Abstract (en)
A tempered glass sheet (1), with at least one of its faces (2) matted to determine the writing surface of the corresponding writing board, preventing reflections and allowing to view slides on said surface (2) of the glass sheet (1) which makes up the board. On the opposite surface (2'), which may be matted or not, is applied a serigraphy layer (3) of vitrifiable enamel, which layer (3) determines the required opacity. The board may also comprise a tempered glass sheet and another normal glass sheet, and between these the opacity layer, which may consist of the means of attachment of the glass sheets, such as polyvinyl butyral, which will preferably be white in colour, or of by serigraphy of the surface behind the writing surface, in which case the attachment layer will be transparent. <IMAGE>
