Method for forming crystal-free glass fibers

Claim 1

THE METHOD OF PRODUCING SUBSTANTIALLY CRYSTAL-FREE GLASS FIBERS WHICH ARE PERMANENTLY FREE OF CRYSTALS, THE METHOD INCLUDING THE STEPS OF FORMING A POOL OF MOLTEN GLASS, WHICH POOL HAS ONE OR MORE AREAS IN WHICH A PORTION OF THE MOLTEN GLASS TENDS TO STAGNATE AT A TEMPERATURE LOWER THAN THAT IN OTHER PORTIONS OF THE POOL, THE TEMPERATURE OF SAID OR MORE AREA BEING SUFFICIENTLY LOW THAT ONE OR MORE CONSTITUENTS OF THE GLASS TENDS TO COME OUT OF SOLUTION IN CRYSTA FORM, ADDING GLASS BATCH TO ONE PART OF THE POOL, ADDING A NUCLEATING AGENT TO THE GLASS, MELTING THE GLASS, MOVING PART OF THE MOLTEN GLASS THROUGH SAID ONE OR MORE AREAS AFTER THE NUCLEATING AGENT HAS BEEN ADDED, FORMING A MULTIPLICITY OF NUCLEI IN THE GLASS BY VIRTUE OF THE NUCLEATING AGENT, ON WHICH NUCLEI CONSTITUENTS IN THE GLASS CAN FORM INTO A MULTIPLICITY OF MINUTE CRYSTALS WHICH ARE SMALLER THAN THOSE WHICH WOULD OTHERWISE FORM, MOVING THE GLASS WITH THE SMALL CRYSTALS THEREIN THROUGH AREAS OF HIGHER TEMPERATURE TO CAUSE SAID CRYSTALS IN THE GLASS TO DISSOLVE, AND SUBSEQUENTLY FORMING FIBERS FROM THE GLASS AT ANOTHER PART OF THE POOL SPACED FROM SAID LOWER TEMPERATURE AREAS AFTER THE MINUTE CRYSTALS IN THE GLASS HAVE SUBSTANTIALLY DISSOLVED.

Claim 2

THE METHOD OF PRODUCING SUBSTANTIALLY CRYSTAL-FREE GLASS FIBERS WHICH ARE PERMANENTLY FREE OF CRYSTALS, THE METHOD INCLUDING THE STEPS OF FORMING A POOL OF MOLTEN GLASS, WHICH POOL HAS ONE OR MORE AREAS IN WHICH A PORTION OF THE MOLTEN GLASS TENDS TO STAGNATE AT A TEMPERATURE LOWER THAN THAT IN OTHER PORTIONS OF THE POOL, THE TEMPERATURE OF SAID OR MORE AREA BEING SUFFICIENTLY LOW THAT ONE OR MORE CONSTITUENTS OF THE GLASS TENDS TO COME OUT OF SOLUTION IN CRYSTA FORM, ADDING GLASS BATCH TO ONE PART OF THE POOL, ADDING A NUCLEATING AGENT TO THE GLASS, MELTING THE GLASS, MOVING PART OF THE MOLTEN GLASS THROUGH SAID ONE OR MORE AREAS AFTER THE NUCLEATING AGENT HAS BEEN ADDED, FORMING A MULTIPLICITY OF NUCLEI IN THE GLASS BY VIRTUE OF THE NUCLEATING AGENT, ON WHICH NUCLEI CONSTITUENTS IN THE GLASS CAN FORM INTO A MULTIPLICITY OF MINUTE CRYSTALS WHICH ARE SMALLER THAN THOSE WHICH WOULD OTHERWISE FORM, MOVING THE GLASS WITH THE SMALL CRYSTALS THEREIN THROUGH AREAS OF HIGHER TEMPERATURE TO CAUSE SAID CRYSTALS IN THE GLASS TO DISSOLVE, AND SUBSEQUENTLY FORMING FIBERS FROM THE GLASS AT ANOTHER PART OF THE POOL SPACED FROM SAID LOWER TEMPERATURE AREAS AFTER THE MINUTE CRYSTALS IN THE GLASS HAVE SUBSTANTIALLY DISSOLVED.
