Copper Purity & Authenticity Guide
How to verify 100% pure Ayurvedic copper through simple home tests and laboratory metallurgical standards.
Simple Home Tests to Verify Authentic Copper
Authentic copper possesses distinct physical and chemical characteristics that cannot be mimicked by copper-plated steel or impure alloys:
Test 01
The Lemon-Salt Oxidation Test
Pure copper oxidizes naturally into dark brown patina when exposed to air. Rubbing a slice of lemon with rock salt restores brilliant pinkish-gold gleam in 15 seconds.
Test 02
The Non-Magnetic Test
Pure elemental copper is completely non-magnetic. A strong kitchen magnet will not stick to or pull on authentic copper vessels.
Test 03
Warm Tone & Soft Resonance
Pure copper produces a deep, mellow, soft sound when gently tapped, unlike the sharp metallic ring of steel or iron.
