This amberina glass bowl was produced by Sasaki Glass Company of Japan during the mid-20th century, likely in the 1970s. Amberina glass, characterized by its distinctive red-to-amber gradient coloring, became highly popular during the Mid-Century Modern era as both functional tableware and decorative art. The clover or quatrefoil shape reflects the organic, nature-inspired design aesthetic that defined the period. Sasaki Glass was renowned for producing high-quality art glass pieces that combined traditional Japanese craftsmanship with contemporary Western design trends. These vibrant amberina pieces appeal strongly to Mid-Century Modern collectors and vintage glassware enthusiasts who appreciate the bold color palettes and sculptural forms characteristic of 1960s-1970s design. The clover shape and gradient coloring make these bowls particularly desirable as decorative accent pieces that capture the optimistic, colorful spirit of the era. Collectors of Japanese glass and MCM decorative arts actively seek Sasaki pieces for their quality, aesthetic appeal, and relatively accessible price points compared to European art glass of the same period.

The glow is focused on the rim of the bowl.
