A method for producing a panel made of a composite material of substantially three layers including a first cover layer and a second cover layer, at least one of which cover layers is made of glass, and an intermediate layer of a synthetic resin, into which a decorative material which differs from the synthetic resin has been embedded. The method comprises the steps of providing a mesh having an upper side covered with discrete particles, adhering the underside of the mesh to a surface of the first cover layer, applying a liquid synthetic resin to the discrete particles and the mesh, applying the second cover layer on the liquid synthetic resin while the edges are sealed, and curing the liquid synthetic resin.
