FAQs About Quartz & Quartz Countertops


Quartz countertops have been gaining popularity in recent years due to their durability, low maintenance, and aesthetic appeal. However, with this rise in popularity comes a rise in questions about quartz and quartz countertops. Here are some frequently asked questions about quartz and quartz countertops.

What is quartz?

Quartz is a mineral composed of silicon dioxide. It is one of the most abundant minerals on earth and is commonly found in igneous, metamorphic, and sedimentary rocks. Quartz is also used in a variety of industrial applications, such as in electronics and as an abrasive in manufacturing.

Where is quartz found?

Quartz is found all over the world in a wide variety of geological settings. It is a common mineral that occurs in many different types of rocks, including granite, sandstone, quartzite, and shale, among others.

Quartz can also be found in the form of crystals in various locations worldwide. Additionally, quartz is a component of many types of sedimentary rocks and can be found in sandstones, siltstones, and shale, among others.

What are quartz countertops made of?

Quartz countertops are made of engineered stone, which is a combination of natural quartz crystals and resin. The quartz crystals are crushed into small pieces and then combined with resin and other additives to create a solid surface material.

Are quartz countertops expensive?

Quartz countertops can be more expensive than other types of countertops, such as laminate or tile. However, they are generally less expensive than natural stone countertops, such as granite or marble. The cost of quartz countertops can vary depending on factors such as the size of the countertop, the thickness of the slab, and the complexity of the installation.

Are quartz countertops durable?

Yes, quartz countertops are highly durable. They are resistant to scratches, stains, and heat, making them an ideal choice for use in kitchens and bathrooms. However, it is important to note that quartz countertops are not completely indestructible and can be damaged by excessive force or impact.

Are quartz countertops easy to maintain?

Yes, quartz countertops are very easy to maintain. They do not require sealing, unlike natural stone countertops, and can be cleaned with soap and water or a mild household cleaner. It is important to avoid using harsh or abrasive cleaners on quartz countertops, as they can damage the surface.

Can quartz countertops be repaired if they are damaged?

In most cases, yes, quartz countertops can be repaired if they are damaged. Small scratches or chips can often be buffed out or filled in with a resin filler. However, more extensive damage may require the replacement of the entire countertop.

Can quartz countertops be customised?

Yes, quartz countertops can be customised to fit the specific needs and style preferences of the homeowner. They are available in a wide range of colours and patterns and can be cut to fit any size or shape of countertop.

Are quartz countertops environmentally friendly?

Quartz countertops are generally considered to be more environmentally friendly than natural stone countertops, as they require less energy to manufacture and do not require sealing. However, the production of the resin used in quartz countertops does have an environmental impact, and some brands of quartz countertops may contain additives that are not environmentally friendly.

What temperature can quartz countertops withstand?

Quartz countertops are highly heat-resistant, but the specific temperature that they can withstand can depend on the manufacturer and the particular composition of the quartz countertop. In general, quartz countertops can typically withstand temperatures of up to 150°C without sustaining damage or discolouration.

However, it’s important to note that extreme and sudden temperature changes can cause quartz countertops to crack or become damaged. For example, placing a hot pot or pan directly on a quartz countertop that is at room temperature could cause thermal shock and lead to cracking or damage.

To protect your quartz countertop from heat damage, it’s best to use trivets or hot pads under hot pots and pans and to avoid placing hot items directly on the surface of the countertop. If you do accidentally expose your quartz countertop to high temperatures, it’s a good idea to let it cool down gradually before exposing it to cold water or other sudden temperature changes.

Is quartz a food-safe surface?

Yes, quartz is generally considered a food-safe surface. Quartz countertops are non-porous, which means that they do not absorb liquids or bacteria, making them a hygienic choice for kitchen surfaces.

Quartz countertops are also resistant to staining, scratching, and chipping, which makes them an ideal choice for busy kitchens where spills and accidents are common.

However, it’s important to note that the overall safety of a quartz countertop can depend on the specific brand and manufacturing process. Some brands may use resins or other materials that could potentially release harmful chemicals into the air or food, particularly when exposed to high heat.

To ensure the safety of your quartz countertop, it’s important to choose a reputable brand and to follow the manufacturer’s instructions for use and care. It’s also a good idea to avoid exposing your quartz countertop to high heat or harsh chemicals that could potentially damage the surface or release harmful fumes.

How is quartz different from marble and granite?

Quartz, marble, and granite are all natural stones, but they differ in their composition, appearance, and properties.

  • Composition: 

Quartz is composed mainly of silicon dioxide, whereas marble is composed of calcium carbonate, and granite is composed of a combination of minerals including quartz, feldspar, and mica.

  • Appearance: 

Quartz has a consistent, uniform appearance with a wide range of colours and patterns available. Marble has a distinct veining pattern with a more limited range of colours. Granite has a granular, speckled appearance with a wide range of colours.

  • Properties: 

Quartz is highly durable and resistant to scratches, stains, and heat. Marble is softer and more porous than quartz, and is more prone to scratching, staining, and etching from acidic substances. Granite is highly durable and resistant to scratches, stains, and heat, but can be more porous than quartz and may require sealing.

In terms of maintenance, quartz is considered to be the most low-maintenance of the three, as it does not require sealing and is highly resistant to staining and etching. Marble and granite, on the other hand, require regular sealing to protect against stains and may require more careful cleaning and maintenance to prevent damage.

How durable is quartz?

Quartz is a highly durable material that is well-suited for use in a variety of applications. 

Quartz is one of the hardest minerals in nature, and as a result, quartz countertops are highly resistant to scratching, chipping, and cracking. In fact, quartz is often considered to be even more durable than natural stone materials like granite and marble.

Quartz is also highly resistant to staining, as it is a non-porous material that does not absorb liquids or bacteria. This makes it a hygienic choice for kitchen and bathroom surfaces.

In conclusion, quartz countertops are a popular choice for homeowners due to their durability, low maintenance, and aesthetic appeal. If you are considering installing quartz countertops in your home, get in touch with International Granite today to discuss your needs with one of our experts.
