Honey on the skin: when does it constitute an interposing substance?
Halacha 2 teaches that honey, ink, milk, blood, and similar substances intervene only when dry; when moist, they do not constitute interpositions.
Question 2
A woman wearing a loose necklace immerses. What is the ruling?
Halacha 4 states that necklaces, rings, and bandages that are loose and not pressing against the skin are not considered interpositions because water can reach the body beneath them.
Question 3
What did Ezra ordain regarding a woman's hair before immersion?
Halacha 16 records that Ezra ordained that a woman should comb out her hair and then immerse immediately thereafter.
Question 4
Two hairs knotted together in one knot — is this a chatzitzah?
Halacha 15 states that two or more hairs knotted in one knot are not an interposition because water can penetrate through them. A single knotted hair, however, is a chatzitzah if the person objects to it.
Question 5
A chatzitzah is found on a woman's body after she emerges from the mikveh. When is she considered pure?
Halacha 23 rules that when an interposing substance is found after immersion, she is impure unless she can state with certainty that the substance was not present at the time of immersion.
