Visual quality assessment

Examination to identify design features, visible defects or imperfections within/on the glass and mechanical damage that might affect performance during use.

Visual quality assessments are performed on a wide range of glass products and, depending on the type of product, assess a variety of different process and product-specific features and includes consideration of design features.

Examples of features that would be identified and may affect glass strength include:

• Bubbles, blisters;
• Inclusions;
• Stress raising cord;
• Scratches, chips and damage;
• Forming issues, such as splits and checks;
• Component interaction, such as metal-glass contact;
• Strength reducing design features.
