Soldering iron Painting on Gourd has a long history of gourd pyrography, which is traditionally originated in the Han Dynasty and flourished in the Qing Dynasty. The homonym of gourd is "fortune", which represents fortune and auspiciousness in people's minds. The gourd artists use iron instead of pen to create characters, landscapes, flowers, birds and animals on the smooth and hard wooden surface of gourd by using the techniques of white drawing, fine brushwork and freehand brushwork of traditional Chinese paintings. The paintings show the effects of burning, black, brown, yellow, white and other levels and rendering of traditional Chinese paintings, which have high appreciation value and collection value.
