Today, the bamboo bowls, bamboo trays, bamboo lamp shade or bamboo baskets are prepared for various purposes, some for daily use and others for some particular use only. The diversity in the size, shape, weaving structure and pattern enables these baskets to have a wide range of applications.
Once the bamboo is harvested, it is necessary to remove all the branches of the culm with the help of a knife. The outer layer of the skin of the culm should be protected very well to avoid scratching them. Cutting the culm into short sections that are easy to carry is an essential step in order to prevent the internodes from cracking or being damaged during transport. This can be done with the help of a handsaw .When cut into short sections, the material can be packed and bundled in order to maintain their good quality for processing.
To separate bamboo culms, it is necessary to place the saw 0.5 cm away from the node and cut parallel to the node. A straight cross-section will enable one to see the actual thickness of the culm wall. For preserving bamboos, it needs to be soaked in water for 15 to 30 days. Soaking makes the culms more subtle and increases their resistance to cracking when dried. Soaking in water does not provide any defense against fungal or pest attacks. However, their resistance to them can be increased by adding boric acid to the water in the pool using a proportion of 1:600. After the soaking process, allow the bamboos to air dry in a shaded area. It is important to remember that the bamboo may crack if the dyeing process is too rapid. Thus, it is necessary to protect the culms from heat and direct sunshine while they are drying.
How to make bamboo bowl, bamboo tray or bamboo basket
Step 1: Cut the bamboo to the required size with the help of a hacksaw/handsaw
Step 2: Remove the skin with knife.
Step 3: Split the bamboo into two halves
Step 4: Split this further to smaller width
Step 5: Split bamboo further for uniform width
Step 6: Split the bamboo parallely between the outer layer and the inner layer
Step 7: Bend the bamboo a little to control the split
Step 8: Keep the thin sliver between the knife and a wooden plank and pull the sliver to clean it further
Step 9: Make sure the splits are uniform in size
Step 10: Selection of splits of the same size
Step 11: Make sure the splits are uniform in its size.
Step 12: Processed splits are stored
In this processing, Dyeing Process and Weaving Techniques are very important steps.
With dyeing process: Identifying the age of bamboo culms by their colour is possible with new and young culms, but is increasingly difficult for older culms. Most of the bamboo when it is young has a distinctive sheen, which is typical for green, yellow and black bamboo varieties. Bamboos with green culms generally have a dark green colour when they are 1 year old, but as the culms age, their colour gradually fades and becomes murky. Thus, for aesthetic beauty, bamboos are dyed into vibrant colours. Dyeing is a simple process that adds colour to any cellulose material like cotton, jute, bamboo, or any other natural fibre. There are two types of dyes, one is the natural dye which is made from the flowers, leaves, barks, minerals etc. while the other is the chemical dye. Since bamboo is a natural and cellulose material and has an off white colour, it can absorb colour well and enhance the beauty of it. Preferably green or non dried bamboos in sliver form are good for better absorption of dyes.
Step 1: Boil the water in a steel tub
Step 2: Select the dyes/ colours required
Step 3: Add salt in the boiled water.
Step 4: Add dyes in the boiled water.
Step 5: Stir it well while it boils.
Step 6: Dip and place the coiled slivers in it.
Step 7: Boil the solution with slivers in it.
Step 8: Remove the slivers from dye after 15-20 min.
Step 9: Wash it properly before using it
Weaving Techniques : Warp and weft are two basic terms used for weaving in general.
Warp is the set of parallel bamboo strips that provide a basis for weaving patterns. In plane bamboo weaving, the warp strips are positioned vertically on the workbench .
The weft is made up of the bamboo strips that are inserted perpendicularly under and over the warp to create a design. In plane bamboo weaving the weft strips are positioned horizontally on the workbench. Color of Woven Bamboo Patterns Weaving dots into patterns is the basic technique for plane bamboo weaving. This weaving technique involves combining 2 colours (light and dark) of bamboo strips along the warp and weft of the bamboo strips.
