Spun bamboo, an 800-year-old Vietnamese invention, is a fascinating creative technique used in crafting bamboo-made products. This traditional method has deep-rooted cultural significance and is an integral part of Vietnam's handicraft industry. In this article, we will dig deep into the process of Spun Bamboo production, from the preparation of bamboo material to the spinning process, finishing techniques, and its diverse applications.
SPUN BAMBOO – A RENEWABLE AND ECO PRODUCT
Bamboo is naturally found in Vietnam and is cultivated in both the highlands and delta regions of the country. Bamboo is known for its rapid growth, allowing it to be harvested every 3 to 5 years.
Bamboo is widely recognized as a sustainable and environmentally friendly resource. After bamboo is harvested, the remaining portion of the cut stem is left in the ground, enabling the rapid growth of a new bamboo plant. This entire growth cycle restarts automatically without requiring extensive care or attention.
SPUN BAMBOO PREPRODUCTION
Bamboo Selection: The bamboo used for spun bamboo is typically cut at the knot, leaving a segment of about 70 to 80 cm in length. This convenient size allows it to be easily transported to the handicraft villages.
Soaking in Water-Mud Mixture: Upon arrival at the village, the bamboo is placed in a water-mud mixture for approximately 90 days. This extended soaking process serves several crucial purposes:
Sugar Content Removal: It effectively removes the sugar content from the bamboo, making it more durable and resistant to damage.
Mold Prevention: Soaking in mud for this duration prevents the bamboo from developing mold , ensuring its long-lasting quality.
Insect Infestation Control: The treatment also helps control bamboo from insect infestation, ensuring that the material remains pest-free.
Drying in Sunlight: After the soaking process, the bamboo is removed from the water-mud mixture and left to dry in the natural sunlight. This step prepares the material for the subsequent stages of spun bamboo production.
SPUN BAMBOO SPINNING
The core of spun bamboo production is the expertise of local artisans who skillfully transform bamboo into various functional forms. Here is the breakdown of the process:
Bamboo Splitting & Cutting: Once the bamboo is completely soaked and dried, it is carefully split and cut into smaller pieces. The specific dimensions of these cut bamboo pieces will be determined by their intended purpose and desired shapes.
Bamboo Shaping: Specialized machinery is used to transform bamboo pieces into round shapes, which are then bent and glued together. Typically, this is done while the pieces are in a flat form.
Forming the desired shape: The round shapes are bent or pulled over ceramic or wooden molds to achieve the required size and shape.
Gluing and drying: The bamboo pieces are dipped in a glue mixture again and left to dry, typically in a designated drying room to maintain a moisture level of around 6 to 8%.
This entire spinning process, along with gluing and drying, typically takes place within the households of the spun bamboo handicraft village.
How the Spun Bamboo Bases are Finished
Once the base of spun bamboo products is finalized, the raw bases are usually transported to a larger factory for completion. The purpose of this step is primarily to centralize the management of painting, quality assurance, and packaging within a more extensive facility.
The production of spun bamboo involves a significant amount of manual labor and hand sanding. Most of the steps in the process require manual execution. Similar to numerous other Vietnamese manufacturing processes, spun bamboo is meticulously sanded multiple times to ensure a highly smooth surface.
Here are some of the basic steps used to finish spun bamboo products:
Clay is applied to the bases: Clay is placed on the spun bamboo base where the lacquer will be painted, followed by sun drying and sanding between coats.
Applying lacquer onto the prepared bases: Depending on the finish, multiple layers of lacquer will be applied to the surface. Lacquer paint can be used in various colors and can achieve either a shiny or matte finish.
Spun bamboo products can also be stained to highlight natural patterns or left in their natural color.
Spun Bamboo can be used as a base for various lacquer finishes and even mother-of-pearl finishes: In certain cases, like crafting large lacquer bowls, spun bamboo is used to achieve the desired bowl shape in a more cost-effective way. These bowls are entirely coated in lacquer, leaving no visible sections of the spun bamboo.
Application of Spun Bamboo
This innovative technique takes bamboo to new heights, allowing it to be shaped into a wide range of exquisite and functional home decoration, kitchenware, lighting, storage box etc. At Rockhill Asia, we continue to cherish and preserve this age-old tradition while offering you an extensive selection of applications for spun bamboo.
THE DIFFERENCE BETWEEN BAMBOO AND SPUN BAMBOO
| Bamboo | Spun Bamboo |
Weight & Portability | Bamboo products tend to be relatively heavier due to the solid nature of the material. This can affect their ease of transport and handling. | Spun bamboo products, being processed and often hollowed, are typically lighter and more portable. This characteristic makes them suitable for a wider range of applications, including lightweight decor and accessories. |
Applications | Bamboo is commonly used in construction, flooring, furniture, and as a raw material for traditional crafts and everyday objects. It retains its natural appearance, with visible nodes and grain patterns. | Spun bamboo is primarily used for decorative and functional purposes, such as home decor, kitchenware, lighting, and artistic creations. Spun bamboo products often have a more polished and refined appearance compared to natural bamboo. |
Cost & Accessibility | Bamboo products are often more affordable and readily available, as bamboo is widely grown and harvested in many regions around the world. | Spun bamboo is primarily used for decorative and functional purposes, such as home decor, kitchenware, lighting, and artistic creations. Spun bamboo products often have a more polished and refined appearance compared to natural bamboo. Spun bamboo products, due to the additional processing and craftsmanship involved, may be comparatively more expensive. |
Production Process | Bamboo is usually harvested, cut into sections, and used directly for various purposes. It can be employed in construction, furniture, and traditional handicrafts without extensive alteration. | The production of spun bamboo is more complicated. It requires soaking, drying, shaping, gluing, and often applying finishes to create decorative and functional items. This process transforms the bamboo into different forms and textures. |
Spun bamboo, with its rich history, meticulous production process, and wide-ranging applications, is a remarkable technique that has captured Vietnamese creativity and showcased the potential of bamboo in a mesmerizing way. Its unique combination of durability, sustainability, and aesthetic appeal continues to make it a sustainable and elegant choice for add a touch of nature to your home.
