1. A glass-ceramic plate for a cooking device comprising:
a first main face configured to be in contact with liquids when the plate is in the process of being used, a second main face and an edge,
a liquid-retaining bead fastened to and in contact with said first main face, wherein said retaining bead:
surrounds at least one region of said first main face so as to form a liquid-retaining reservoir, and
comprises at least two hydrophobic sub-beads inscribed within one another and separated by at least one hydrophilic zone, a width of the at least one hydrophilic zone between two consecutive sub-beads is at least greater than 500 μm and less than a threshold value, said threshold value being defined so that, when a liquid flows in the hydrophilic zone, a variation between (a) a retention time or volume of said liquid before said liquid overflows from the hydrophilic zone, and (b) a retention time or volume of a same liquid before said same liquid overflows from a hydrophilic zone having a width greater than said value, is less than 5%.
