Gypsum
Present in nature in a soft evaporitic sedimentary mineral form, alabastrine and crystalline calcium sulphate dihydrate commonly known as gypsum is a raw material of fundamental importance in everyday life.
For more than five thousand years gypsum has undoubtedly represented a very significant element of the construction industry (Egyptian civilisation has left us remarkable evidence of its utilisation even in previous eras), moreover recent and modern technological progress has discovered innumerable properties that enable its useful utilisation in various sectors such as agriculture (fertiliser, soil amendment and corrective), pottery (mould creation), healthcare (excipient for pills, plastering and orthodontic impressions), enology (wine plastering), galvanoplastics (charge for material plastics), animal breeding (nutrient salts production and ammonia controlling litter addictive).
