Terne plate

Terne plate is a special type of metal that was used a long time ago to make things like roofs, gutters, and even toys! It's made by taking a really thin sheet of iron and coating it with a mixture of lead and tin. This makes the metal stronger, more durable, and resistant to rust and corrosion.

The reason people use terne plate for roofs and gutters is because it's really good at keeping rainwater out. The lead and tin coating makes the metal water-tight, so rain can't come through and make your house all wet inside. Plus, because it's so durable, it lasts a really long time without needing to be replaced or fixed.

Even though terne plate isn't used as much anymore, it's still a really important part of history and an interesting thing to learn about!
