(VEN) - By investing in gas-fired and electric ovens, the villagers of Bat Trang Pottery Village in Hanoi’s Gia Lam District have revolutionized production and made their environment greener and cleaner.
|Craft villages need timely support policies to develop|
Shift away from coal
Bat Trang Pottery Village is an attractive destination for both domestic and foreign tourists. According to Ha Van Lam, Head of the Representative Committee of Bat Trang Pottery Village, the attraction of the craft village is not only in its beautiful and diversified products and cultural elements, but also in its greener and cleaner environment.
In the past, the air of Bat Trang Pottery Village was polluted by toxic smoke and dust emanating from the pottery burning process with firewood and coal. However, by the 1990s, 70 percent of the products were exported and the Japanese partner had different requirements for the design and stability of the firing temperature. In order to meet these requirements, Japanese experts supported Bat Trang with a gas kiln with a capacity of one cubic meter, creating stable and better products. Lam also emphasized that from 2005 to 2007, Bat Trang replaced all its coal-fired furnaces with gas furnaces.
The gas furnace model has been replicated in neighboring villages such as Kim Lan, Da Ton and transferred to a number of pottery craft villages in other provinces such as Hai Duong, Thai Binh, Binh Duong, Dong Nai and Song Be. The conversion from coal to gas furnaces is only one factor of the improved product quality, energy savings and limited environmental pollution. The support of scientists and artists in shaping products and mixing chemical ingredients in raw materials are also contributing factors, Lam added.
Electric, solar furnace power
Currently, Bat Trang residents mainly operate kilns according to folk experience, making the support of state management authorities in providing appropriate information on the firing technology and operational training essential.
Bat Trang is beginning to use electric furnaces to burn pottery. Although electric furnaces have no advantage in creating products with special enamel colors, they have economic value in burning products that require low temperatures and fast progress, especially tourism products.
Bat Trang could also apply solar power to dry product and furnaces with temperatures below 1,200 degrees Celsius, helping gradually replace liquefied gas, reduce production costs and improve the environment, Lam expected.
In order to save energy and improve production efficiency, Bat Trang villagers are seeking to invest in a tunnel kiln, a furnace that can save 30 percent of energy costs and other production costs. However, the village needs supportive and incentive policies to help it invest in the new heating technology to create a green living environment and sustainable production.
|Ha Van Lam, Head of the Representative Committee of the Bat Trang Pottery Village: In addition to state support in issuing policies to encourage the application of new technologies in production, Bat Trang needs support from science and the arts to create good quality products at reasonable prices.|
