What does NABL certified mean for cookware?

NABL (National Accreditation Board for Testing and Calibration Laboratories) is India's highest standard for testing laboratories. House of Dhatu uses XRF (X-ray fluorescence) testing to verify the exact metal composition of every production batch. Customers receive a certificate of composition with their order, confirming the purity of the metal.

How does the House of Dhatu metal buyback programme work?

Like a jeweller who quotes the gold rate and repurchases gold, House of Dhatu offers to purchase any of its pieces at the current live market rate for the metal. There is no time limit — this applies at any point in the future. Contact us for a quote and we will respond with the current rate for brass, copper, or kansa.

How do I restore the shine on a brass or copper vessel?

Mix lemon juice and salt into a paste, apply to the surface, rub gently, then rinse with warm water and dry immediately. Tamarind paste works equally well. The metal will recover its original lustre. This can be repeated as often as desired — there is no coating to damage.

Does pure brass or copper cookware require special care?

Avoid dishwashers, abrasive cleaners, and prolonged soaking in water. Wash with warm water and a soft cloth, then dry immediately. Store in a dry place. A natural patina will develop over years of use — this is authentic and desirable. Polish with lemon and salt to restore shine whenever preferred.

Honest Pricing

Why pure metal is the smarter buy

Most cookware costs less upfront because it is designed to be replaced. Pure metal is priced honestly, because it is built to last and hold its value.

Lifespan

Built to outlast every kitchen it enters

Non-stick coatings degrade in 1–2 years. Ceramic chips. Stainless steel lasts a decade if well maintained. Pure brass, copper, and kansa have no coating to fail. The metal itself is the surface. Buy once. Pass it on.

Value Retention

The only cookware your jeweller would understand

When a non-stick pan wears out, it's landfill. Pure metal holds its material value indefinitely. We offer buyback at the live market rate, just like a jeweller buys back gold. Your cookware is an asset, not an expense.

Common Questions

Is it safe to cook in brass?

Brass is safe for most cooking and serving. For acidic foods (tamarind, tomatoes, citrus), use pieces with a tin lining (kalai). Our product descriptions specify whether kalai is included. Copper and brass have been used in Indian kitchens for thousands of years.

What does NABL certified mean?

NABL is India's highest standard for testing labs. We use XRF testing to verify the exact metal composition of every batch. You receive a certificate of composition with your order.

How does the metal buyback work?

Like a jeweller quoting the gold rate and buying it back, we offer to purchase any House of Dhatu piece at the current market rate of the metal. Contact us and we'll quote you the live rate. No time limit — this applies whenever you want.

How do I restore the shine?

Rub with a paste of lemon juice and salt, or use tamarind paste. Rinse with warm water and dry immediately. The brass will glow like new.
