(54) Calcium-sodium silicate green glass for food<br />
packing, absorbing the ultra-violet radiation<br />
and permeable for visible light<br />
(57) The invention refers to calcium-sodium silicate<br />
green glass for food packing, absorbing the<br />
ultra-violet radiation and permeable for visible<br />
light.<br />
The glass contains, in mass %: SiO 2 -<br />
50,00…82,50; Al 2 O 3 - 0,0001…4,00; CaO -<br />
3,00…25,00; Na 2 O - 12,00…25,00; Fe 2 O 3 -<br />
2,50…10,00; impurities - ≤ 5,00, the ratio<br />
Fe(II)/Fe(II) + Fe(III) constituting 0,05…0,25.<br />
The result consists in the selective absorption<br />
of the ultra-violet radiation by mixed valent iron<br />
ions.<br />
