Pure 99.6% virgin copper is an extremely soft, malleable metal. It is physically impossible to machine a moving mechanical lever valve out of soft copper without the friction grinding the metal down and causing leaks. As disclosed in our Material Transparency Charter, our dispensers use heavy-duty food-grade 304 stainless steel or solid brass spigots fitted with dual food-grade silicone washers for a lifetime drip-free seal, while your water rests inside the 100% unlined 99.6% pure copper tank.

That natural darkening (patina) is chemical proof that your dispenser is 100% raw, unlined pure copper! Pure copper contains zero iron and cannot rust. When bare copper meets water and oxygen, it naturally forms dark copper oxide spots. To restore the bright copper shine in 60 seconds, rub the interior walls with half a lemon dipped in 1–2 tablespoons of salt, swirl with warm water, and rinse 3 times with clean water.

Traditional Ayurvedic copper Matka dispensers are single-wall metal vessels (not double-wall vacuum-insulated thermoses). If you fill the tank with cold or chilled water in a warm room, natural condensation droplets will form on the outside walls and pool at the base. External condensation is normal physics—not a leak! We recommend using room-temperature water for Ayurvedic Tamra Jal and placing your dispenser on a stand, tray, or coaster.

No — store plain, room-temperature or cool drinking water only! Because the interior is 100% raw, unlacquered copper, acidic ingredients (lemon slices, citrus, cucumber/fruit infusions, vinegar, tea, coffee, carbonated water) react rapidly with bare copper and cause excessive copper ionization and metallic taste. Use lemon juice strictly for 60-second cleaning, then rinse out completely.

Never — strictly hand wash only. High heat and caustic dishwasher detergent tablets permanently strip the exterior finish and heavily oxidize artisanal copper, voiding warranty and return eligibility.
