​Heating: Getting the copper plate to the precise temperature over a charcoal forge.
​The Flux: Applying Navsagar (Ammonium Chloride) to help the tin bond.
​Tinning: Melting pure tin (Velli) and rubbing it into a silver-smooth finish.
​Cooling: Quenching the plate in water to set the shine.
​Safety Note: Always ensure you are using 100% pure tin, not lead-based solder, for food surfaces.


Step Action Why it's done
1. Degreasing Scrubbing with acid/lemon Removes grease so the tin can "grip" the metal.
2. Heating Placing over high-heat coal Prepares the copper to melt the tin wire instantly.
3. Fluxing Adding Navsagar powder Cleans the metal chemically and prevents oxidation during heating.
4. Application Rubbing tin with a cotton cloth Spreads the molten tin evenly across the surface.
5. Quenching Dipping in cold water Instantly hardens the tin and gives it a mirror finish.
