The invention relates to a single-fired glass ceramic composite brick and a production method. A blank of the ceramic brick is prepared from, by weight, 10-15 parts of clay, 0-5 parts of mineralizing agents, 0-10 parts of lithium china stones, 74-85 parts of tile-polished waste, 0-1.2 parts of peptizers and 0-0.5 part of reinforcing agents. The production method comprises the steps that the blank is processed through procedures of wet ball milling and spray drying and then processed through dry pressing to prepare a ceramic green blank; 2, the ceramic green blank is coated with a ground glaze after being dried and decorated through printing to form an overglazed color blank, and then microcrystalline glass frit dry grains are coated on the overglazed color blank to form a dry grain layer; 3, methylcellulose is sprayed and fixed on the surface of the dry grain layer, then the blank is put into a roller kiln to be fired, the firing temperature is set at 1000 DEG C-1048 DEG C, the firing time is set for 65-150 minutes, and a semi-finished product is prepared; 4, the semi-finished product out of the kiln is prepared into a finished produce after being processed through strickling for thickness fixation, rough polishing, fine polishing, edging, chamfering, air drying, inspecting and sorting, color separating and grading.
