Aranmula Kannadi (Metal Mirror) Craft
A mirror made of metal, not glass — reflecting from its very surface, with no ghost image.
The Aranmula kannadi is a mirror cast from a polished metal alloy rather than silvered glass. Because the reflecting layer is the front surface of the metal itself, the image has no secondary reflection, no parallax and no ghosting — the viewer sees a single, exact reflection. The mirrors are set in ornate cast-brass frames, made in sizes from a keychain trinket to a full-length stand, and are considered auspicious in Kerala: they form part of the ashtamangalyam, the eight lucky objects of ceremony, and are given at weddings and used in temple ritual. The exact composition of the alloy is a closely guarded family secret.

GI Status
Aranmula Kannadi is a registered GI of Kerala, among the earliest Indian crafts registered
Process Steps
Preparing the mould
Two halves of a mould are formed from fine local clay mixed with charred coconut husk, dried and lightly fired.
Alloying the metal
Copper and an unusually high proportion of tin are melted together to the secret Aranmula composition.
Casting the disc
The molten alloy is poured into the pre-heated mould and left to solidify into a flat disc.
Truing and grinding
The cast disc is ground flat against stone and emery to remove the casting skin, pits and warping.
Rough polishing
The face is worked against progressively finer abrasive surfaces to bring up an even, dull shine.
Fine hand polishing
Over many days the surface is polished by hand with cloth or leaf pads and fine powder until it becomes truly mirror-bright.
Framing
The finished mirror is riveted or set into a cast, chased and polished brass frame, often with a handle or stand.
Technique Glossary
Speculum metal
A brittle, highly reflective bronze with a high tin content, historically used for telescope mirrors.

Vishwakarma / Sthapathi
The hereditary community of metal- and temple-craftsmen who hold the Aranmula tradition.
Ashtamangalyam
The set of eight auspicious objects used in Kerala ceremonies, of which the metal mirror is one.
Investment mould
The fired clay-and-husk mould into which the alloy is poured.
Lapping
Rubbing a surface flat and smooth against a hard plate charged with abrasive.
GI hologram
The tamper-evident sticker that certifies a mirror as genuine Aranmula ware.
A Craft Through Time
Legendary origin
The temple commission
Craftsmen brought to work on the Aranmula Parthasarathy temple are said to have discovered the reflective alloy while casting temple items.
Pre-modern
A ritual object
The metal mirror becomes part of Kerala's ashtamangalyam and a standard auspicious gift.
19th–20th century
A single-village craft
The alloy and polishing method remain confined to a few Aranmula families, making the mirror rare and prized.
2004–2005
Geographical Indication
Aranmula Kannadi receives a GI tag, among the first Indian crafts to be registered.
Present
A few workshops remain
Only a small number of family units still make the mirrors, and genuine pieces carry a GI hologram.
Did You Know?
The alloy's exact recipe is known to only a handful of families in one village and has never been published; every attempt to make an equivalent mirror elsewhere has failed to match the Aranmula finish.
