摘要

In the method of forming a glass layer on a substrate by centrifuging as disclosed in the parent Specification, the glass particles are suspended in a fluid with a dielectric constant lying between 6 and 33.6 and a further, heavier, fluid is interposed between the substrate and the colloidal suspension, such fluid having a dielectric constant less than 9.
