The invention discloses an underglaze color rheological reaction glaze and a preparation method thereof. The underglaze color rheological reaction glaze is sintered in the temperature environment of 1350-1380 DEG C, and comprises ground glaze and cover glaze; a glaze material used by the ground glaze is composed of the following components in parts by mass: 35 to 38 parts of aluminum oxide, 42 to45 parts of silicon dioxide, 3 to 5 parts of potassium oxide, 2 to 4 parts of sodium oxide, 1 to 3 parts of calcium oxide, 1 to 4 parts of titanium oxide, 0.5 to 1 part of tin oxide and 0.2 to 0.5 part of cobalt oxide; a glaze material used by the cover glaze is composed of the following components in parts by mass: 17 to 19 parts of aluminum trioxide, 58 to 60 parts of silicon dioxide, 4 to 6 parts of potassium oxide, 3 to 5 parts of sodium oxide, 1 to 3 parts of calcium oxide, 0.5 to 1 part of titanium oxide, 0.1 to 0.2 part of ferric oxide and 0.2 to 0.5 part of chromium oxide.
