ABSTRACT:
According to this invention there is provided a method for producing glass mat using glass having a relatively high alkali content which comprises chopping the glass fibers while wet and thereafter freezing the wet fiber glass in order to prevent leaching of the alkali constituents. The frozen glass fiber can then be crushed and used to prepare a glass fiber mat in a wet process.
