What Is Quartz? Engineered Worktops Explained
What is quartz, and why is it one of the most popular kitchen worktop materials in the UK? Quartz is an engineered stone — made mostly from natural quartz crystals bound with resins — that delivers a hard, non-porous, low-maintenance surface. This guide explains what quartz is, how it is made and what makes it so popular. For the full overview, see our quartz worktops guide, or browse our quartz worktops at trade rates.
What Is Quartz?
Quartz worktops are made from engineered stone: around 90–93% natural quartz crystals combined with resins and pigments, then formed into hard, dense slabs. Unlike granite, which is quarried as a solid natural stone, quartz is manufactured — which is why its colour and pattern are consistent from slab to slab.
How Is Quartz Made?
Crushed natural quartz is blended with polymer resins and colour pigments, then compacted under heat and pressure into slabs. The resin binds everything into a non-porous surface, while pigments allow a huge range of colours and patterns, including realistic marble looks. The result is a worktop with the beauty of stone and the consistency of an engineered product.
What Makes Quartz So Popular?
Quartz has become a go-to choice because it combines looks with practicality:
- Non-porous — resists stains and bacteria, and never needs sealing.
- Low maintenance — everyday cleaning with warm soapy water is enough.
- Consistent — predictable colour and pattern across your kitchen.
- Versatile — available in a wide range of colours, from white to black and marble effects.
Are There Any Downsides?
Quartz can be damaged by excessive heat because of its resins, so always use a trivet, and in rare cases it can crack under certain conditions. Quality also varies between brands — here is what makes some quartz look cheap and how to avoid it.

Where Are Quartz Worktops Used?
Quartz is most popular for kitchen worktops, but its non-porous, hygienic surface also makes it ideal for kitchen islands, breakfast bars, splashbacks and upstands, and bathroom vanity tops. Because the colour is consistent across slabs, quartz is especially well suited to large kitchens and open-plan spaces where several pieces need to match perfectly. It can be cut to fit almost any layout, with options for undermounted sinks and integrated drainer grooves.
What to Look for When Buying Quartz
Not all quartz is the same. Higher-quality quartz uses a greater proportion of natural quartz and better resins, which affects both durability and how realistic the finish looks. When comparing options, pay attention to the thickness (20mm or 30mm), the quality of the pattern — cheaper quartz can look flat or repetitive — and the supplier’s reputation. Buying at trade rates from a specialist means you get genuine quality without paying showroom mark-ups.

What Is Quartz? FAQs
Is quartz natural or man-made?
Quartz worktops are engineered: made mostly from natural quartz crystals bound with resins, so they are a man-made product using natural materials.
Does quartz need sealing?
No. Quartz is non-porous, so unlike natural granite it never needs sealing.
Is quartz heat resistant?
Quartz is heat resistant but not heatproof — hot pans can damage the resin, so always use a trivet.
How long do quartz worktops last?
With proper care, quartz worktops can last for decades. Because the surface is non-porous and hard-wearing, it resists everyday wear well — just avoid direct heat and abrasive cleaners to keep it looking its best for years to come.
Can quartz worktops be repaired?
Minor chips can often be repaired by a professional using colour-matched resin. For peace of mind, choosing a quality quartz and a reputable supplier from the start reduces the chance of issues.
