First step for making a lamp blown glass crane. Take a white colored glaze material rod with a diameter of 1cm and put one end on the outer layer of the blowtorch flame to preheat for 1-2 minutes. This step is obligatory for all colored glaze material rods before hot-moulded in order to avoid bursting and even injuring people due to quick heat. After melting and softening one end of the white colored glaze material rod, a black rod with a diameter of 0.5 cm is taken and heated in the fire. Use the softened black bar to draw three lines on the white bar, then shape the crane's tail by pinching and pulling the bar with tweezers.
