Method for marking a surface of a refractory ceramic part, known as a “surface to be marked”, said part having - a microstructure consisting of grains comprising more than 50% by mass of ZrO2, linked by a silicate binder phase, - porosity total less than 5% by volume, said method comprising irradiating said surface with a laser beam, the beam being emitted by a laser device adjusted to respect the following relation (1): a.V2 + b.F2 + c.VF + dV + e. F + f 0, in which: a = 104. D + 2.106 b = 0.5.106. D - 150.106 c = 0.5.106. D - 300.106 d = 5.103. D - 2.5.106 e = -5.103. D + 2.0.106 f = -5.109. D + 1.8.1012 V being expressed in mm / second, D being expressed in mm and F being expressed in KHz.
