Zusammenfassung:	Glass composition resistant to chemical media for the production of reinforcing yarns, comprises (mol.%): silica (67-72); zirconium oxide (5-9.5, preferably >= 7.5); another metal oxide (11-17); lithium oxide (0-5.5); potassium oxide (0-5.5); sodium oxide (less than 10); and calcium oxide (3-9), where the composition further comprises less than 1% of impurities comprising aluminum oxide, ferric oxide, chromium oxide, titanium oxide, magnesium oxide, strontium oxide, barium oxide and phosphorus pentoxide, and being free of fluorine. Glass composition resistant to chemical media for the production of reinforcing yarns, comprises (mol.%): silica (67-72); zirconium oxide (5-9.5, preferably >= 7.5); a metal oxide (I) of formula (R 2O) (11-17); lithium oxide (0-5.5); potassium oxide (0-5.5); sodium oxide (less than 10); and calcium oxide (3-9), where the composition further comprises less than 1% of impurities comprising aluminum oxide, ferric oxide, chromium oxide, titanium oxide, magnesium oxide, strontium oxide, barium oxide and phosphorus pentoxide, and being free of fluorine. R : Na, K and Li. Independent claims are included for: (1) a glass yarns for reinforcement of organic or inorganic material obtained form the composition; and (2) a glass yarn composition and organic or inorganic material comprising the glass yarns.
