Invisibly integrated within this porcelain surface is a three- or four-element induction hob, effectively turning countertop into cooktop and freeing up space without compromising function. Each cook zone has its own power level — all controlled via an app — and, when turned off, the material instantly becomes safe to touch. Cooking Surface Prime by ABK Stone is available in large-format sizes (up to 1.6 by 3.2 metres) and a range of colourways.
