Ceramic is fire resistant
We use fire in our homes for cooking and heating, but it has always posed a safety risk if it propagates away from the kitchen hob or the fireplace. Surrounding these spaces with ceramic tiles is an effective way of improving safety thanks to their fire resistance.
Some floors can withstand fire… as long as it is put out immediately. But ceramic does not contain plastic and is fire resistant.
Using ceramic tiles for the splashback behind the hob or on the floor around the fireplace protects the surfaces from hot saucepans, spilled hot liquids and sparks.
