Abstract
The invention relates to a method, comprising: feeding at least one molten-glass parison into a parison mold; forming, in the parison mold, a blank of an item from said at least one parison; transferring the blank of the item into a finishing mold; and forming the item in the finishing mold. While forming the item in the finishing mold, excess glass is directed out of the base of the item so as to form a convex bulge, and said bulge is removed such that the thickness of the base of the item is substantially constant.
