Overview
This is a 'Cap' (pronounced 'chop'), a hand-forged copper tool used by master batik artisans to apply intricate wax patterns to fabric.
Story
In the mid-19th century, the invention of these copper stamps revolutionized the Indonesian textile industry, allowing artisans to create complex patterns much faster than the traditional hand-drawn 'tulis' method.
Maker / Origin
These were rarely signed by an individual artist; instead, they were the product of specialized metalworking guilds in cities like Pekalongan or Solo.
Condition & Value
The stamp shows significant oxidation and 'verdigris' (green patina), which is expected for a tool used with hot wax and dyes. There appears to be some minor bending in the outer copper strips, but the overall structural integrity of the pattern remains excellent. The presence of old wax residue adds to its authenticity.

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.
