מסכת כלים

פרק ל משנה ד

צלוחית קטנה

A small (glass) bottle

whose neck was removed (i.e. it was broken off, leaving jagged edges)

is tamei (as one could still use it);

and a large one whose neck was broken

is tahor (as the jagged edges make it difficult to safely use; in contrast to the small bottle, due to its size it would be hard from a person to avoid trying to hold it by its broken neck);

that of ointment whose neck was removed (a small bottle used to hold ointment, into which one would ordinarily insert one's finger)

is tahor

as is cuts

the hand;

large (glass) jars

whose necks were removed

are tamei

as one intends them for pickling (they were left alone for long periods of time, and so there is less concern that one would hurt oneself while carrying it);

and the and the grinder's hopper (this was a chute, wide at the top and narrow at the bottom, which fed grain into a mill) made of glass

is tahor.

Rabbi Yosi says,

"Fortunate are you (mesechas) Keillim,

as you entered with tumah (listing the progenitors of tumah)

and exit with tahara (this last case of the glass grinder's hopper)."

שנים טמאין במת אחד טמא טמאת שבעה ואחד טמא טמאת ערב שלשה טמאין במת שנים טמאין טמאת שבעה ואחד טמא טמאת ערב ארבעה טמאין במת שלשה טמאין טמאת שבעה ואחד טמא טמאת ערב כיצד שנים אדם הנוגע במת טמא טמאת שבעה ואדם הנוגע בו טמא טמאת ערב

If two people become impure from a corpse, one becomes impure for seven days and one becomes impure until evening. If three people become impure from a corpse, two become impure for seven days and one becomes impure until evening. If four people become impure from a corpse, three become impure for seven days and one becomes impure until evening. How do two [become impure]? One person touches a corpse and becomes impure for seven days, and any person who touches him becomes impure until evening.
