Ultra-clear glass, a high-transmission, low-iron specialty glass, defines the standard of "purity" and "clarity" in high-end architecture and design.
Core Technology: Precision Control of Iron Content
Its key technology lies in the extreme reduction of iron oxide (Fe₂O₃) content to below 0.015% (compared to about 0.1% in standard float glass). This minimizes absorption in the visible light spectrum, achieving exceptional light transmittance and a neutral hue.
Key Performance Advantages
Superior Clarity & Visual Enhancement: Visible light transmittance exceeds 91.5%, offering virtually colorless, distortion-free views and daylighting.
True Color Representation: Its low solar absorption and minimal color shift ensure the authentic display of artifacts in museum showcases and merchandise in retail windows.
Enhanced Strength Potential: Lower iron content contributes to a reduced spontaneous breakage rate after tempering compared to ordinary glass.
Minimized Green Edge Effect: The glass edges show almost no green tint, ideal for frameless or minimal-framing applications.
High-End Applications
Architectural Facades & Skylights: Creates the "invisible glass" aesthetic for offices, airports, and luxury retail.
Museum & Display Showcases: The global standard for presenting artifacts without visual interference.
Premium Furniture & Interiors: Used in minimalist partitions, tabletops, and shelves.
Base Substrate for Advanced Products: The ideal base for anti-reflective glass, ultra-clear photovoltaic cover glass, and display glass.
Standards & Trends
It is governed by standards like GB/T 20314 in China. Future trends involve integration with other technologies, such as serving as a substrate for ultra-clear Low-E or laminated glass, and enabling large-format or curved applications for iconic structures.
In summary, ultra-clear glass redefines purity, evolving from a functional material into a key aesthetic element that enables pure design visions and enhances visual experience.
