ABSTRACT:
A novel solution of H.sub.3 BO.sub.3 dissolved in strong hydrochloric or nitric acid is used to etch fluoride glass preforms used to manufacture fluoride glass fibers. Because of the excellent cleaning ability of the present solution, as well as the absence of sub-micron deposits, the resulting fibers have excellent bending strength.
