Vintage KIG Indonesia Glass Bowl – Ribbed Design with Manganese Glow – Circa 1980s–1990s

This sturdy, clear glass bowl by KIG Indonesia features a classic ribbed exterior with vertical fluting that catches and refracts light beautifully. The bowl’s thick walls and scalloped rim add both elegance and durability, making it suitable for serving, display, or collecting.

What sets this piece apart is its manganese content—an additive used in glassmaking that causes the bowl to fluoresce under UV light. This subtle scientific trait adds collector appeal, especially among enthusiasts of uranium and manganese glassware. The manganese also contributes to the faint greenish tint visible in natural light.
