Country Girl Posted April 5, 2021 Report Share Posted April 5, 2021 I fired some mugs in a celadon glaze. The 1 mug on the bottom shelf came out a darker green than the ones on the top shelf. Can anyone tell me why this happened? Thank you Link to comment Share on other sites More sharing options...

Callie Beller Diesel Posted April 5, 2021 Report Share Posted April 5, 2021 Can you give us a little more information? What celadon recipe was it? Cone 10 or commercial cone 6? Gas or electric? What kind of clay? Was temperature confirmed by cone packs, as Chilly mentioned? Link to comment Share on other sites More sharing options...
