Red Seal Glazier Practice Exam

What are common defects that can be found in glass products?

1. Cracks and shattering

2. Bubbles, waves, and distortions

3. Scratches and discoloration

4. Fading and peeling

The correct answer is: Bubbles, waves, and distortions

Bubbles, waves, and distortions are indeed common defects found in glass products, particularly during the manufacturing process. These imperfections can occur due to various factors, such as improper cooling, contamination of materials, or irregularities during the melting and forming stages. Bubbles are trapped air pockets that can weaken the glass, while waves and distortions may affect optical clarity and overall aesthetics. Recognizing these defects is essential for glaziers, as they can compromise the integrity and performance of glass installations, especially in applications where clarity is crucial, like windows or display cases. Understanding the causes and implications of these defects helps ensure that glaziers choose high-quality materials and follow best practices during installation to minimize issues related to glass quality. Other options, while related to glass, represent different aspects or conditions that do not pertain directly to manufacturing defects in the same way.
