What is Oscar Wilde's "Blue China"?

"I find it harder and harder every day to live up to my blue china." What did Oscar Wilde mean by Blue China?? Did he use it to refer to his friends who betrayed him??if yes,why "blue china"?

Solution 1:

As an aesthete, Wilde decorated his rooms at Magdalen College with many objets d'art, including blue china (porcelain).

The famous "I find it harder and harder every day to live up to my blue china" I think refers to the perfect beauty and unsurpassable aesthetics of the china that we as humans could never hope to attain.

Wilde is saying that an object of beauty ("blue china") can be something to measure one's life against.

There's some information about it on Wikipedia.

Blue china can indeed look amazing:
