Glass compositions useful for forming fibers which are readily able to be degraded in a physiological medium such as that found in a human body. Advantageous compositions formed according to the present invention comprise the following components, set forth in percent by weight
SiO.sub.2 : 57 to 70%
Al.sub.2 O.sub.3 : 0 to 5%
CaO: 5 to 10%
MgO: 0 to 5%
Na.sub.2 O+K.sub.2 O: 13 to 18%
B.sub.2 O.sub.3 : 2 to 12%
F: 0 to 1.5%
P.sub.2 O.sub.5 : 0 to 4%
Impurities: less than 2%
