Product Description
Features of High Borosilicate Hourglass
1. Premium High-Borosilicate Glass Material
Crafted from high-borosilicate glass with a composition of 12.5%–13.5% boron oxide (B₂O₃) and 78%–80% silica (SiO₂), the hourglass features:
a).Crystal Clear Transparency: Minimal ferrous ions ensure the glass is colorless, allowing vivid visibility of the flowing sand.
b).Exceptional Thermal Resistance: With a thermal expansion coefficient ~1/3 that of ordinary glass, it resists cracking from sudden temperature changes. Even if broken, it forms large cracks rather than shards, enhancing safety.
c).Optical Clarity: Low dispersion and refractive index ensure a crisp, distortion-free view of the sand flow.
2. Superior Durability & Wear Resistance
a).High Hardness: The glass withstands abrasion 4 times better than standard glass, minimizing surface damage and maintaining clarity over time.
b).Seamless & One-Piece Molding: Advanced craftsmanship eliminates visible joints, ensuring airtight sealing (no sand leakage) and structural stability for precise timing.
3. Vivid Colored Sand & Smooth Flow
a)Sparkling Sand Particles: Uniform, non-sticky grains flow seamlessly through the glass, creating a mesmerizing visual effect. The sand’s clarity and shine add an elegant touch to any space.
b)Accurate Timing: Designed for consistent sand flow, ideal for precise timing in games, meditation, or daily tasks (time intervals from 1 to 60 minutes available).
4. Versatile Design & Customization
a)Aesthetic Appeal: Available in shapes like rhombus and round, some models feature delicate surface patterns, making it a stylish desktop decor or living room accent.
b)Tailored Options: Customizable sand colors and personalized logos are offered, perfect for business gifts, home decor, or branded promotions.
5. Dual Functionality
a)Practical Timer: Reliable timekeeping for various scenarios, from productivity tracking to relaxation.
b)Decorative Statement: Blends functionality with art, transforming any space into a sophisticated, eye-catching environment.
