Russian to English Art/Literary Archaeology culinary implements

This is a photo caption for an archeological dig, where they are finding and cataloging the usual bits of pottery. The picture just shows an archeologist surrounded by piles of pottery, tools, and other flotsam and jetsam.

«Край тарелки. Миска археологически целая. Венчики кувшинов.»

I get that these are jars or pitchers, but can't figure out how the «Венчики» fits in. Google image searches didn't help.

Thanks in advance!
