L’invention a pour objet un substrat émaillé illuminable (et sa fabrication) avec une première feuille de verre (1) comportant une couche diffusante discontinue en émail, en un liant vitreux et des microcristaux. Figure 1
An enameled substrate includes a first glass sheet including, on a first main face, a scattering layer made of scattering enamel, including a vitreous matrix, the scattering layer including a first pattern having a width of at least 0.1 mm and a surface S0, the first pattern including a set of separate micropads of the scattering enamel, wherein, by defining within the first scattering pattern an analysis surface area S1 of less than S0, S1 being at least 50 μm by 50 μm and at most 100 μm by 600 μm, and a surface area S2 which is a sum of the surface areas of the micropads in the surface area S1, the first scattering pattern is defined by an equivalent mean diameter Am of the micropads of less than 10 μm and of at least 1 μm.
