METHODS FOR DETERMINING CHEMICAL HETEROGENEITY OF GLASS CONTAINERS
A method including obtaining glass containers, and adding a solvent to 5.0% by volume to less than or equal to 50.0% by volume. Heating to an elevated temperature and cooling to room temperature. The solvent is consolidated and titrated, where an amount of a titrant is an as received titrant volume. Glass containers are etched, and a second solvent is added at 8.0% by volume to less than or equal to 25.0% by volume. The containers are heated to an elevated temperature and cooled to room temperature. The second solvent is consolidated and titrated, where an amount of a titrant is an etched titrant volume. The Chemical Durability Ratio (CDR) of the plurality of glass containers is calculated As Received Titrant Volume where: CDR=As Received Titrant VolumeEtched Titrant Volume. Etched Titrant Volume.
