Abstract
In one embodiment, a method of forming a glass container may include forming a glass container comprising a sidewall at least partially enclosing an interior volume. At least a portion of the interior surface of the sidewall may have an interior surface layer with a persistent layer heterogeneity relative to a midpoint of the sidewall. The interior surface layer of the glass container may be removed from the interior surface of the sidewall such that a modified interior surface of the sidewall has an interior region extending from about 10 nm below the modified interior surface into a thickness of the sidewall. The interior region may have a persistent layer homogeneity relative to the midpoint of the sidewall such that the modified interior surface is resistant to delamination.
