Even though quartzite is a durable and heat-resistant material, it can still be damaged by certain factors, including:

1. Scratches - Quartzite countertops can scratch easily, especially when exposed to abrasive materials or sharp objects.

2. Stains - Liquids such as wine, juice, and oil can leave stains on the surface of the countertops if not wiped up immediately.

3. Heavy impact - Dropping heavy objects or banging utensils on the surface can cause cracks, chips or damages.

4. High heat - Direct heat from hot pots or pans can cause thermal shock and damage the material.

5. Harsh chemicals - Certain cleaning agents like bleach, ammonia and acidic cleaners can discolour or etch?the surface of the countertop.

Therefore, its important to treat quartzite with care and avoid exposing it to extreme heat or scratching agents.
