Brass (Pital) has been the metal of choice for Indian cooking for centuries. However, to make it safe for acidic foods like curries, yogurt, or tamarind-based dishes, it requires a protective layer. This ancient technique is called Kalai (tin-lining), a craft we have perfected in our workshop. Our Kalai process uses 100% high-purity, lead-free tin, exceeding FDA food-safety standards.
What is Kalai?
Kalai is the process of coating the inner surface of brass utensils with pure tin (Vanga). This creates a non-reactive barrier between the food and the brass. Without this lining, acidic foods can react with copper in the brass, turning the food bitter and potentially harmful.

Why is it Vital for Your Kitchen?
- Safety: Prevents chemical reactions that can cause food poisoning.
- Taste: Preserves the authentic flavor of your spices and ingredients.
- Conductivity: Tin is an excellent conductor, ensuring the vessel retains the superior heat distribution of brass.
Maintaining Your Kalai
A good Kalai coating lasts for months or even years depending on usage. Use soft sponges for cleaning and avoid scratching the lining with sharp metal ladles. When the gold of the brass starts peeking through the silver tin, it's time for re-tinning—a service traditionally available in most Indian cities.
Because safety is our priority, all Copper Mart cookware is hand-tinned by heritage artisans. Explore our Tin-Lined Copper Handis to see the craftsmanship in action.
