A refractory glass fiber having a use temperature of greater than 1000.degree. C., up to at least 1260.degree. C., having an after service mechanical integrity comparable to conventional refractory ceramic fiber and which is non-durable in physiological fluids, consisting essentially of the product of silica, magnesia and optionally zirconia, is produced from a melt, optionally containing a viscosity modifier.

[ We claim:] [1.] A low shrinkage, high temperature resistant glass fiber having a use temperature up to at least 1260.degree. C., which maintains mechanical integrity after exposure to the use temperature and which is non-durable in physiological fluids, consisting essentially of a fiberization product of about 71 to about 78 weight percent silica, about 20 to about 27.5 weight percent magnesia, 0 to about 5 weight percent zirconia, 0 to about 2.5 weight percent alumina and 0 to about 1 weight percent boria.
