Scratch Resistance and Durability Differences Between Glass Types

When choosing a glass table top or protective surface, it’s crucial to understand how different types of glass perform in terms of scratch resistance and durability. Factors such as thickness, composition, and treatment method affect how well the glass withstands daily wear and accidental impacts.

1. Clear Glass

Standard clear glass is commonly used in furniture and offers a clean, affordable option. However, it is softer than treated alternatives.

Scratch resistance: Moderate – prone to fine scratches from metal objects or abrasive cleaners.
Durability: Lower than tempered or laminated glass; may shatter into large, sharp pieces if broken.

For standard clear glass safety guidance, refer to the Glass and Glazing Federation.

2. Low-Iron Glass (Ultra Clear)

Low-iron glass removes most of the green tint found in standard clear glass. Its chemical composition is similar to clear glass, so durability is comparable unless additionally treated.

Scratch resistance: Slightly better than standard clear if polished carefully.
Durability: Similar to clear glass; can be tempered or laminated for higher impact resistance.

3. Tinted Glass

Tinted glass includes grey, bronze, or black shades. It is chemically similar to clear glass, but certain dark pigments can slightly improve scratch resistance.

Scratch resistance: Moderate – pigment may hide minor surface scratches better than clear glass.
Durability: Comparable to clear glass; tempered or laminated variants offer higher resistance to breakage.

UK standards for safe glass are outlined by the Glass and Glazing Federation.

4. Frosted / Satin Glass

Frosted glass has a matte, acid-etched, or sandblasted surface. The roughened surface is more prone to superficial scratches but less obvious due to the matte finish.

Scratch resistance: Surface scratches are possible but usually less visible.
Durability: Similar to clear glass; tempered frosted glass provides maximum safety.

5. Tempered vs Laminated Glass

For any type of glass, tempering and lamination greatly enhance scratch resistance and durability:

Tempered glass: Heat-treated to increase strength 4–5 times over standard glass; breaks into small blunt fragments instead of sharp shards.
Laminated glass: Two or more layers bonded with an interlayer; holds together if broken and resists impact better.
