1. A method of reducing bubble lifetime in a glass making process, comprising:
forming a first molten glass in a melting vessel;
directing the first molten glass through a conditioning vessel downstream of the melting vessel, the conditioning vessel comprising a free volume above a free surface of the first molten glass in the conditioning vessel; and
flowing an enrichment gas comprising a volatile material into the free volume, the volatile material reducing a surface tension of the first molten glass in the conditioning vessel, wherein a source of the volatile material is a second molten glass.
