  • Publication number: 20200071222
    Abstract: A method of forming a strengthened glass article is provided. The method includes providing a strengthened glass article. The strengthened glass article is in the form of a container including a sidewall having an exterior surface and an interior surface that encloses an interior volume. The sidewall has an exterior strengthened surface layer that includes the exterior surface, an interior strengthened surface layer that includes the interior surface and a central layer between the exterior strengthened surface layer and the interior strengthened surface layer that is under a tensile stress. A laser-induced intended line of separation is formed in the central layer at a predetermined depth between the exterior strengthened surface layer and the interior strengthened surface layer by irradiating the sidewall with a laser without separating the glass article.

  • Publication number: 20190161377
    Abstract: A method of melting glass and glass-ceramics that includes the steps: conveying a batch of raw materials into a submerged combustion melting apparatus, the melting apparatus having liquid-cooled walls and a floor; directing a flame into the batch of raw materials and the melted batch with sufficient energy to form the raw materials into the melted batch; and heating a delivery orifice assembly in the floor of the submerged melting apparatus to convey the melted batch through the orifice assembly into a containment vessel. The melted batch has a glass or glass-ceramic composition that is substantially reactive to a refractory material comprising one or more of silica, zirconia, alumina, platinum and platinum alloys.
