Abstract: A glass-ceramic plate for a cooking device includes a first main face to be in contact with liquids, a second main face and an edge, a liquid-retaining bead fastened to and in contact with the first main face, wherein the retaining bead surrounds a region of the first main face so as to form a liquid-retaining reservoir, and includes at least two hydrophobic sub-beads inscribed within one another and separated by hydrophilic zones, a width of the hydrophilic zone between two consecutive sub-beads is throughout at least greater than 500 ?m and less than a threshold value, the threshold value being defined so that, when a liquid is present in the hydrophilic zone, a variation in the retention time or volume of the liquid before overflowing, relative to a same liquid present in a hydrophilic zone, the width of which is greater than the value, is less than 5%.

Abstract: A vehicle glazing includes on its surface to be exposed to the exterior atmosphere, at least in a zone not wiped by the windscreen wipers, a mineral oxide layer of 0.1 to 20 ?m thickness, 30 to 90% of the volume of which consists of 20 to 300 nm open pores that are distributed uniformly throughout the thickness of the layer, and almost all of which are connected to one another, the internal and external surface of the layer being functionalized with a compound containing a perfluoroalkyl or alkyl functional group, then saturated with a hydrophobic oil that impregnates the functionalized porous layer and forms a film on the surface thereof, the at least one zone being located facing a detecting device such as an anti-collision/obstacle-detecting/security video camera, or similar, placed in the interior of the vehicle, in particular on the face of the glazing.
