Abstract
An item of equipment includes at least one worktop formed of at least one substrate made of transparent monolithic glass material with a surface area of greater than 0.7 m2. The substrate exhibits a light transmission TL of greater than 10% and an opacity indicator of between 5 and 90. The substrate is predominantly or completely bare or provided with coating(s) such that the substrate, thus coated, exhibits a haze of less than 15% and/or a light transmission TL of greater than 60% and/or an opacity indicator of less than 85. The item of equipment also includes at least one heating element and at least one interface for communication with at least one element of the worktop and/or with at least one external element for wireless communication. The item of equipment is devoid of light source(s).
