Abstract
In the technique for fiberizing glass by the use of a centrifugal spinner delivering glass streams into an attenuating blast, a novel spinner construction is provided, and provision is also made for increasing the production, while also providing for the use of glass of lower cost, and at the same time, reducing environmental pollution. Glass compositions and spinner alloy compositions particularly suited for use in accordance with the invention, are also disclosed.
