Abstract
Disclosed herein are methods for forming low melting point glass fibers comprising providing a glass feedstock comprising a low melting point glass and melt-spinning the glass feedstock to produce glass fibers, wherein the glass transition temperature of the glass fibers is less than or equal to about 120% of the glass transition temperature of the glass feedstock. The disclosure also relates to method for forming low melting point glass frit further comprising jet-milling the glass fibers. Low melting point glass frit and fibers produced by the methods described above are also disclosed herein.
