Exodus 32:19-20

19And it came to pass, when he came near the camp, and saw the calf and the dancing, that Moses' anger burned, and he cast the tables out of his hands, and shattered them beneath the mountain.

20And he took the calf that they had made, and burned [it] with fire, and ground it to powder, and strewed [it] on the water, and made the children of Israel drink [it].
