Abstract:
A method includes forming a glassy article. The glassy article includes a first glassy layer and a second glassy layer adjacent to the first glassy layer. The second glassy layer includes a photosensitive glass. The glassy article is exposed to radiation to form an exposed glassy article. The exposed glassy article is subjected to a heat treatment, whereby a plurality of inclusions is formed in the photosensitive glass of the second glassy layer.
Abstract:
An apparatus (10) for forming the outer layers of a glass laminate sheet comprises a reservoir (12), individual first (14a) and second (14b) distributors extending below and in fluid communication with the reservoir, and first (30a) and second (30b) slots positioned respectively at the bottom of the first and second distributors. The slots have a length, the distributors have sides and a middle, and the length of the slots on the sides of the distributors is desirably decreased relative to the length of the slots in the middle of the distributors. The apparatus is useful with a trough or isopipe (100) to provide clad glass streams to contact an over-flowing core glass on respective sides of the trough or isopipe.
