A kansa glass is a traditional drinking vessel made of kansa, an alloy of copper and tin, known for its health benefits. It has a warm, rustic appearance with a slightly grayish-brown hue. Kansa is believed to have antimicrobial properties that help purify liquids. The glass is often used in Ayurvedic practices and is valued for its ability to enhance taste and promote digestion. Regular cleaning is required to maintain its shine and prevent tarnishing.
