The invention relates to the technical field of ceramics, and discloses a method for producing a ceramic product with an anti-counterfeiting function by using a high-temperature-resistant upconversion material, the high-temperature-resistant upconversion material is added into an underglaze color material, and the addition amount is 3-5wt% of the total weight of the underglaze color material; drawing a pattern on a ceramic body by adopting the underglaze color material; applying transparent glaze; sintering at the temperature of 1100 to 1320 DEG C; or coating the slurry A on the surface of the ceramic body; locally covering the slurry B; sintering at the temperature of 690 to 820 DEG C; the slurry A comprises lead-free glass powder and a blender; the slurry B comprises a decorative pigment, a blender and a high-temperature-resistant upconversion material; the addition amount of the high-temperature-resistant upconversion material is 1-5wt% of the total weight of the slurry B; wherein the high-temperature-resistant up-conversion material is YSZ: x mol% of Er < 3 + > and y mol% of Yb < 3 + >; 0 < x < = 6, and 0 < y < = 20. The high-temperature-resistant up-conversion material disclosed by the invention still has efficient luminescence performance after being subjected to secondary high-temperature sintering, and has a wide application prospect in the technical field of ceramic tracing and authentic identification.
