Lime is an important raw material. It is extracted as limestone by opencast mining, ground to limestone products or calcined in special kilns. Many products used in everyday life are impossible without lime. These are, among others, glass, sugar, paper as well as pharmaceutical and cosmetic products. The raw material is also indispensable in the construction materials industry. Iron and steel producers need limestone, in environmental protection it is used, for example, for air cleaning and drinking water purification. Therefore limestone and lime as well as products derived from them can be found everywhere. We use them daily even though we may not realise it at the time. The film explains types of limestone formations, how they are extracted and processed and their various ranges of application. It is divided into didactically meaningful sections thus presenting the “fascination of lime” in a logical sequence.
