Vat

A vat was a large container that could hold or preserve large objects like clones. In 35 ABY, Supreme Leader Kylo Ren traveled to the planet Exegol in order to locate and kill the resurrected Darth Sidious. Palpatine told Kylo Ren that he made Snoke, after which Kylo Ren walked by a vat that was holding clones of Snoke floating in natural liquid.
