Can you put a hot pan on a quartz worktop?

This question comes up constantly because quartz looks and feels like stone, and people reasonably assume it behaves like stone. It does not, and the reason is worth knowing: around 7 to 10 per cent of an engineered stone slab is polymer resin holding the ground quartz together, and that resin has a much lower temperature limit than the mineral does.

Step by step

1. Understand what quartz actually is.Ground natural quartz — typically 90 per cent or more by weight — bound in a polyester or similar resin with pigments. The mineral part is extremely hard and heat-tolerant. The resin part is a plastic.
2. Know what the failure looks like.A pale, dulled or yellowed patch the size and shape of the pan base, which does not clean off because it is the resin that has changed rather than a deposit on the surface. It is permanent.
3. Know the second failure mode.Thermal shock. A very hot object on a cold slab, particularly near an edge, a cut-out or a joint, creates a temperature difference across the material and can crack it. This is rarer than staining but far more expensive.
4. Compare granite honestly.Granite is solid mineral with no resin binder and tolerates a hot pan far better. It is still worth using a trivet, because thermal shock near a cut-out is possible in any stone and because the sealer on the surface has its own limits.
5. Compare the others.Stainless steel is indifferent to heat. Solid surface is acrylic and marks. Laminate scorches through to the core permanently. Timber scorches and the mark is sandable, which makes it the only recoverable one.
6. Put trivets where the pans land.Not in a drawer. Beside the hob, on the worktop, permanently. The realistic prevention is that reaching for a trivet has to be easier than not reaching for one.
7. Watch the places nobody thinks about.A slow cooker or an air fryer running for hours on a quartz top, an electric hob's edge, and a hot roasting tin set down straight from the oven are all the same problem with less drama attached.
8. Ask what the guarantee actually covers.Heat damage is excluded from most engineered stone warranties, which is a good indication of how the manufacturer expects the material to behave. It is worth reading before assuming the worktop is covered.

Tips

• A heat-resistant mat left permanently beside the hob is the practical answer in a busy kitchen. A trivet you have to find is a trivet you will not use.
• Some quartz manufacturers publish a maximum surface temperature — often somewhere between about 150 and 200°C. A pan base straight off a gas or induction hob is well above that.
• If a quartz top has already been marked, there is no domestic repair. A fabricator may be able to improve it by re-polishing in some cases, but the resin change is usually through the surface layer rather than on it.
• The same applies to sinks. Setting a hot pan down in a composite sink can mark it for exactly the same reason.
