This is the discovery entry: "The alchemist has learned how to preserve a sample of oozes in a sealed bottle, which he can prepare for use as an extract. When the alchemist activates the extract, he actually throws the bottle at a square within 30 feet, releasing the ooze, which reconstitutes and attacks the closest creature. The ooze is not under the alchemist’s control, but is otherwise treated as a summoned creature. The ooze remains for 1 round per caster level, and decays into powder when the duration expires. If the alchemist has the infusion discovery, another character can use the infused specimen. Creating a bottled ooze requires an extract with a level equal to the ooze’s CR (so a CR 4 gray ooze requires a 4th-level extract)."
What is unclear to me if I need an actual sample of an ooze or if I am creating it from nebulous scratch. The entry starts with "preserve samples", so do I need to kill an ooze to get it? Alive or dead? How many samples does that get me? How long do they each last? How many oozes can I make out of a sample? Or am I over thinking this and the wording is largely fluff, as the entry ends with "creating a bottled ooze requires and extract..."?
