<p>A glass fiber composition comprises about 33-47 weight% SiO 2 ; about 18-28 weight% Al 2 O 3 ; about 5-15 weight% Fe 2 O 3 ; greater than or equal to about 2 weight% and less than 10 weight% R 2 O; about 8-30 weight% CaO; and less than 4 weight% MgO; wherein R 2 O represents alkali metal oxides. Preferably, the glass fiber composition has a liquidus temperature of less than 2350°F; and a viscosity at a liquidus temperature of the glass fiber composition of greater than 500 poise; and fire resistant glass fiber formed from the glass fiber composition has a biodissolution rate of greater than 50 ng/cm 2 /hr.</p> |
