The invention provides a glass outflow pipeline which can prevent any error from generating in the glass component of the outflow molten glass and which is also beneficial for producing high-quality glasses, a pipeline for producing the glass outflow channel, a glass producing device having the glass outflow channel, and a method for producing the glass forming body and the optical element of theglass outflow pipeline. Concave-convex shapes inside which the molten glasses are mixed by flowing are arranged on the inner periphery of at least one part of the glass outflow pipeline forming a channel through which the molten glasses stored inside a container is led out. Particularly speaking, the concave-convex shapes consist of spiral concave grooves and/or convex edges along the length direction. |
