Development of Glass Production Technology

Popis výsledku v původním jazyce

Determination of the provenance of glasses is possible on the basis of their chemical composition and determination of the used input raw materials - glass-forming substances (SiO2) and alkaline flux (flux). The first raw materials for glass production were coastal sand from the Mediterranean Sea and alkaline raw materials (soda or vegetable ash). Sodium is a natural mineral mixture of sodium salts (NaHCO3, Na2SO4, NaCl…) and has been used for glass production since about the 4th century BC. Soda glasses are characterized by a high proportion of Na2O (13 - 20 wt.%) And a CaO content of around 5 - 9 wt.%. The contents of K2O and MgO are very low, below 1.5 wt.%. In addition to SiO2, CaO (5 - 10 wt%) and other impurities (eg Al2O3, Fe2O3 - contained in feldspar (feldspar), ZrO2 or TiO2) were introduced into the coastal sand.
