First Quesh venom refinery

A refinery was built by the Galactic Republic on the planet Quesh to mine the valuable chemical venenit queshaaga during the Cold War between the Republic and the Sith Empire. However, contaminants polluted the refining process, causing the processed chemical&mdash;more commonly known as Quesh venom&mdash;to eat through the refinery's vats and the floor of the building. The refinery was heavily damaged by the incident, leading the Republic to build a new refinery by the year 3642 BBY.

Behind the scenes
The first refinery was first mentioned in the Codex entry for the Quesh Venom Refinery in Star Wars: The Old Republic, a video game released by BioWare and LucasArts in 2011.
