The breaking of a glass with a solid stomp of the foot comes from Jewish tradition, and is a recognizable element in many fictional weddings depicted on film and stage. Traditionally a glass is broken by the groom and attendees shouts “mazel tov,” which marks the end of the ceremony and the beginning of the celebration.

Traditional Jewish significance of breaking a glass
Rabbis have written no small amount the symbolism of breaking a glass during a wedding. In a traditional ceremony there are two cups used; one for the betrothal, and another for the nuptials. Its breaking is believed by some scholars to represent the destruction of the temple at Jerusalem, and the hope that the relationship with Jews and their deity might be restored as surely as glass can be melted and repaired. Others have argued that it is intended to temper the unbridled joy and intoxication that such a celebration might encourage; there are stories of rabbis who broke a glass to shock guests into sobriety. Yet another interpretation is that the act captures some of the essence of a Talmudic observation that “joining two people in marriage is as difficult as splitting the sea.” Breaking a glass in joy can also be seen as an attempt to counteract the divine consequences of the breaking of the tablets by Moses, which was done out of anger.
Contemporary symbolism of breaking the glass
When I’ve witnessed a glass being broken, it’s always been an acknowledgment of Jewish custom. Rather than using one of the ceremonial cups as might be dictated by strict adherence to tradition, a glass—sometimes a light bulb instead, because it sounds more dramatic—is wrapped in a cloth and placed before the groom. The guests I’ve spoken to have had different interpretations of its meaning than the rabbis who study these questions. These include:
- representing the suffering that Jews have endured throughout their history,
- a blessing that the marriage shall last as long as it would take to reassemble the glass,
- that this is the last time that the groom will “put his foot down,”
- a reminder, by smashing something valuable, that marriage is not about material possessions,
- a charm to transfer the cracks that might grow in this relationship to the glass instead, and
- a reminder of the fragility of human relationships, and that both joy and sadness lie ahead.
A cultural conclusion to a wedding
Breaking of a glass carries a lot of symbolism, and specifically calls back to Jewish culture and heritage. It’s a satisfying way to conclude a wedding ceremony, and invariably is followed by joy and celebration. It may be an appropriate finish to the ceremony, even if it’s not one performed by a rabbi and drawing upon the more sacred Jewish traditions, if recognizing Jewish heritage is important to those being married and their families.
