Glass is basically silica sand that has been melted and allowed to cool. An amorphous solid doesn’t have a near-perfect pattern, or even groups of patterns like a polycrystal has.

Glasshardness

On the Mohs scale, which measures the hardness of minerals, quartz ranks at 7, while typical glass ranks around 5.5. This significant difference means that quartz is hard enough to easily scratch glass. Materials with a hardness greater than or equal to 6 can scratch glass surfaces, making quartz one of the common substances capable of causing damage to glass.

Is glass harder than steelreddit

To scratch glass, you’ll need something harder than copper, made of steel or titanium, and a little bit of a sharp edge. If there’s a smooth but hard surface against the flat surface of glass, then it’s unlikely to scratch it.

Typical glass uses quartz, so anything the same or greater hardness will potentially scratch it. That said, quartz is a strong, hard material with a hardness rating of 7 but glass only comes in at 5.5 because of the arrangement of its atoms.

Glasshardness Mohs

It might surprise you to know that any material that is a “transparent amorphous solid” can be called a glass. What that means in familiar terms is that glass is not a liquid, as some have claimed. It also doesn’t have a fixed crystal structure like quartz, rubies, or even metals do.

Anything sharp and of sufficient hardness will scratch glass. This makes it difficult to protect against because almost anything in a vandal’s home can get used for tagging or scratching.

About 90% of the glass that’s manufactured is soda-lime glass. Boron and other materials are often added to glass to make it useful in different situations. Boron, for example, makes glass harder (and therefore harder to scratch).
