Protecting Quartz Worktops from Heat

Quartz worktops have grown in popularity in recent years, desirable for their durability, versatility, and stunning aesthetics. When considering Quartz worktops for an upcoming renovation project, one common question that often arises is “Can I put a hot pan on quartz?”

Putting a hot pan directly onto quartz is not recommended. Sudden drastic temperature changes known as ‘thermal shock’ can cause quartz surfaces to crack or discolour and therefore heat damage in not covered within the warranty.

In this blog, we’ll explore the dos and don’ts of placing hot pans on quartz worktops. We’ll explore the science behind quartz’s heat resistance and provide helpful tips to help you maintain the beauty and integrity of your quartz surfaces for many years.

The Science Behind Quartz’s Heat Resistant Properties

Quartz worktops boast impressive heat resistance due to their composition and manufacturing process. These surfaces are typically made from a combination of natural quartz crystals and resins, which are compressed and heated to create a durable and non-porous material. The high quartz content provides inherent heat resistance, making quartz worktops capable of withstanding fairly high temperatures without sustaining damage.

However, it’s crucial to understand the limitations of this heat resistance. While quartz can tolerate temperatures up to a certain threshold (usually 120 degrees) sudden and extreme changes in temperature can still pose a risk. This is where the concept of thermal shock comes in.

Thermal shock occurs when a material experiences rapid temperature changes, causing uneven expansion or contraction within its structure. When a hot pan is placed directly onto a quartz countertop, the localised heat can create significant temperature disparities, leading to thermal shock. This phenomenon can result in cracks, fractures, or other forms of damage to the quartz surface.

Therefore, while quartz countertops exhibit heat-resistant properties, it’s essential to handle them with care to avoid exposing them to conditions that could induce thermal shock.

Tips To Protect Your Quartz Surface from Heat Damage

To keep your quartz surface looking its best and prevent potential damage from heat exposure, consider the following tips:

Use Trivets or Hot Pads

When placing hot pots, pans, or dishes onto your quartz countertop, always use trivets or hot pads as protective barriers. These accessories help distribute the heat more

evenly and prevent direct contact between the hot cookware and the quartz surface, reducing the risk of thermal shock.

Avoid Sudden Temperature Changes

Quartz countertops can withstand moderately high temperatures, but sudden changes in temperature can still cause thermal shock. To minimise the risk, avoid placing extremely hot items directly onto a cold quartz surface or vice versa. Allow hot items to cool slightly before placing them on the countertop.

Clean Up Spills Promptly

Accidental spills of hot liquids or foods can occur during cooking or meal preparation. Promptly wipe up any spills on your quartz surface with a soft cloth or sponge to prevent heat from becoming concentrated in one area, which could lead to thermal shock or other damage.

Use Cutting Boards

While quartz countertops are scratch-resistant, they can still be susceptible to damage from sharp or abrasive objects. When cutting or chopping ingredients, always use a cutting board to protect the surface from scratches.

Keep Heating Appliances Away

Avoid placing hot appliances such as electric skillets, slow cookers, or toaster ovens directly onto your quartz countertop. Instead, use them on heat-resistant mats or stands to prevent direct contact and minimise heat transfer to the quartz surface.


In conclusion, while quartz countertops are renowned for their durability, it’s essential to treat them with care to maintain their pristine appearance and structural integrity. By understanding the science behind quartz’s heat-resistant properties and implementing practical tips to protect against heat damage, homeowners can ensure that their worktops remain beautiful and functional for years to come.
