The work considers mathematical models describing thermal processes in the framework of thermal processing of raw material mixture for cellular glass sponging. It is shown that the existing models do not completely reflect the physical processes occurring in the technology of cellular glass production. It is noted that kinetics of cell formation in cellular glass is a promising trend for improving the cellular glass technology.

Tailings from the Osor fluorite mines release large amounts of potentially toxic elements into the environment. This work is a proposal to remove these waste materials and use them as a raw material in the manufacture of glass. The chemical composition of the tailings was determined by X-ray fluorescence and the mineralogy by X-ray diffraction. Waste materials have SiO2, Al2O3 and CaO contents suitable for a glass production, but Na as NaCO3 has to be added. Two glass formulations, with 80–90% of the residue and 10–20% Na2CO3, have been produced. The crystallization temperatures, obtained by differential thermal analysis, were 875 and 901 °C, and the melting temperatures were 1220 and 1215 °C for the G80-20 and G90-10 glasses, respectively. The transition temperatures of glass were 637 and 628 °C. The crystalline phases formed in the thermal treatment to produce devitrification were nepheline, plagioclase and diopside in the G80-20 glass, and plagioclase and akermanite-gehlenite in the G90-10 glass. The temperatures for the fixed viscosity points, the working temperatures and the coefficient of expansion were obtained. The chemical stability of the glass was tested and results indicate that the potentially toxic elements of the tailings were incorporated into the glass structure.

The ISO14046 water footprint evaluation method was used in this study to calculate the water shortage footprint and water degradation footprint in plate glass production, in order to improve the water efficiency and management level in the production process of plate glass in China. A certain enterprise in Hebei province was selected for investigation in 2018. The results show that the water shortage footprint generated by the production of flat glass was 0.435 m3H2Oeq/weight box. The proportion at raw material production stage was the largest, being 86%, so the water consumption control in raw material mining and the circulating water system should be strengthened and improved to reduce the fresh water consumption. Water degradation footprint in flat glass industry mainly consisted of eutrophication and acidification footprints. The eutrophication footprint was calculated as 0.027 kgNO3-eq/weight box, and water acidification footprint was 0.271 kgSO2eq/weight box. The largest proportion occurred at flat glass production stage. It should be paid attention at this stage, to update the relatively clean production equipments and add the waste gas processing steps to reduce pollution discharge.

Glass Waste

In recent times, the selection and treatment of glass waste are implemented in processing plants where a secondary raw material (SRM) named glass cullet, which is suitable for glass production, and a waste containing a high percentage of glass (glass waste2) is obtained. In the literature, there are many studies conducted on the recovery of the cullet, while few are the studies on the recovery of the waste that is produced by cullet processing. According to the 2013 Joint Research Centre (JRC) Reference report, the cullet produces savings in terms of energy and raw materials. However, it has a high current cost and its availability is becoming difficult, therefore its use is not always economically advantageous. The goal and strategy of the European Union is zero waste. For this purpose, further treatment of glass waste has been investigated. Through the industrial treatment of the glass waste2, a glass waste3 constituted again by an SRM made of glass is obtained together with a high quantity of presumed SRM (e.g., heavy plastic, corks, iron, non-ferrous metals, etc.). The process treatment separating these SRMs from the glass waste3 is, in this case, a pilot plant that needs to be optimized in order to reach an economic and sustainable industrial process solution. In particular, the materials to be recycled are exploitable product fractions with different particle sizes and physical properties (such as density, shape and resistance). This research is based on data collected from a North Italy process plant and is aimed at solving the issue of waste in this kind of process by implementing a pilot plant already present. Representative samples of feed material (glass waste3) and different products of the pilot plant have been analyzed. Moreover, laboratory tests were executed to improve separation efficiency and to valorize the different product fractions. A flow sheet of a new treatment plant has been developed and an economic evaluation has been made. The materials that will be separated in the new plant could be traded as SRM—e.g., plastics, metals, synthetic and cork stoppers—which constitute almost 90% of the total feed of the plant.

The process of the raw materials mixture heat treatment in the foam glass production is of great importance in the formation of the finished product thermal characteristics. Selection of optimal temperature regimes at the stages when the process of glass particles melting is activated and thermal decomposition of the gasifier occurs is of particular importance. Otherwise, a situation when the gasifier has decomposed by mass on the layers close to the material surface at that the reaction has not been initiated at the raw materials mixture center may emerge. The problem can be solved by the uniform heating throughout the raw materials mixture entire volume. The fact that excessive heating can entail additional financial costs for manufacturers’ energy resources and as a result the cost of the material can be increased and affect its competitiveness among thermal insulation materials should be taken into account. A method for calculating temperature fields allowing to simulate the thermophysical heating process in the center of the material under study on the basis of its surface temperature indicators has been presented in the paper. Such an approach may make calculation of the rational time intervals for the raw material mixture heat treatment prior to the foaming stages and partially optimization of the production process possible.

The Middle Ages

Scientific research and a series of important archaeological discoveries in recent years have opened up new perspectives on the study of ancient glass. Glass production seems to have been organised on a hierarchical basis. The primary workshops, mainly concentrated on the Syro-Palestinian coast, prepared the raw material by fusing sand from the river Belus with natron from Egypt. The product was then sent in blocks to all secondary workshops, the organisation of which was less elaborate. Here work was limited to re-fusing material that had already been worked. The widespread commercial movement of raw glass from East to West seems to have only come to a halt in the 9th c., when the export of natron from Egypt stopped. Consequently, a different flux was used, which was incompatible with the oriental sand. The adoption of local raw materials in the place of natron meant that the management of the entire production cycle became gradually autonomous, at different speeds and in different ways, during the course of the Middle Ages.
