Convenience is the key factor in the kitchen. The most convenient kitchen worktop is moisture-, stain-, heat- and scratch-resistant. It should be easy to clean and maintain. It's also important that the worktop has low porosity, so that spills don't leave stains. Otherwise the worktop will keep you busy dancing around it instead of relaxing when at home.
Worktop's resistance to high temperatures is another very desirable feature. If you have a heat resistant worktop, you can put hot pots on it, or at least not worry if this happens accidentally. The ideal kitchen worktop is scratch-resistant, so you can bruise along it with cutlery and plates, wipe it with a harsh cloth, or slice a loaf of bread when you need it. Another desirable characteristics of a kitchen worktop is that the edges don't chip when you knock pots, pans or utensils around.
Artificial stone worktops are particularly convenient in the kitchen in all these respects. The hardest and most resistant artificial stone materials for worktops are sintered stone and engineered quartz. Porcelain and acrylic solid surface are also great. Yet, acrylic solid surface being softer scratches easily.
All types of natural stone also make wonderful kitchen worktops, but such worktops need special care. You are likely to become tired soon of watching after natural stone countertop if you install it in a high traffic kitchen zone. You will need to impregnate it regularly and wipe every spill and splash as soon as it appears.
