A method for manufacturing ceramic pieces with perforations comprising pressing wet powder (4) into a mold (1) from which a ceramic covering piece will be obtained. A flat body (7) that is later dried and baked is obtained with the pressing and hence, the ceramic piece is obtained. One or several perforations (8) may be made during the pressing process so that the flat powder body (7), so that the ceramic piece resulting from baking the flat powder body includes the perforation or perforations (8) that can be used for inserting or passing the elements for fastening the ceramic piece to a face. The perforations (8) are made with perforating punches (6) embedded in the pressing tamper (3) of the mold (1) and partially emerging in order to be inserted during pressing in the powder mass (4'), producing the corresponding perforations (8). The powder (4'') of each perforation is contained unpressed in the perforating punch (6) and is emptied once the pressing operation has finished. A device for making the ceramic pieces is also disclosed.
