The annual Harbin International Ice and Snow Sculpture Festival has been held since 1963. It had been interrupted for a number of years during the Cultural Revolution until it was resumed in 1985.
Harbin is located in Northeast China under the direct influence of the cold winter wind from Siberia. The average temperature in summer is 21 degrees Celsius and -17 degrees Celsius in winter. It can be as cold as -38 degrees Celsius in winter.
Officially, the festival starts January 5th and lasts one month. However the exhibits often open earlier and stay longer, weather permitting. Ice sculpture decoration technology ranges from the modern (using lasers) to traditional (with ice lanterns).
Swing saws are used to carve ice into blocks, taken from the frozen surface of the Songhua River.Chisels, ice picks and various types of saws are then used by ice sculptors to carve out large scaled ice sculptures, many of them intricately designed and worked on all day and night prior to the commencement of the festival. Deionised water can also be used, producing ice blocks as transparent as glass to make clear sculptures rather than translucent ones.Multicoloured lights are also used to give colour to ice, creating variations on sculptured spectacles when lit up especially at night. Some ice sculptures made in previous years include: buildings and monuments of different architectural types and styles, figures including animals people and mythical creatures, slippery dips or ice slides and lanterns.
Apart from winter recreational activities available in Harbin, these exquisitely-detailed, mass-produced ice sculptures are the main draw card in attracting tourists around the world to the festival.
