ABSTRACT:
An acid-soluble glass used in manufacture of a flexible fiber optic bundle and a process for manufacturing a flexible fiber optic bundle using the glass. The glass has a composition expressed by mol percent comprising more than 15.0% and less than 41.0% of SiO.sub.2, more than 29.0% and less than 54.0% of B.sub.2 O.sub.3, more than 6.0% and less than 23.0% of BaO, and more than 5.0% and less than 19.0% of at least one alkali metal oxide selected from the group consisting of Na.sub.2 O, K.sub.2 O and Li.sub.2 O, the total amount of SiO.sub.2, B.sub.2 O.sub.3 and BaO being more than 71.0% and less than 80.0%.
