When it comes to kitchen materials, "clay" is actually a very broad range of choices. There are fire-hardened clay tiles, porcelain tiles made of compressed clay and additives, ceramic tiles with glazes and a number of other choices. These options have two primary benefits. First, they come in nearly unlimited shapes and colors, which makes planning easy. And because of the firing process, these clay products are heat-resistant and make ideal kitchen surfaces.
Stone is one of the most popular heat-resistant materials to use in kitchen counter construction. Not only does it add earth tones to kitchen spaces, but it is very durable and stands up very well to both impact and intense heat. Granite is one of the best heat-resistant options, but slate, marble and several other stone options are also good choices.
Metals are also notably heat-resistant. Stainless steel is a classic kitchen option and can hold up well under heat. There are also a number of more modern choices like copper and nickel coatings have different shades but offer similar benefits for counters, appliances and sinks. But metal can discolor in the presence of heat even if it does not burn or break.
Composite materials are man-made. While you may not think of concrete as common kitchen material, concrete slabs can be made and custom dyed for your kitchen counters, and concrete tiles may be an even easier option. Concrete is cheaper than stone, but it has some similar benefits, including heat resistance.
