The First Beacon Tower of the Great Wall of China -Multifunctional Coal Artwork of Zhenbeitai

The First Beacon Tower of the Great Wall of China -Multifunctional Coal Artwork of Zhenbeitai:
Coal, also known as “Black Gold" and "Sunstone". The coal formed 200 million years ago in the Jurassic period of Yulin, China, accounts for one-fifth of the national coal reserves, and according to records, there are traces of the use of coal in the Yulin area as early as the ancient Warring States period. Zhenbeitai, the first beacon tower of the Great Wall of China, was a military fortress with the role of a beacon and a defensive castle in ancient wars, and the Qingongcheng under its foot was a distribution center for border trade. This Coal Artwork is made of coal, coal concentrate and new activated carbon, restoring the original appearance of Zhenbeitai-the first beacon tower of the Great Wall of China, which has both practical functions such as aromatherapy, brush holder, ink stone, paperweight, air purification and desk office supplies. The shape of the Zhenbeitai multifunctional Coal Artwork is surrounded by a filigree gold edge process, which is one of the traditional crafts of ancient gold work. Filigree is a process in which fine gold, silver or other metal wires are pinched and soldered to the object in accordance with the curvature and twist of the ink pattern. Filigree enamel originated in Persia (present-day Iran) and matured in the fifth and sixth centuries. It spread from Persia to Arabia and the Eastern Roman Empire, and then to China in the Liao Dynasty. Both the carving and the filigree techniques are Chinese national intangible cultural heritage and are highly collectible. Moreover, this cultural and creative product won China's national gold medal at the China Tourism Commodity Competition in 2021, and will become a healthy and environmentally friendly product for international promotion.
