Where is there any irony or descriptive language in Great Expectations by Charles Dickens?

Dickens is notably one of the best writers of description,
so I would encourage you to open to most any page of the book to find some, besides you
are asking two questions in one and that is not allowed. Thus, I will address this issue
of irony.

Irony is a surprising twist of events. This
occurs regularly throughout the story.

• It is
  ironic that the man Pip meets on the marshes has a great iron on his leg as Pip is a
  child living in a blacksmith's forge. (Chapters
  1-3)


• Irony is a convict that is so rich that he may
  anonymously fund Pip's attempt to become a gentleman. (Chapter
  40)


• Irony is high society Estella having parents of much
  less than noble social class in Magwitch and Molly. (Chapter
  56)


• It is ironic that Pip's challenger in the pale young
  gentleman becomes his best friend Herbert Pocket later in the story. (Chapter 22)
