Maqolada shisha idishlar ishlab chiqarishda qo'llaniladigan kvars qumi hom ashvosiga qo'yilgan zamonaviy talablar bayon qilinib O'zbekistondagi kvars qumining asosiy konlariga tavsif berilgan. Yuqori sifatli shisha idishlar ishlab chiqarishda dastlabki kvars qumi namunasini boyitish texnologiyalari asosida sifatini yaxshilash mumkinligi, bunda qo'shimcha ravishda 750-800 °C haroratda qumni quritish va keskin sovutish hisobiga qum donachalarini yuzalarida g'adir-budirlik hosil qilish mumkinligi ko'rsatib berilgan, 0.4-0,1 mm o'lchamdagi tarkibida lemir oksidlari miqdori 0,04-0,03 % bo'lgan kvars qumlari olish imkoniyatlari bayon qilingan.

The article presents the main requirements fo r quartz raw materials for the production of container glass and analyzes a number of characteristics o f the main quartz sand deposits in Uzbekistan. It has been established that in order to produce high-quality container glass used fo r canning agricultural products in Uzbekistan, it is necessary to subject the original quartz sands to the enrichment and heat treatment process of 750-800 С of grains upon drying, which allows get particles with a size of 0.4-0.1 mm and iron oxide content in an amount of 0.04-0.03%, characterized by high ratesin comparison with other quartz sands.
Key words: quartz sand, chemical composition o f quartz sand, iron impurities, granulometric composition, quartz sand enrichment, glass charge, container glass, physical and technical characteristics o f glass, technology o f enrichment, enrichment plant, automated lines, installation works, glass mass, heat consumption, automatic control, cooking glass, modern requirements, main parameters of cooking glass.
