The measure of [a hole in the bottom of] an earthenware vessel that will render it tahor [is as follows:]

That which was made for food,

its measure is with [a hole large enough to pass through it] olives;

that which was made for liquids,

its measure is with [a hole large enough to allow into the vessel] liquids;

that which was made for this [food] and that [liquids]

we take it to the stringent [measure] of olives.

פרק ג משנה ב

An [earthenware] barrel,

its measure [of a hole large enough to render it tahor] is with dried figs,

these are the words of Rabbi Shimon;

Rabbi Yehuda says,

with nuts

Rabbi Meir says

with olives.

The stewpot and cooking pot,

their measures are with olives.

The flask and the narrow-necked pitcher (usually used for oil),

their measures are with oil;

and the tzartzur (a pitcher with a long neck, usually used for water)

its measure is with water;

Rabbi Shimon says

All three (the flask, long-necked pitcher and tzartzur) are with seeds (which they are sometimes used to store).

A lamp,

its measure is with oil;

Rabbi Eliezer says

with a small coin (such are sometimes stored in a lamp).

A lamp whose mouth has been removed (these lamps are bowl shaped, with one opening at the top for oil to be added, and a second smaller hole in a projection from the side in for the wick; this projection and its hole is the mouth)

is tahor;

and [a lamp made] of earth (i.e. clay that has not been fired in a kiln)

whose mouth has been fired with the wick

is tahor (as the lamp is still considered unfinished).
