Abstract: Invention relates to lenticular sheets made of thermally or chemically hardened mineral glass used for decorative panels, to create three-dimensional visual effects combined with an encoded image. One of the advantages of invention is the fact that it is a proposed mineral lenticular sheet, which underwent chemical or mechanical hardening of its outer parts 18. This increases the mechanical strength and impact resistance. This aspect makes it safer for use under the influence of external factors and in contact with a person. This allows for applying the invention in large scopes in comparison with plastic lenticular screens. Pre-stressing is achieved by thermal or chemical hardening.
