The deepest and thickest part of the olive is right up front, but it continues into the rear dome and skirt as well. This piece has odd marks on half of the base which I attribute to lehr conveyor contact, but that is a personal opinion. XO on dome. Cold glass lines, bubbles and a bit of firebrick round out the character. Very short vertical annealing crack up from base at rear keeps it from being mint. $15 plus regional rate shipping cost.
