Tanahan Sinaran pattern was inspired by the traditional batik motif called ‘lidah api’ (flame); which originally represents the ‘flame’ in one’s soul to get what one desires. Amid these intricate Tanahan patterns, we can also find blank blue spaces called ‘lubang angin’ (vent). Vents like these require a high-level mastery, especially when the batik cloth is about to be dyed in a natural Indigo solution. Batik workers must be careful during this process because the blue color of the vent (which is easily visible on the batik cloth) must appear clean, clear, and even.
