Archaeology: the science dialoging with material culture through ever-improving scientific techniques

When prehistoric pottery acquires rice and millet husks on their surface while they’re being produced, their impressions are left on the surface even though husks disappear during the firing. If we can identify the date of clay vessels, we’ll be able to clarify the subsistence of the period. Therefore, potsherds are attracting attention as extremely significant evidence to study the past plant use in Japanese archaeology. The material for creating a positive model of a seed impression on the pottery surface has changed from the oil clay or plaster to silicon resin, and The presence of a husk impression on the pottery surface is currently observed using a scanning electron microscope instead of an optical microscope, thanks to ever-improving scientific technology. Unlike historical documents, which are based on the writer’s viewpoint, material culture is unbiased evidence showing people’s actual life of the past. They’re unprejudiced primary sources for historical research. What can be collected from these sources depends on the researcher’s approach. While thinking of their own approaches, students are expected to reveal human history that has not been documented in the previous studies and textbooks.

Don’t hesitate to use new methods:
Technology transfer for future studies

Archaeologists should never take the research stance that “This is enough.” Every day they’re required to develop research methods, to provide feedback onsite in the field and to seek better methods in a repeated fashion. For this reason, it’s extremely important for graduate students to tackle various technologies. In anticipation of your participation in research on archaeology, I’m ready to unsparingly and promptly transfer the knowledge and technologies I’ve acquired. Once you experience delicate work, you should be able to apply that experience to your research without hesitation whenever you wish to. You don’t have to feel the hesitation that comes from a lack of experience. The education system in relatively small classes at Hokkaido University is ideal for students majoring in archaeology. It helps to foster close relationships between teaching staff and students, enabling the detailed instruction of individual students.
