Glass is glass

alternating improvements

Glass is glass. Manufacturers alternate improvements in shatter resistance and scratch resistance, because optimizing one makes the other worse. They often bundle other design changes into durability claims.

• 🔀 Companies improve shatter resistance one year, then scratch resistance the next, creating alternating curves.
• ⚖️ Making glass harder increases scratch resistance but also brittleness; making it softer reduces brittleness but increases scratches.
• 📱 Gorilla Glass and Apple's Ceramic Shield follow this pattern, improving one property while the other plateaus or degrades.
• 📐 Phone design elements like flat sides, bezel thickness, and display shape significantly impact shatter resistance, not just the glass itself.
