Abstract: A fining package for a glass composition may include a sulfate or a sulfide in an amount from about 0.001 to about 1 mol % of the glass composition. The fining package may include a multivalent compound, such as CeO2, SnO2, or Fe2O3, in an amount from about 0.001 to about 1 mol % of the glass composition. The fining package may be sulfide-free. The fining package may be free from a reducing agent for reducing sulfate to sulfide. The fining package may be free of at least one of Cl, F, Sn, Ce, and As. The glass composition may be used to form glass tubing. The glass tubing may be used to form a pharmaceutical packaging.
