Production Processes
Glass Fabrication
Decor glass specialty production begins with the manufacturing of the base glass. The float glass process remains predominant for creating uniform, high-quality sheets. Once the glass is cast, it undergoes cutting, trimming, and edge finishing to meet dimensional specifications required for decorative applications.
Surface Preparation
Before decoration, glass surfaces are cleaned to remove contaminants. Depending on the chosen decorative technique, additional steps may include masking, application of primers, or the use of protective coatings to ensure adhesion and durability of subsequent layers.
Decoration Application
Artists and technicians employ the selected technique - etching, staining, laser engraving, or digital printing - to create the desired visual effect. For methods that rely on chemical reactions, safety protocols and proper ventilation are essential. For digital or laser processes, precise calibration of equipment ensures color accuracy and pattern fidelity.
Finishing and Quality Control
After decoration, glass pieces are inspected for defects such as bubbles, scratches, or color inconsistencies. Quality control protocols may involve visual inspection, optical density measurements, and mechanical testing to confirm that the product meets industry standards and client specifications. Finished panels are then packaged to protect them during transport.
