*Vitreous enamel is a glass-like coating fused to metal at high temperatures. This process creates a durable, glossy, and corrosion-resistant surface. It's known for its hardness, resistance to scratches and stains, and ability to withstand high heat.
**An anode is a metal rod inside the hot water tank that helps prevent rust. It slowly corrodes over time so the tank stays protected and lasts longer.
