Opening the door

Well, for the most part I’m happy. When I packed the kiln I couldn’t help being alarmed at the amount of black-looking manganese on my vessels. As I said before, you can never be sure of how much you’re applying and leaving on.

But as you can see from the photo, there is white clay still showing, the manganese has become metallic in appearance and (you’ll have to take my word for this) it still has translucency. I’m quite surprised and very relieved. I'll keep experimenting with the thickness of application - variety being the spice and all that.


  1. Hi Jo, well done. I zoomed in on your images and I am surprised to see how much of it actually burned away. The result looks just right to me!

  2. I have to say Jo, it's fairly impressive how well you manage to keep the manganese contained within specific areas. Any time I've used an oxide for decorating, my pots have come out of the final firing revealing bits of dust and fingerprints everywhere! Part of the problem might be the sgraffito obsession I have - not content to leave the painterly line well enough alone etc etc. But then my general clumsiness / lack of finesse could also have a lot to do with it. :p Do you use gum or something in the mix to keep the oxide stable whilst unfired?
