  • Custer Feldspar    36.00
  • Quartz   30.00

  • Talc   2.00
  • Bone Ash   2.00

    Notes: This a ∆10 Reduction glaze that will fire to a Creamy White with low gloss to satiny finish. Good over tenmoku, will run if applied too thick over thick tenmoku. As always, test for your ingredient and firing conditions.

      This just make me want to weep in envy. I so miss high reduction firing. I really don’t care what they say about how great midfire electric can be – it never can do this.

        Dee Kat,
        I understand and I know how fortunate I am to be firing ∆10. For me the variations, and degree of chance is what keeps me moving forward. Thanks, Michael

      (but then of course the pieces themselves are the perfect form for the glaze) – sigh again.

    3. Great surface, thanks for sharing the recipe so I do some experimenting! Did the red tones at the lip come from dipping the pots in Temmoku first? Was Temmoku just glazed at the lip or over the entire pot? I’ve been trying to get similar colors on the rims of my pots using Red Iron Oxide stain…

      Joel,
      The pieces were first glazed overall with the tenmoku and then the nuka. The reddish lips on the pieces is due to the slight downward movement of the tenmoku when firing, causing the the glaze to “break” off the edges and textures. Hope this answers your question. Let me know if not.

      Beautiful – both the glaze and the forms! Thanks for sharing the recipe. It will be at least 6 – 9 months before I get my studio up and running. Planning to stay with ∆10 reduction firing and love tenmoku combined with another glaze — so will file away for future use!

      Thanks Michael. Beautiful forms and glazing. Could you share the tenmoku glaze recipe. I have the opportunity to fire in a friend’s gas kiln but only have a cone 9 tenmoku recipe.

      Is the wood ash a sub for rice hull ash?

        Hi Marcos, Yeah the wood ash and the increased silica content of this glaze subs for the traditional rice hull ash.

      The nuka glaze recipe is in a book called Hamada Potter published about twenty years ago.. I used to be able to buy rice hull ash at an auto parts store as ” clean sweep” sweeping compound.. It works great in a Nuka glaze.. The basic glaze is equal parts feldspar, wood ash and rice hull ash. Rice hull ash is about 90 plus percent silica.

    11. That’s a great tip, Jay. I hadn’t heard that, though I think I have the Hamada Potter book. And the Phil Rogers book. I’ve just started using this recipe here at my studio and I love it.
