Asuka Kase (加瀬あすか), a distinguished Japanese glass artist born in 1987, utilizes the complex Venetian murrine (millefiori) technique to create delicate floral patterns within glass. She masterfully combines traditional glassblowing with precise sandblasting and mosaic-like assembly to produce ethereal functional art, ranging from sake cups to decorative plates. 

The "Swimming Series" is a contemporary collection of functional glass art that transforms everyday vessels into immersive, miniature aquatic landscapes. By embedding handcrafted murrine—tiny glass figures like swimmers and swim ring—into highly transparent glass, Kase utilizes refraction and light to mimic the clarity of a swimming pool or the ocean. Celebrated for its whimsical storytelling and nostalgic "pocket-sized summer" aesthetic, the series turns the simple act of pouring a drink into a dynamic visual experience where the art "comes to life" through the interaction of water and light.
