The present invention relates to an illuminating glass panel which includes: a first transparent sheet (1) of glass or plastic having a first main surface (11), a second main surface (12) and a side surface (13); a flat waveguide (3) having a first main surface (31), a second main surface (32), an injection side surface (33) and a bevelled side surface (34), opposite the injection side surface; a light source (2), preferably an LED module, positioned opposite the injection side surface (33) of the flat waveguide (3), the flat waveguide (3) being attached via the second main surface (32) thereof to the first main surface (11) of the first sheet of glass (11). The present invention relates to an illuminating glass panel which includes: a first transparent sheet (1) of glass or plastic having a first main surface (11), a second main surface (12) and a side surface (13); a flat waveguide (3) having a first main surface (31), a second main surface (32), an injection side surface (33) and a bevelled side surface (34), opposite the injection side surface; a light source (2), preferably an LED module, positioned opposite the injection side surface (33) of the flat waveguide (3), the flat waveguide (3) being attached via the second main surface (32) thereof to the first main surface (11) of the first sheet of glass (11). The subject matter of the invention is a process for producing a ceramic part, in particular a porcelain tile, characterized in that it comprises the following steps: preparing a composition of inorganic powders, forming this composition according to the shape of the rectangular part with unprocessed dimensions LU × WU × TU larger than those of the final dimensions LF × WF × TF of the product, machining the part to the dimensions LM × WM TM including the shrinkages ε, δ and o anticipated upon baking, baking in an oven according to the characteristics of the composition of powders, and obtaining the baked porcelain part with the final dimensions LF × WF × TF. The invention also covers the associated device. |
