Hymir’s fortress was built of stone. Thor took the drinking cup, hefted itin both hands, then threw it with all his might against one of the granite pillars that  held  up  the  roof  of  the  banqueting hall.  There  was  an  ear-splitting crash, and the air was filled with blinding dust.When the dust settled, Hymir got up and walked over to what was leftof the granite pillar. The cup had gone through first one pillar, then another,breaking them into tiny fragments of stone. In the rubble of the third pillar was the drinking cup, a little dusty but quite undamaged.
