And when the woods and groves are felled, then are exterminated the beasts and birds, very many of which furnish a pleasant and agreeable food for man. Further, when the ores are washed, the water which has been used poisons the brooks and streams, and either destroys the fish or drives them away. Therefore the inhabitants of these regions, on account Therefore the inhabitants of these regions, on account of the devastation of their fields, woods, groves, brooks, and rivers, find great difficulty in procuring the necessaries of life, and by reason of the destruction of the timber they are forced to greater expense in erecting buildings. Thus it is said, it is clear to all that there is greater detriment from mining than the value of the metals which

Slag-sitalls — An effective structural material
Humans have been making iron and steel for centuries. Steel fuelled the industrial revolution and remains the backbone of modern industrialized economies. This article briefly explains how iron and steel made. Separate articles discuss how the material is converted into steel construction products and the basic material properties of steel that are used in design. As early as 6, years ago, early civilizations used iron ore found in meteorites to construct primitive tools. The first iron furnaces appeared in about BC.SEE VIDEO BY TOPIC: Becoming the World’s Leader in Producing Low Cost Green Solar Grade Silicon Metal

Embed Size px x x x x A Symposium by Correspondence has been organised on behalf of RILEM on the use of waste materials and industrial by-products in the construction industry. Information about individual materials has been extracted from the national contributions and a chapter devoted to each waste in turn. The properties, occurrence, present uses and possible future applications of each waste are described.
The main conditions for obtaining decorative glass and glassy-crystalline materials from technogenic raw materials overburden rocks, enrichment wastes, by-products of processing ores and concentrates, wastes of chemical industries are considered. Relationships between the composition of the secondary raw materials and a number of important technological properties are established. The compositions and conditions of the production of decorative glass and glass with special properties made of technogenic raw materials from Murmansk region are developed. The efficiency of the compaction of glass batches is studied and the increase in the melting speed of the tableted batch and the clarification rate of the glass mass are experimentally observed.

Glass and ceramic industry of the Ukraine on the 100th anniversary of the birth of V. I. Lenin
Enamels normally consist of alkaline boro- silicate glasses of complex composition. The vitreous or porcelain enamel is a composite material comprising a base metal and a glassy coating bonded chemically by fusion. It is generally divided into ground coats and cover coats. Ground coats contain adherence-promoting oxides for good bond to substrates while cover coats provide additional physico- chemical or cosmetic properties and require a ground coat as a primary layer. Most of the corrosion resistance and other me- chanical properties of the enamel coatings are determined by the enamelling raw material called frit; other factors can influ- ence them to a minor extent.

Glass-Ceramics Their Production
The invention relates to a flexible article suitable for producing substrates of flexible devices and the production process thereof. Flexibility is the trend of development of electronic devices. The substrate of a flexible device can be glass, metal foil and polymer. Polymer has flexibility and high surface smooth, but its temperature stability is low, not meeting the processing requirements of flexible devices, such as displays, lighting equipment, solar cells and so on.

Ceramics also known as fire clay is an inorganic, non-metallic solid article, which is produced by the art or technique of heat and subsequent cooling. The ceramics industry in India came into existence about a century ago and has matured over time to form an industrial base. From traditional pottery making, the industry has evolved to find its place in the market for sophisticated insulators, electronic and electrical items.
5. GLASS AND MATERIALS BASED ON MINERAL MELTS
Rawlings, J. Wu, A. ABSTRACT Glass-ceramics are polycrystalline materials of fine microstructure that are produced by the controlled crystallisation devitrification of a glass. Numerous silicate based wastes, such as coal combustion ash, slag from steel production, fly ash and filter dusts from waste incinerators, mud from metal hydrometallurgy, different types of sludge as well as glass cullet or mixtures of them have been considered for the production of glass-ceramics.
Use of waste materials in the construction industry
In steelmaking, impurities such as nitrogen , silicon , phosphorus , sulfur and excess carbon most important impurity are removed from the sourced iron, and alloying elements such as manganese , nickel , chromium , carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and entrained impurities termed "inclusions" in the steel is also important to ensure the quality of the products cast from the liquid steel. Steelmaking has existed for millennia, but it was not commercialized on a massive scale until the late 19th century. An ancient process of steelmaking was the crucible process.
