PURPOSE: A glass flowing management method by the thermal control is provided to improve the amount, the thickness, and the temperature distribution of molten glass on the surface of a producing apparatus. CONSTITUTION: A glass flowing management method comprises the following steps: forming a stream-tube-mapping in between the transverse section of a pipe(20) supplying molten glass(40) to a forming apparatus(60), and the outer surface of the forming apparatus; using the stream-tube-mapping for selecting the temperature distribution for the transverse section causing the desired amount, thickness and the temperature distribution of the molten glass; and heating or insulting the pipe to generate the desired temperature distribution. |
