    Abstract: A method for shaping the mouth of a hollow precursor made of glass is provided, as well as glass produced thereby. The method includes heating the mouth of the hollow precursor; introducing a mandrel along a first direction into the mouth while the hollow precursor is rotating; and pressing shaping rollers along a second direction on an outside of the mouth while the hollow precursor is rotating with the mandrel in the mouth. The first and second directions are perpendicular to one another. The method can include moving the mandrel along second and/or third directions together or separate from expanding the mandrel along the second and third directions.
