The present invention relates to a method for producing a red brick which comprises: a brick molding step (S100) which puts clay into a molding frame and makes a predetermined sized molded product; a drying step (S200) which naturally dries the molded product; a stiffener spraying step (S300) which sprays the external surface of the dried molded product with a liquid stiffener which uses sodium silicate and sodium triphosphate as base materials; a sintering step (S400) which puts the molded product in which the stiffener is sprayed on the outer surface into a furnace and sinters at 1000-1200°C; and a cooling step (S500) which takes out the molded product which is sintered at the sintering step (S400) from the furnace and cools down to room temperature in order to be made into a finished product. The method for producing red brick manufactures the red bricks with enhanced rigidity and high concentration by having such formations.
