1. Gathering of Rubber Leaves Fresh and healthy rubber leaves are gathered from rubber trees. Each leaflet has an area of about 3*7 inches. Being small in size, it can be processed into a single piece of product only, but if various sizes of leaves, ie 1*2 inches the smallest up to 5*12 inches the largest, are required all kinds of product can be made of. The most appropriate leaves should, for the best result, come from a budwood nursery. It is, therefore, necessary to establish a budwood nursery, which would take at least one year.
2. Boiling Leaves in an Alkaline Solution Rubber leaves under step one are weighed out for two kgs. An alkaline solution is proposed by dissolving two bars of soap (sunlight) in 20 litres of water. The rubber leaves and the alkaline solution are placed in a container and place the container on fire until boiling for 90-120 minutes, By that time all the leave skin and cellulose have cecome thoroughly softened.
3. Scraping off Skin and Cellulose Alll the softened leaves are scraped off on the surface by means of a toothbrush until only a leaf-vein akeleton exists. Wash the leaf-vein skeleton throughly and dry in the sun. It takes about two hours for the leaf-vein skeleton to dry completely. When dry the leaf-vein skeleton will turn brown and is considered unsuitable for processing into any product except after dyeing.
4. Dyeing of Leaf-vein Skeleton The leaf-vein skeleton is then whitewashed, so that it will be colourful when dyed. To whitewash the leaf-vein skeleton a detergent called "Hyter" in a liquid form is recommended. Hyter is available on the market and easy to use. Hyter is first diluted with water at the appropriate proportion of one part of Hyter to six parts of water. Then submerge the leaf-vein skeleton in the liquid mixture for about four hours. The leaf-vein skeleton is now whitewashed and suffers no damage. Then have the whitewashed leaf-vein skaleton washed again and dried. The pale, clean leaf-vein skeleton is now ready for dyeing or colour spraying.
5. Creating of Flowers and Other Products The creation of flowers from the leaf-vein skeleton of rubber is a technique plus personal experience, aptitude and the application in which the leaf-vein skeleton is manipulated to fit according to the size of flowers and products. A yuong leaf of rubber has a softer leaf-vein skeleton than a very oil on, which is suitable for making a petal of flowers, while the very oil leaf-vein skeleton is thick, hard and stiff, there fore, suitable for making a leaf or a sepal or other products. An assistance of colour spraying technique would make a flower colourful and looks similar to the natural one. Besides, the colour of the flower or the product would last long upto three years in the shade. A study on costs of fabrication of flowers from rubber leaves, which was based on cost, income, profit and loss in the production of 30 products at Yala Rubber Experiment Station was found that the main cost of the production was a labour cost, investment on materials was not large.
