Abstract

In this study, investigated the possibility of quantitatively and qualitatively analyzing Korean ancient glasses via Raman Spectroscopy. We subjected four categories of Korean traditional glasses, namely, lead-BaO, lead, potash, and soda glasses (3, 3, 10, and 10 pieces, respectively), to this analytical technique. The results showed significant differences between the stretching and bending Raman vibration regions corresponding to these different Korean ancient glass types. Specifically, the stretching vibration regions corresponding to lead-BaO and lead glasses showed peaks at 1040 and 1000 cm-1, respectively; the stretching vibration region of normal glass appears at 1100 cm-1. The bending vibration regions corresponding to potash and soda glass showed Raman peaks at 490 and 560 cm-1, respectively. Furthermore, the Raman spectra of the lead and lead-BaO glasses showed red shifts, which depended on the amount of PbO present. Thus, our findings highlighted the possibility of quantitatively determining the amount of PbO, a major component of lead glasses, via Raman Spectroscopy.

본 연구는 한국의 고대 유리에서 납바륨유리 3점, 납유리 3점, 포타쉬유리 10점 그리고 소다유리 10점을 중심으로 라만분광분석법을 이용하여 고대 유리의 융제 분류와 납유리에서 납의 정량 분석에 대한 가능성을 분석하였다. 분석 결과, 신축 진동 영역에서 납바륨유리가 1040 cm-1, 납유리가 1000 cm-1으로 라만 피크 에너지의 차이를 보이며 포타쉬유리와 소다유리는 굽힘 진동 영역에서 Na과 K 양이온의 차이에 따라 포타쉬유리는 490 cm-1에서, 소다유리는 560 cm-1에서 라만 피크의 차이를 보인다. 이외에 납유리는 PbO 함량에 따라 라만 스펙트럼의 적색 편이가 비례하므로 이를 통하여 납유리의 주성분인 PbO의 함량을 정량적으로 분석할 수 있다. 즉, 라만분광분석법으로 납바륨, 납, 포타쉬 그리고 소다유리에 대한 분류와 납유리에서 PbO 함량을 측정할 수 있는 가능성이 확인된다.
