Ashtray suddenly fractured

  1. Oct 22, 2012 #1
    We have an ashtray on an elevated table in our balcony.

    No one was outside and it suddenly fractured into 4 nearly even pieces on the table. Strangely enough, all the cigarette buds were lit.

    This is the ashtray we used:


    My question is, how do you think this thing suddenly broke with all the cig buds lit?
