Okay kiddo, have you ever seen a really fancy piece of furniture or decoration that has a lot of gold or bronze color on it? That's called ormolu, which is a special kind of decoration made from a mix of metals like bronze, gold, and even silver.
Basically, it's a way of making something look very fancy and expensive without actually using solid gold or bronze. They melt down the metals together and pour it into molds to make shapes like flowers or animals, then attach it to a piece of furniture or use it as a decoration.
Ormolu has been used for hundreds of years to make things look more luxurious and fancy. It's kind of like putting glitter on something - it just makes it look more special and glamorous.
