The invention discloses a soft-light glaze for a ceramic thin sheet. The soft-light glaze is produced and manufactured by the following steps of step 1, manufacturing blank clay; step 2, manufacturinga semi-finished product of the ceramic thin sheet; step 3, manufacturing the glaze; step 4, manufacturing the finished product of the ceramic thin sheet. The soft-light glaze for the ceramic thin sheet has the advantages that the glaze is fired at high temperature and is uniformly attached to the surface of the ceramic thin sheet, so that the water absorbent rate of the ceramic thin sheet is reduced, and the comprehensive use property of the ceramic thin sheet is improved; the water absorbent rate of the ceramic thin sheet is only 0.06%; compared with the stone material, the water absorbent rate is lower; the color difference is avoided, the radiation is avoided, the construction is simple, and the cost is reduced; the cracking is always avoided, more environment-friendly effect is realized, the maintenance is simpler, and the durability and firmness are realized.
