The utility model belongs to the technical field of the glass shaping, specifically disclose a glass shaping material leaking tube, aimed at that the current glass shaping material leaking tube of solution can form the electrode heating blind area and lead to easily analysing the problem that brilliant glass analysed the crystalline substance. This glass shaping material leaking tube including material leaking tube body and the first electrode of setting on the material leaking tube body, still includes the heating jacket, the heating ways is established on the front end of material leaking tube body, and has the clearance between heating jacket and the material leaking tube body, and it has the insulation material to pack in this clearance. Putting into production when easily analysing brilliant glass, utilizing the heating jacket to the heating of electrode heating blind area, can improve the thermal conditions that adds in this region, temperature that rapidly will this region risesglass and analyses more than the brilliant temperature to restrain or improve and analyse the crystal bar line, do benefit to the hourglass material molding operation who easily analyses among the brilliant glass continuous production. The insulation material of filling can avoid the heating jacket electrically conductive on the one hand, and on the other hand can also keep warm to the electrodeheating blind area.
