Daf Hashavua

Bava Basra 60b

(Today's Daf)

על ראש שמחתי, אר"י זה אפר מקלה שבראש חתנים

The Kol Bo writes There are places where they don't place the ashes on the Choson's

head, because there are some Chasanim who don't wear Tefilin (פאר תחת אפר) ---

instead,  a כוס is broken after the שבע ברכות  to mourn the Churban Habayis.

This Kol Bo is the first source for breaking a כוס under the Chupa to mourn the Churban Habayis.

The Gemoro in Brachos where מר בריה דרבינא & רב אשי who at their son's weddings broke

expensive cups was not because of the Churban but to minimize excessive joy in Olam Hazeh. (ר' יונה)

The Minhag today, is that the mothers of Chosson Kallah are the ones who break the plate at the תנאים 

Perhaps the reason for this is because the תנאים originally was done at home. The woman of 

the house brought the plate from the kitchen. Since it was in her hands she was the one

to break it. אמבצי
