(54) GLASS

I

The invention relates to glass for mechanized production of colored glass containers and other types of glass products.

Known glass 13, including, wt.%:

Si 02 55-63 A 10-20 TiO 0.1-1 MgO 0.3-3 IPO 0.3-4 Na2, .0 6-10 Fe, (0.1-1.2 RO12-20

Closest to the invention is a 2X glass composition comprising | wt.%:

Si From. 55-63 10-20

CaO 8-12 0.1-1

TiO 0.3-3

MgO

However, these glasses have a higher temperature of the upper limit of crystallization and the start of molding.

The aim of the invention is to reduce the temperature of the upper limit of crystallization of glass, the temperature of the beginning of the molding and the expansion of the safe interval of molding without deteriorating the NIN of the other cooking, working and physicochemical properties of the glass.

, 2-7,0la of crystallization is reduced, and the safeBaO0, 6-1.4 interval of molding is increased over

The use of manganese sludge charge for additional input into the glass allows to reduce the SiO content,

increase the input and Mn „0 and additional- 5 The resulting glasses have properties

It is advisable to enter BAO. Presented in Table. 2

To obtain glass, an optimal addition of barium oxide is prepared and four mixtures are welded; the composition is in the range of 0.6-1.4 wt.% Of these are presented in Table. 1. And with a further increase in its amount of glass on the basis of volcano-quality, the working characteristics of the ash of the Karyan deposit are not significantly changed, nor does the Chiatura Glass manganese sludge have different color deposits at 1420-1470 С in the shade from dark green to dark neutral or slightly oxidized brown and therefore can be a tire of gaseous medium. The glasses were used to produce products that were melted by means of medical, chemical, and food pressing. The temperature of the start of fore-glass containers, as well as for the production of rolling and the temperature of the top of some kinds of high-quality dishes.
