ABSTRACT:
A filter for molten metal having a high melting point is in the form of a net woven of glass yarns formed by twisting a multiplicity of glass fibers together. The glass fibers contain at least 75 wt. % of SiO.sub.2 and are thermally cured at a thermal shrinkage of 2.5 to 15%. The thermal shrinkage is expressed by (l-l')/.times.100 % wherein l is the length of the fiber before the thermal cure, and l' is the length of the fiber as thermally cured.
