Tanjore painting (Thanjavur) emerged in 16th-century Maratha-ruled South India. The signature look — embossed gold-foil over gesso, semi-precious stone inlay, hyper-detailed figures of Hindu deities — is unmistakable.

Authenticating a Tanjore

• Gold leaf: real 22k gold leaf has a soft, warm sheen — not the cold yellow of cheap foil.
• Gesso work: lift-up patterns made with chalk paste. Tap with your fingernail — real gesso has depth, not a flat sticker feel.
• Stones: traditionally Jaipur kundans. Plastic 'stones' are an immediate red flag.
• Wood backing: jackfruit or teak plywood. Plywood that warps in a year isn't authentic.

• Hang away from direct sunlight. Gold leaf darkens with UV exposure.
• Humidity below 60%. Dehumidify in monsoon if you live in coastal cities.
• Dust with a soft sable brush — never a damp cloth.
• Re-glaze the protective coating every 8-10 years with a conservator.
