Description: This frame shows two pellets of green anode paste that have coalesced. There is a large particle of petroleum coke at the left and an anode butt fragment on the right. The zone in the middle has an excess of void space due to a lack of pitch. Note the elongate shape of the voids. This area is a zone of weakness.
