A small flask whose neck was removed remains susceptible to uncleanness, But a large one whose neck was removed becomes pure. [A small flask] of spikenard oil whose neck was removed becomes pure, since it scratches the hand. Large flagons whose necks were removed remain susceptible to uncleanness, since they are adapted for the use of holding pickled foods. A glass funnel is clean. Rabbi Yose said: Happy are you Kelim; for you began with uncleanness, but you ended with cleanness.
