A transparent article made of glass ceramic with high surface quality as well as a method producing are provided. The article is suitable for use as a viewing pane. The method includes the steps of: producing a melt with a raw material composition that is suitable for a ceramization; hot shaping a flat substrate made of ceramizable green glass having two oppositely arranged, essentially flat surfaces from the melt; processing of at least one of the surfaces of the substrate with a smoothing fine-treatment process; ceramizing the substrate to produce the article made of glass ceramic.
