Claim 25:
26. A method for storing a pharmaceutical formulation, the method comprising:
providing a batch of raw materials comprising one or more of SiO2, B2O3, Al2O3, alkali oxides, alkaline earth oxides and fining agents;
heating the batch of raw materials to form a glass melt;
forming the glass melt into a glass tube having a Type 1 glass composition according to ASTM Standard E438-92(2011);
re-forming the glass tube into a plurality of glass containers, each of the plurality of glass containers comprising a glass body having a wall portion with an interior surface and an exterior surface, a heel portion, and a floor portion, wherein the interior surface of each of the plurality of glass containers is formed by the interior surface of the glass body such that the interior surface of each glass container consists of the Type 1 glass composition, and wherein each of the plurality of glass containers does not comprise a boron-rich layer on the interior surface of the glass body, each of the plurality of glass containers comprising at least a class A2 base resistance or better according to ISO 695, at least a type HGB2 hydrolytic resistance or better according to ISO 719 and Type 1 chemical durability according to USP <660>;
applying a coating having a thickness of less than 100 microns to the exterior surface to at least one of the plurality of glass containers such that the at least one glass container with the coating has a coefficient of friction less than or equal to 0.7;
placing the plurality of glass containers on a pharmaceutical filling line; and
filling each of the plurality of glass containers with a pharmaceutical formulation.
