Abstract: A method of minimizing the formation of a rhodium-platinum defect in a glass or glass ceramic material or in the melt thereof is provided. The method includes providing a vessel made of a platinum-rhodium alloy for use in a manufacturing process for obtaining the material, and an interface between the vessel and the melt is present. The method can include providing sufficient partial pressures of hydrogen outside and inside the vessel for controlling the partial pressure of oxygen in a region of the melt adjacent to the interface. A method of minimizing the formation of, or counteracting the impact of, a localized thermal, electrical, or composition cell in the melt during a manufacturing process is also provided. The method can include adding a multivalent compound to the melt, adding a mixer to the finer tube, adding a mixing step to the manufacturing process, or amplifying the mixing.

Abstract: Disclosed herein are delamination resistant glass pharmaceutical containers which may include a glass body having a Class HGA1 hydrolytic resistance when tested according to the ISO 720:1985 testing standard. The glass body may have an interior surface and an exterior surface. The interior surface of the glass body does not comprise a boron-rich layer when the glass body is in an as-formed condition.
