Four brief observations of ceramic changes at KTC
Throughout our excavations at the archaeological site KTC, I have observed probable changes in ceramic attributes (ie. measurable features of the ceramic such as design, material, thickness, colour, etc.). This observation has occurred through sieving, working at the analysis field lab and also digging up pottery sherds. Although we are still working on analyzing pottery sherds at our site, these changes are worth mentioning as they can indicate a change in the culture of the prehistoric people occupying this site.
My first observation is that the material has changed over time. While we once were observing porcelain pottery sherds in the upper excavation units, we are now beginning to observe simpler ceramics, such as earthenware, in the deeper excavation units.
Another observation is that the colour has progressively changed the deeper we go into the deposit at the site. Although this is somewhat subjective and deserves more research, it appears that the colour has been changing from a black hue to a more reddish one within the ceramics we have observed at the site. This may indicate that they were created using different methods or that they were created using a different sort of raw material.
Perhaps the most important observation is that it appears the deeper we dig in the site, the more ceramics we find with designs on them. Although we are only at 0.60 metres deep and our analysis is basic and not yet complete, this change in the frequency of decorated pieces may indicate changes in the cultural identity of the people making the pots.
The last observation is that the thickness of the pottery seems to have increased the deeper that we dig. This also deserves a bit more data and research, but if it turns out to be a reliable observation, it could indicate a change in technology for creating thinner more fragile ceramics in more recent times.
Overall, this change in pottery could end up being a significant change in culture over time and is worth taking a deeper look into with more analysis in the lab.
