What is Kansa Bronze
What is Kansa Bronze?
Kansa is a specific bronze alloy composed of 78% copper and 22% tin—a higher tin content than average bronze (typically 85:15). This precise ratio has been used for over 3000 years in culinary traditions and forms the foundation of Eaglador's heavy gauge cookware.
How Kansa Differs from Regular Bronze
In the West, searches for bronze cookware often lead to articles cautioning against its use in the kitchen. These observations generally refer to standard bronze alloys, which typically contain a lower tin content — often only 10–15%. Such compositions can react more readily with acidic ingredients, giving rise to understandable concerns about leaching and everyday suitability.
Kansa bronze is fundamentally different. Its significantly higher tin content of 22% creates a more stable alloy, forming a natural protective barrier both on the surface and within the metal itself. This inherent layer gently shields the copper and prevents harmful leaching — even when preparing dishes with tomatoes, citrus, vinegar, or wine.
The Power of the 78:22 Ratio
Pure copper conducts heat superbly, yet its softness makes it difficult to cast into thick, durable forms. Traditional copper cookware is therefore typically spun rather than cast and requires an inner lining of tin or stainless steel.
The addition of 22% tin transforms the alloy. It improves fluidity during casting, increases hardness, and forms stable intermetallic compounds. This precise balance allows the creation of substantial, heavy-gauge pieces through traditional lost-wax methods — and enables Kansa bronze to remain completely unlined and uncoated while staying non-reactive and safe for daily food use.
It is this ratio that makes true luxury heavy-gauge Kansa bronze cookware both possible and practical in the modern kitchen.
Uncoated and PFAS-Free
The elevated tin content in Kansa bronze creates a stable natural barrier that allows our cookware to remain completely uncoated and 100% PFAS-free. No chemical linings or artificial non-stick coatings are ever needed.
This inherent stability, combined with traditional lost-wax casting, delivers true heavy-gauge luxury cookware that is non-reactive and safe for everyday use — even with acidic ingredients.
Alkaline by Nature
Kansa bronze possesses a gentle alkaline nature rooted in centuries of Ayurvedic tradition. It subtly harmonises with ingredients during cooking, helping to balance acidity while preserving the true flavours and nutrients of each dish. This quality helps to support smoother digestion and gut health.
This refined alkaline character is part of what sets Kansa apart — gently transforming everyday meals into something more balanced and harmonious.
Patina Development
With regular use, Kansa develops a beautiful, natural patina — a thin, self-renewing oxide layer on the surface. This patina is not a flaw; it improves over time, enhancing the non-stick properties and adding unique character to each piece. Like well-seasoned cast iron, the patina makes the cookware perform better with age and becomes part of its heirloom story.
