The tendency of container glass obtained from a mixture of green cullet with 10 - 50% colorless or brown to foaming has been estimated. An indirect method was used, which consists in controlling the apparent density of pelletized samples heat-treated at temperatures of 800, 1000, and 1200 ° C. It was found that the density reaches a maximum at 1000 ° C due to sintering and compaction and decreases to 1200 ° C due to a decrease in the solubility of gases and foaming. The density of samples fired at 1200 ° C from oxidized (green) and reduced (brown) glass decreases, and from a mixture of oxidized (green + colorless) glasses increases. Therefore, loading brown crusts into a green glass furnace is unacceptable due to the high risk of melt foaming. Tab. 1, ill. 3, bibliography: 5 titles.

The effect of oxides of rare earth elements (WO ₃, Gd ₂ O ₃, Y ₂ O _{3 < / sub>) for a set of technological and physicochemical characteristics of optical glasses for a light-guiding core. Compositions of glasses for optical fiberglass are synthesized that satisfy the basic requirements for them. The specified glass compositions can be used in the manufacture of fiber optic products.

One of the priority directions of diversification of JSC "BKO" is the production of products for the glass industry. In addition to the production of traditional aluminosilicate refractories, JSC "BKO" develops and produces new types of refractory materials, performs preliminary bench assembly of furnace design elements (bottom, arches of charging pockets, sub-nozzle arches, feeder trays). Specialists of JSC "BKO" provide engineering services for the design of individual units of a glass-melting furnace using materials of its own production. All design solutions are accompanied by recommendations for the performance of lining work and the setting of the lining to the operating mode. Tab. 2, ill. 6, bibliography: 7 titles.

The issues of safety of super-sized sheet glass of 6x; 3 m when transporting it in railway wagons. The design of an A-shaped transportation pyramid and a sealing shelter, consisting of a removable cap, two stationary end platforms and two removable side platforms, are presented. Removable and stationary platforms of the sealing shelter additionally function as assembly ladders when loading and unloading glass. Il. 3.

A comparative analysis of magnetic separators used to reduce and stabilize the iron content in quartz sand has been carried out. It is shown that obsolete electromagnetic roller and rotary separators are bulky, unreliable and expensive to operate. The design of permanent magnet belt roller separators has a number of irreparable defects that impede their use in the conditions of domestic enterprises. Thus, drum magnetic separators with a high-intensity magnetic system of the LMO series are most applicable for magnetic enrichment of quartz sand in the conditions of domestic enterprises.

Models have been developed that describe the dependence of the glass shape on the tempering regime. Simulation modeling of the control algorithm for the process of tempering automobile glass has been carried out. The possibility of further improving the quality of the produced glass is shown. The effectiveness of the use of simulation modeling in the development of corrective actions in the production of tempered glass has been substantiated. Tab. 5, bibliography: 2 titles.

The work of the enterprise to expand the range and improve the quality of products is shown. During the reconstruction of the glass container shop, the operation of the furnace was improved, the batch dosing system was updated, the chemical composition of the glass was changed, and the output control of products was tightened. As a result of these and other works, the quality of products has been improved, and its range has been expanded.

Shown is the work of a polished glass company. Refractories are produced for the needs of the company and to order. The production of mullite bottom bar has been mastered. An integrated quality management system was introduced. The company's products are of high quality. Tab. 2., ill. 2.
