a seemingly large machine appears out of nowhere. two separate booths connected to two tubes and two sets of knobs. first one being the each sets of refining process, from Rough, Coarse, 1:1, Fine, and Very Fine, and the second one being the mainspring to activate the refining process.

"Hello. I am SCP-914, codenamed "The Clockworks". I am a machine that refines items to either a much more better one, or worse. Put any item on the intake booth and set the refining process."
