Abstract
Abstract A decorative vitreous article is produced by blowing a glass parison in a mold against a coherent flexible web of glass fibers which thereby become partly or entirely embedded therein. After reheating, possibly by immersion of the parison in a bath of molten glass to cover exposed web portions by a further glass layer, the resulting body is blown into its final shape.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
A method of making a hollow vitreous article with a decorative pattern, comprising the steps of: (a) providing a flexible woven fabric of glass fibers forming intersecting warp and weft threads; (b) cutting said fabric to a size fitting into a given blow mold; (c) placing the cut fabric in said blow mold; (d) blowing a glass parison in said mold into contact with said fabric with at least partial penetration of the interstices of said fabric by the expanding glass mass whereby at least portions of said fibers are embedded in said mass; (e) reheating said parison with the fabric adhering thereon into a blowable state; (f) expanding the reheated parison and fabric by a further blow into a body of predetermined final shape; and (g) allowing said body to cool.
Claim 2

Claim 3
Dependent Claim
35 words

Claim 4
Dependent Claim
17 words
A method as defined in claim 1 wherein said fibers have a diameter not exceeding 13 microns.
Claim 5
Dependent Claim
24 words
A method as defined in claim 1 wherein said fibers initially have an optical appearance different from that of the glass forming the parison.
