Abstract: A melting apparatus is disclosed, the melting apparatus including a melting vessel with a back wall, a front wall, a first side wall, a second side wall and a longitudinal centerline extending therebetween and a width between the first and second side walls orthogonal to the centerline. The melting vessel further includes a first feed screw including a first axis of rotation and a second feed screw including a second axis of rotation, the first axis of rotation positioned between the longitudinal centerline and the first side wall and the second axis of rotation positioned between the longitudinal centerline and the second side wall. The positions of either one or both the first and second axes of rotation are located from a respective side wall a distance that is equal to or less than about 15% of the width of the melting vessel.
