The usage of cap, as opposed to canting, to apply the wax has reduced the amount of time to make a cloth.
Today, batik quality is defined by cap or tulis, the second meaning hand-drawn designs which use a canting, or kombinasi, a combination of the two techniques.
Traditional colors for Central Javanese batik were made from natural ingredients and consisted primarily of beige, blue, brown and black.
The oldest color that was used in traditional batik making was blue. The color was made from the leaves of the Indigo plant. The leaves were mixed with molasses sugar and lime and left to stand overnight. Sometimes sap from the Tinggi tree was added to act as a fixing agent. Lighter blue was achieved by leaving the cloth in the dye bath for short periods of time. For darker colors, the cloth would be left in the dye bath for days and may have been submerged up to 8 – 10 times a day.
In traditional batik, the second color applied was a brown color called soga. The color could range from light yellow to a dark brown. The dye came from the bark of the Soga tree. Another color that was traditionally used was a dark red color called mengkuda. This dye was created from the leaves of the Morinda Citrifolia.
The final hue depended on how long the cloth was soaked in the dye bath and how often it was dipped. Skilled artisans can create many variations of these traditional colors. Aside from blue, green would be achieved by mixing blue with yellow; purple was obtained by mixing blue and red. The soga brown color mixed with indigo would produce a dark blue-black color.
The outline of the pattern is blocked out onto the cloth, traditionally with charcoal or graphite. Traditional batik designs utilize patterns handed down over the generations. It is very seldom that an artisan is so skilled that he can work from memory and would not need to draw an outline of the pattern before applying the wax. Often designs are traced from stencils or patterns called pola. Another method of tracing a pattern onto a cloth is by laying the cloth on a glass table that is illuminated from below which casts a shadow of the pattern onto the cloth. The shadow is then traced with a pencil. In large batik factories today, men usually are in charge of drawing the patterns onto the cloth.
Once the design is drawn out onto the cloth it is then ready to be waxed. Wax is applied to the cloth over the areas of the design that the artisan wishes to remain the original color of the cloth. Normally this is white or cream.
Female workers sit on a low stool or on a mat to apply the wax with a canting. The fabric that they are working on is draped over light bamboo frames called gawangan to allow the freshly applied wax to cool and harden. The wax is heated in the wajan until it is of the desired consistency. The artisan then dips her canting into the wax to fill the bowl of the canting.
Artisans use the wax to retrace the pencil outline on the fabric. A small drop cloth is kept on the woman. s lap to protect her from hot dripping wax. The stem of the canting is held with the right hand in a horizontal position to prevent any accidental spillage, which greatly reduces the value of the final cloth. The left hand is placed behind the fabric for support. The spout does not touch the fabric, but it held just above the area the artisan is working on. To ensure the pattern is well defined, batik is waxed on both sides. True tulis batik is reversible, as the pattern should be identical on both sides.
The most experienced artisans normally do first waxings. Filling in of large areas may be entrusted to less experienced artisans. Mistakes are very difficult to correct. If wax is accidentally spilt on the cloth, the artisan will try to remove the unwanted wax by sponging it with hot water. Then a heated iron rod with a curved end is used to try and lift off the remaining wax. Spilled wax can never be completely removed so it is imperative that the artisans are very careful.
If the cap method is utilized, this procedure is normally done by men. The cap are dipped into melted wax. Just
