There has been a continuous trend to emphasize the artistic value of glass and utilize it as a means of artistic expression in contemporary glass art. This study examines the historical background of glass art and its development in the modern era, focusing on the works of the researcher who uses glass thread as a drawing tool. This study investigates how glass production techniques have evolved and been utilized over time. Furthermore, in modern era, these production techniques actively serve as artistic tools, crucial in expressing individual creativity and thoughts. This study explicitly highlights the use of glass stringers(or glass threads) as a drawing tool in the works of the researcher, aiming to analyze cases where lines have been utilized in the historical context of glass art. After examining cases where colored glass threads have been utilized in ancient and contemporary times, the study analyzes the influence of using glass thread in the historical context of ancient glass, focusing on specific techniques such as core forming in ancient Egypt and cane and murrine techniques in Italy (Murano). Subsequently, the study explores the experimental expression of line usage in contemporary glass art by analyzing artworks of glass artists utilizing glass for linear expressions or employing glass threads or stringers as physical drawing tools. The analysis includes a detailed examination of the work of the researcher who utilized stringers as a drawing tool, drawing insights from historical reviews and artistic production research. Through this historical exploration and artwork analysis, the study derives a new understanding of line expression in glass art, presenting intriguing discussions on the potential for material utilization and expression expansion. This research contributes a fresh perspective to techniques traditionally considered decorative in glass art, anticipating new possibilities for material use and artistic expression.
