[Avodah] zecher lechurban

[Eli Turkel]

<<The only one of these that appears to be consistently practiced (or
even widely known about) is the glass under the chuppa - and what do
we do the instant the glass is smashed, symbolising the churban? We
shout "mazel tov"! >>

In the halacha emails of ROY he objects strongly to saying mazal tov
at the breaking
of the glass.

BTW that is the reason some break the glass in the middle of the
ceremony rather than
at the end. Others sing "im eskachech" to explicitly connect the breaking of
the glass to the churban
