JR Lunar Base Crystal Whiskey Tumbler – Moon Texture Heavy Bottom Glass

Some glasses hold a drink.
This one holds a moon.

The base is sculpted with a cratered lunar texture, capturing the irregular surface of the moon in solid crystal. When filled with amber whiskey or warm tea, light gathers across the contours, turning the “moon” into a quiet glow of gold.

The slightly tapered waist improves grip and balance, giving the glass a natural, secure hold in the hand. Heavy, clear, and architectural, it feels less like ordinary glassware and more like a small object carved from ice or stone — designed for slow evenings, low light, and unhurried moments.

Made from potassium–barium lead-free crystal, melted at 1400°C for higher hardness and exceptional clarity.

Each piece is fire-polished at temperatures above 1100°C, then annealed twice to stabilize the structure and prevent stress fractures. This process produces a smooth, refined surface while maintaining the sharpness of every cut.

The glass is engineered to withstand temperatures up to 100°C and thermal differences of 90°C, making it suitable for both hot tea and chilled spirits without compromise.

When gently tapped, the crystal produces a clean, metallic resonance — a hallmark of dense, high-quality material.

Washing
Hand wash with warm water and mild, non-abrasive cleaners.
Drying
