What is Glass?

It is transparent component made from limestones, sand and soda ash. Other materials like Barium and Silica are also used to change its color or thickness.

Our dining table will be incomplete without glasses. Various kind of food storage containers are produced from it. It is also used for making windows, camera lenses and lab equipment’s.

What is Crystal?

Crystal is a kind of glass but the difference is it also contains lead oxide, potassium carbonate and silica. These components make it more durable so that it can be molded into different shapes.

These also make the crystal porous. Because of this, it can reflect the light brilliantly. Different types of companies produced crystals with varying levels of lead oxide.

Crystal doesn’t have crystalline structure in its components. “Cristallo”, an Italian term which is generally used for high end hand blown glass in Italy is the origin of the name “Crystal”.

Difference between Glass and Crystal

Both are produced in the same way, By heating in a fireplace until they molten. Then glassblower is used to blow and shape them into desired designs.

Crystal vs Glass

Though there are similarities in the making procedure of both of them, still there are so many differences between glass and crystal. In this article we are going to discuss all of them.

Difference in the appearance

Glass: Glass is generally a bit of foggy in appearance. t can have a green tint, if it is produced with iron or blue tint.

Crystal: Crystal is heavier in weight than glass as it contains lead or other materials in its composition.

Difference in thickness

Glass: Glass can be heated at higher temperatures than crystal as it contains soda-lime in its chemical composition. That’s why glass is thicker than crystals. In characteristics, it is also more fragile than crystal.

Crystal: It can be heated at lower temperatures than glass as it contains lead oxide and potassium carbonate in its composition.

It is also thinner in shape than glass. Other chemicals which are added into it, enable it to remain strong if it is in a stretched condition.

Difference in cut

Glass: Generally you will get little time to cut a glass as it hardens quickly. Temperature is needed to be increased and in that increased temperature glass is bent into shape or blown into a mold.

Differences in sound

Glass: When glass is tapped, it creates a dull chime and the sound is subtle.

Crystal: In case of crystal, it creates a bell-like ringing sound and the sound is usually longer than the sound created by tapping of glass.

Differences in refraction

Glass: Light can pass through glasses without any type of refraction. The reason behind this is glass has no extra added materials.

Crystal: Crystals can refract light more than glass because of the added lead oxide and metal content like potassium carbonate.


Glass: Glass is mostly used for food storage containers and dishwashers. Our dining table remains incomplete without glass. It is generally used for our daily usage. Glass is also used for making lab equipment.

Crystal: From the above writeup, we got to know that crystal can refract light. This characteristic of crystal makes it a suitable material for making luxurious dinner sets, bowls, ornaments, chandeliers etc. It is also known for its ringing noise which we have talked about earlier. Because of this characteristic, it is used at weddings.
