  1. Thanks anyway, oldlady, I thought it may not have been a recent story... but that didn't stop me from Googling a bunch of words you mentioned to see what I could find. Alas, no results. Thanks, tonyp, I was actually able to find some info on him and actually the exact excerpt from that book! He does basically what I was asking about with the addition of other fluxes on a carbon trap shino glaze and includes that recipe. I'll keep exploring his work, thank you for that. https://books.google.com/books?id=th3JZzIFFYQC&pg=PA129&lpg=PA129&dq=ash+glaze+dick+lehman&source=bl&ots=iI4qzExKcE&sig=X-zPhr4ywaFcqOsIjZt0AaB-pfI&hl=en&sa=X&ved=0ahUKEwj1lYq_x8faAhUEk1kKHTqoBhk4ChDoAQg3MAM#v=onepage&q=ash glaze dick lehman&f=false Dick White, yes, this is exactly what I do, thank you for sharing. The spice must flow, indeed! Interesting that it seems to be only shino glaze that people use with wood ash. Is that a spot of iron oxide on your mug as well? What I was initially inquiring about was if there are other glazes that anyone has used with wood ash. Have you? Or is there just something about shino that just works so well? And I also found out that Simon Leach sprays a liquid wood ash mixture through an atomizer onto unglazed surfaces for a "toasty" look. Funny thing is that I met him at a workshop last year and bought one of his mugs with this effect before I even knew what it was. The exact mug I have of his is at 6:07 in this video. https://youtu.be/Co66lGzIMfQ So I did a dozen test tiles of wood ash on various glazes and one on unglazed bisque, hopefully the results will be ready in a few weeks when the next semester begins. I'll keep you all posted. Thanks again for the replies.
  2. Wow, thanks, oldlady. That certainly is dedication and must be nice to have such resources and a controlled environment. I’m working with what I’ve got, I’ll test the glazes available with the mystery ash at hand first before introducing different types of ash. This could be quite an undertaking! Any chance this potter is online or perhaps information on her techniques?
  3. Thanks so much, Joseph, for the clarification... and compliment!
  4. Thank you both for the replies. Yes, Curt, more testing indeed! Was just wondering if anyone has had much experience with this and why results differ greatly with different glazes. It must be something in the chemistry, but I’m not too savvy with that yet so I would need to ask one of the glaze techs or copy the recipe off the barrel, if that would help. And the wood ash bin is a generic mix from someone’s fireplace, I think, which will definitely add some random elements. Test tiles to come... Joseph, very interesting results! So this is your paste on unglazed bisqueware? Your paste is the glaze, correct? That’s quite a texture, thanks for sharing. I’ve not done a wood firing yet, but have seen some other pieces with very heavy ash fall on them, quite similar. I’m looking for something much more subtle, what you saw from me is my school’s shino glaze on porcelain with a sprinkle of wood ash then fired in cone 10 gas reduction. Thanks again, looking forward to more feedback, and of course, more testing.
  5. Hello! New to the site and am curious about the effects of dry wood ash on glazes. I have found a lot of info about wood ash glazes, but not so much about applying dry wood ash onto an already applied and dried (or sometimes sprayed with a little water) glaze. I realize glaze recipes will vary greatly so it may not be very helpful to name any, but I have had great results (in my opinion) with the shino glaze at the pottery school I attend, please see the attached image. I have also tried this on our versions of tenmoku and iron red with results of some fluxing and gold speckling, respectively. So I suppose my question is what is it in shino glaze that reacts that way with the "freckling", for the lack of a more accurate term? (Perhaps this is carbon trapping? I do experiment with a CTC shino as well.) I'd like to experiment with other glazes and colors, but am curious to know if there is a specific ingredient (or more than one) that I should look for to possibly gauge what the results may be with applied dry wood ash. Has anyone tried this on, say, a standard celadon or spodumene glaze, if there are such things? Yes, I am about to do some test tiles, but this will take weeks for results (I am a student so at the mercy of their schedule) so any insight would be greatly appreciated as I could completely avoid any glazes that would have undesirable effect. Thank you so much. Stephen
