Inkwells
It appears that there are two small jugs welded onto a piece of metal. Now, what purpose would this serve? Maybe it’s a weird tea set where you share the hot beverage with someone else from the same serving dish. The OP wanted to get to the bottom of this mystery once and for all.
Someone provided an answer right away. Turns out that this thing is actually two ink wells that people use to leave ink in when writing with a quill pen. You can either place two different ink colors in each jug, or fill one with water to clean the pen out when you’re done writing.
