A Blue, Blue Glass of Home!

Hello Readers and Bloggers,
Today's word is a word to describe your grandma's fine china. Some bowls and cups have a nice, blue pattern on it. This is called *drumroll* smalt ! It is made of cobolt oxide and the deep blue colour is from the oxidization.
In a sentence:
The plate had a  smalt  pattern on it.

Well, bye everyone!
