This commanding Mikasa art glass bowl is defined by a dynamic sapphire blue swirl that appears to rotate within its heavy, hand-finished crystal walls. While its daytime presence is one of cool, modernist elegance, the piece harbors a sophisticated technical secret: a high-manganese chemical composition. When exposed to 365nm UV light, the sapphire depths transform into a luminous neon-green "Radiant" glow, marking it as a premier example of mid-century technical glassmaking.
The bowl is thick-walled and weighty, with deeply molded channels that catch and refract light dramatically. The blue trails are fully cased within the glass, not surface-applied, confirming true hot-worked studio production rather than pressed decorative glass. When displayed, the piece throws crisp optical shadows and highlights, a hallmark collectors look for in quality Czech crystal.
A partially intact original Mikisi Crystal paper label remains to the base (now faded, as shown), which aligns in material, construction, and design language with known Mikisi output. Mikisi Crystal is recognized for producing export-quality decorative crystal.
Attribution & Period
Regional Example: Japan/Germany (for Mikasa), circa 1970s Bearing the original maker’s label, this piece was produced during the peak of Mikasa’s high-end "Studio" era. While the form pays homage to the Bohemian centrifugal designs of the 1960s, the precision of the mold and the specific Manganese-Radiant reaction are hallmarks of the high-clarity crystal produced by Mikasa’s premier international contractors. The 365nm fluorescence serves as a chemical signature of its authentic vintage minerals
This piece works equally well as a standalone object, vide-poche, or low-profile centerpiece, and presents exceptionally in a curated modern or postwar interior.

Measurements
• Width: 6 1/2 inches
• Length: 9 1/8 inches
• Height: 1 inch
• Weight: 1.512 lbs
⸻
Condition
Very good condition. No cracks or structural damage. Minor surface wear and micro-scratches consistent with age and gentle use, visible only under close inspection. Original paper label present but fading, as documented in photographs. Please review all images carefully, including close-ups.
⸻
Placement
A sophisticated anchor for a glass-topped cocktail table or a modernist vanity. Its sapphire tones provide an architectural pop in natural light, while its UV reactivity offers a dramatic "hidden" dimension for evening display.
Attribution & Disclosure
This piece is attributed to Mikisi Crystal, Czech Republic, based on the surviving label, material quality, forming techniques, and stylistic comparison with documented examples. As with many late-20th-century Czech export pieces, exact production year and individual designer are not recorded. Attribution is made in good faith and reflects the strongest defensible identification available.
