The way, as per the invention, means activation of the glass surface before refining by de-alkalizing the formed product in 80 to 100°C distilled water bath for a period of 15 to 60 minutes. To the surface prepared in such a way, aluminium compounds nanopowder of 1 to 120 nm (preferably Al.(OH)3) is applied and then the product undergoes heat treatment: heating up and keeping at a transformation temperature range 580 +- 150°C, not exceeding the deformation temperature and final annealing to temperature values below 200°C. |
