The sprinkler is a special kind of flask, in which the base of the neck is almost fully shut.

By Pushing the neck downward at the time of manufacture, the craftsmen caused the walls to fold inward in such a way that a barrier, or diaphragm, formed between the body and neck.

Through the small aperture remaining in the center of this diaphragm, the vessel could be filled or emptied of its contents, drop by drop.

This may be the vessel referred to by the rabbis in the phrase
“a flask whose brim is squashed inside it ” (Tosefta Miqva’ot 6 {7}: 22).

Sprinklers apparently held oil, perfume, and other costly liquids. Their decorations
include mold-blown patterns, elements pinched from the walls of the bubble or applied to it (such as snake threads), and even cut designs.

Many of the sprinklers in collections and the few provenanced examples are ascribed to
Syria or Jordan.
