Description

(54) СТЕКЛО(54) GLASS

Изобретение относитс к стеколь-ному производству и может быть использовано в производстве художественных изделий из стекла.The invention relates to glass production and can be used in the manufacture of art glass products.

Известно стекло, включающее, мас.%: S 102 65; KjO 16; PbO 18.; 2; ZnO 1 1.Known glass, including, wt.%: S 102 65; KjO 16; PbO 18 .; 2; ZnO 1 1.

Это стекло имеет невысокую твердость (по Моосу 6,5-7), показатель преломлени 1,49-1,51.This glass has a low hardness (Mohs 6.5–7), and the refractive index is 1.49–1.51.

Claims

From the above examples it can be seen that the proposed compositions ensure the preservation of a high refractive index of glass without the use of lead oxide. This eliminates harmful evaporation during glass melting and thus improves labor conditions. The proposed glass has a higher hardness compared to the known, which makes it suitable for the manufacture of jewelry publications. The invention includes glass including SiOj, KjO, NSijO, CaO, MgO, characterized in that, in order to increase hardness, it additionally contains FejO 5, MoС, WQj, T i 0, and F in the following ratio of components, wt. %: SiO / g 48-51 KoO2-4 AliOj
