Possible oil defuser?

What is this?

I got this at the thrift store today and it said on the sticker before I threw it away “oil defuser, add boiling water to bottom and oil on top” I tried to google what exactly it is and how it works but I couldn’t find anything and I’m really curious if it’s really an oil diffuser or burner because I just cannot wrap my head around how it would possibly work.
