The type of paste and its colour
• The amount of inclusions present (low, medium or high)
• The shape (rounded, sub-rounded, sub-angular and angular) and dimensions (fine to coarse) of inclusions
• The presence of iron-oxides
• The potential presence of conservation interventions (glue, gypsum, label ink and label paper)
Instrument: Nikon SMZ745T.

The Minamikata site was a large settlement site located in Okayama City that flourished primarily from the Early to Middle Yayoi period. A significant amount of wooden objects have been found in good condition, letting us reconstruct the nature of agricultural implements, architecture, and various items of daily life. In addition, animal bones and shells have also been unearthed in good condition.
