​🛠 The Full "Kalai" Process|Step-by-Step|HINDI URDU| ​1. The Deep Clean (Safaai) ​The plate is first rubbed with a mixture of caustic soda or dilute acid and sand to remove years of oxidation and grease. In the video, show the "before" (dull brown) turning into "bright pink" copper. ​2. The Fire Pit (Bhatti) ​The artisan places the plate over a coal-fired bellows furnace. The copper must reach a specific temperature—not too hot to melt, but hot enough to liquefy tin instantly. ​3. The Flux (Naushadar) ​The "magic powder" used is Ammonium Chloride (called Naushadar in India). When it hits the hot plate, it creates a thick white smoke. This cleans the surface chemically so the tin sticks perfectly. ​4. The Tinning (Ranga Lagana) ​A small piece of pure Tin (Ranga) is rubbed onto the hot copper. It melts like butter. Using a cotton rag or a piece of cloth, the artisan quickly and skillfully wipes the molten tin across the entire surface. ​5. The Cold Plunge (Thanda Karna) ​The plate is immediately dipped into cold water. You’ll hear a loud hissing sound—this sets the tin and gives it that brilliant, mirror-like silver finish.
