x1 is a jug, pitcher [carafe, ewer, flagon] containing x2, made of x3.
Also ‘amphora’. The second slot is a bottlecap (see the note under bolva). A djaga is a vessel for pouring, usually with a handle or a spout; some of them have lids or caps, but some don’t. [This word, just like bolva, is part of a rework of the container words.]
