Almost everyone who comes here ends up buying batik, and almost nobody knows what they are buying. In the same market, and sometimes on the same stall, pieces that took months of work sit beside industrial fabrics imitating the design.
The price difference can be a hundred to one, and it is not visible from the pretty side. It is visible in two seconds if you know what to do with the cloth.
01 It is drawn in wax, not in dye

The principle is the opposite of what it looks like. The design is not painted: what is painted is everything that will not be dyed. Hot wax is applied to the cloth following the pattern, left to cool and acts as a waterproof barrier.
Then the cloth goes into the dye. When it comes out, the fabric has taken colour everywhere except under the wax, which is removed with boiling water. What remains is a negative design, made of absences.
And there is the slow part: for a second colour you have to wax, dye and boil again, and so on. Every colour in the cloth you are looking at is a complete cycle, and a complex piece can take weeks or months.
You do not draw what you see: you draw what has to be protected. The dye does the rest.
02 The canting and the copper stamp

There are two legitimate ways to apply the wax. The first is by hand, with a canting: a copper reservoir with a very fine spout and a bamboo handle, filled with hot wax and used like a pen. With that you draw line by line.
The second is with a copper stamp, a plate on which the design is formed of metal strips on edge. It is dipped in wax and pressed onto the cloth, and each press leaves a module. It is a 19th-century innovation meant to produce faster.
Both count as batik, and both are recognised as intangible heritage. What does not count is cloth with the design machine-printed, which imitates the look without ever using wax.
03 Why the back gives it away
Here is the practical test, and it always works. Hot wax does not stay on the surface: it soaks the weave and comes out the other side. That is why the resist protects the whole cloth, not just the face.
The consequence is that on a genuine batik the back shows the same design, with very similar sharpness. On the best pieces it is hard to decide which side is the front, and in traditional workshops both faces are waxed precisely for that reason.
Printed fabric cannot do that. The ink sits on one side and, if the weave is fine, shows through dull and blurred. Turn the cloth over, hold the back to the light and you will have your answer before you ask the price.
04 This city's white

Batiks are classified by the region they come from, and the first division is between those of the island's interior and those of the coast. The inland ones are the oldest tradition and use earth colours: black, indigo, brown and a dark yellow drawn from a tree.
Within that family, this city and its neighbour are the two references, and they are told apart by the ground. Batik from here is typically made on a white ground; that of the city next door, on that yellowish brown ground.
Coastal batiks are another matter: brighter colours and motifs arrived by sea trade, with European flower bouquets, Chinese birds and Persian peacocks. Knowing this lets you look at a cloth and place it on a map.
05 A cloth worn on Fridays
On 2 October 2009 UNESCO inscribed hand-drawn and stamp-printed batik on its intangible heritage list. Since then that date has been National Batik Day in the country.
The practical effect was immediate and still holds: people were encouraged to wear batik on Fridays, and since then public offices and private companies have adopted it as a weekly habit.
So if you arrive on a Friday, you will see the city dressed differently. This is not folklore for the visitor: it is work clothing, and it is worth understanding it that way before taking out a camera in an office or a bank.
06 What to look for when buying
First, the back, which is the test you now know. Second, the irregularities: on a hand-drawn piece the lines waver slightly and the motifs are not exactly identical to one another. That lack of perfection is the craft's signature.
Third, the repeats. If the design repeats in perfectly identical modules but the back is well dyed, you are probably looking at a stamped batik: it is not the same as hand-drawn, it costs considerably less and it is still batik.
And fourth, the smell and the feel. A freshly finished cloth sometimes keeps a trace of the process, and fabric waxed and boiled hangs differently from cotton printed by the roll. With two or three pieces in your hands, the difference stops being theoretical.
