Construction project or renovation buyers who choose colored glazed glass often encounter issues such as discoloration, glaze peeling, and poor pattern clarity after exposure to sunlight and rain, severely affecting the long-term aesthetic appeal.
Color-glazed glass relies on the quality of the glaze and the sintering process; premium products use inorganic glazes fired at temperatures exceeding 700°C, seamlessly integrating with the glass itself.
Key procurement controls: First, test adhesion—gently scrape the glaze surface with a blade to ensure no flaking occurs. Second, review the weathering resistance report to confirm the product remains colorfast under temperatures ranging from -40°C to 80°C. Third, verify pattern accuracy, ensuring that screen-printing errors are within ±0.5mm.
For outdoor curtain walls, choose the fully glazed model for superior waterproofing; for indoor decoration, the semi-glazed version is available to help reduce weight. Before bulk purchasing, acid- and alkali-resistant tests are required to ensure suitability for various application scenarios.
