Older test tiles for different soda fired glazes.

I am quite happy with the glazes I use. Of course, if you know any artist, anything we might be happy with tends to change quite frequently and dramatically. But for now these glazes are very satisfactory to me and their visual quality seems long-lived.

Keep in mind I fire in a hot cone 10 reduction atmosphere with iron-bearing clay…usually with lots of grog.
American Shino:
50 Nepheline Syenite
25 Ball Clay
25 Spodumene
0-2 Soda Ash
I formulated this glaze by studying quite a few American potters’ shino recipes. I began by testing many recipes and noting both likes and dislikes of each glaze test. Noticing patterns, it became obvious to me that I really enjoyed a shino that included the ingredient Spodumene. BINGO! I also enjoy simple recipes with few ingredients the most, so the recipe came quite easily after the testing. Enjoy!
Notes:
  • This is a cone 10 glaze that likes a hot firing.
  • What I love about it: it fires from creamy white to dark orange, thick to thin; it pinholes beautifully where you trim; it has a wonderful feel; it doesn’t crawl.
  • What I am unsatisfied with: It crazes a bit too much; it is too shiny; it doesn’t crawl :).
American Shino – One of my favorite bowls.

 

American Shino – The variety of colors with this glaze are fantastic!
Creamy whites, dark oranges. Mmmmm!

 

American Shino – Notice the pinholes on the trimmed foot! Wowza!

 

American Shino – Finger swipes. Mountains and valleys.

 

American Shino – More sexy pinholes!

Yellow Matte:

50 Nepheline Syenite
25 Epk
25 Whiting
As you can see, this is another simple recipe. It came from my love of Warren Mackenzie’s Mackenzie Grey Matte that is so prevalent. I simply substituted ingredients and it came out so very differently it is another glaze entirely.
Notes:
  • This is a cone 10 reduction glaze
  • What I love about it: The matte quality in this glaze is fantastic (if it works); the yellow color is also a very gorgeous soft earthy yellow; it fades to a black rocky color when thin.
  • What I hate about it: The glaze settles VERY fast; the yellow color comes only if you’re lucky; it tends to have a greenish hue; if you dip too thin it comes out a washed out stony black color that is very rough to the touch (but I sand it down and it is actually really nice after being sanded!); it is inconsistent as of yet…needs some tweaking.
Yellow Matte: The variety of colors with this cup are wonderful, albeit
difficult to see in this lighting.
Yellow Matte – The underside of the cup. I love feet 🙂
Yellow Matte – Notice how much drier this cup is compared to the top one.
I had to sand this cup heavily inside and out to make it good for use.
Mackenzie Grey:
50 Custer Feldspar
25 Whiting
25 EPK Kaolin
This is Warren Mackenzie’s famous matte grey glaze. An excellent, simple, and beautiful recipe that I formulated my Matte Yellow glaze from.
Notes:
  • Cone 10 reduction glaze
  • What I love about it: The grey is variable from thick to thin, going from brown to red to greenish to grey and sometimes even a wonderful sea blue; it’s a beautiful matte glaze that feels wonderful too; great for pouring over large pieces.
  • What I don’t like about it: Not very durable–metal marks from silverware, acidic drinks left inside overnight will etch the glaze; crazes
Mackenzie Grey – A thicker application with finger marks.
Mackenzie Grey – Very thinly applied with finger dipping marks. Notice the reds coming through!
Mackenzie Grey – This jar shows the glaze off really well. It has blues, greys, reds, browns and greens!
Temmoku:
48.38 Custer Feldspar
20.14 Flint/Silica
11.64 Whiting
8.05 Red Iron Oxide
5.40 EPK Kaolin
2.24 Barium Carbonate
2.24 Zinc Oxide
This is a Bethel University classroom glaze graciously given to me by professor Kirk Freeman. Thanks Kirk! This temmoku is shiny and true black, and breaks to a beautiful coppery red/brown on edges and around handles.
Notes:
  • This is a cone 10 reduction glaze.
  • I dip my mugs one time only but for 20 seconds each. This ensures a nice thick coating that is not globby and gives a fantastic color.
  • What I love: The temmoku has a beautiful black color and the copper breaks are AMAZING; it doesn’t run when you dip for 20 seconds, even at cone 10.5; it looks amazing with coffee inside a temmoku glazed mug.
  • What I don’t like: the dried raw glaze can easily transfer from your fingertips to a white glazed pot without you noticing, and then you have red fingerprints on white pieces. But that’s about it!
Temmoku – Notice the wonderful coppery reds? Mmmmmm
Temmoku – Notice it outlines my signature stamp VERY well.
Temmoku – The blacks are deep with this glaze, my young padawan.

Chun Clear:

42.50 Custer Feldspar
26.55 Flint
8.85 Gerstley Borate
8.85 Dolomite
4.45 Barium Carbonate
2.65 Tin Oxide
1.75 EPK Kaolin
1.75 Zinc Oxide
This is a Bethel University class glaze graciously given to me by Kirk Freeman. Thanks Kirk!
A clear glaze with a slight blueish hue. Beautiful on porcelain and stoneware, but very different on both.
Notes:
  • Cone 10 glaze reduction
  • What I like: a beautiful glaze I love for porcelain mostly but can be really great with iron-rich clays too; crazes beautifully; very subtle and a lifetime of visual pleasure.
  • What I don’t like: sometimes it scums a little bit on the inside of cups or bowls.
Chun Clear – Over a buff stoneware, works beautifully
with light surface decoration, in this case combing.
Chun Clear – A slightly oxidized firing, this chun turned a
milky white on the right side. Over fireclay stoneware.
Chun Clear – Over a buff stoneware, notice the fine crazing.

  1. Hey Phil, we had a batch of American Shino that I was told needed to be remixed. I gave it a go anyways and I really liked the results. Rather than coming out so orange, it was mostly a creamy white with slight orange breaks on the edges, pinholes, and it crazed. On some of the pieces, it carbon trapped quite nicely. Do you know what would have caused this so I can use it to my advantage again? (Too thick, substituting ingredients? I’ve noticed the American Shino turning into Carbon Trap, the Carbon Trap getting a Davis Shino look, and Davis Shino going black and gold.)

    1. Hey Chris!
      I am glad you like American Shino! It sounds like you applied the glaze quite thick, which would give it that creamy white color.
      As for the carbon trapping, generally that is helped along with soda ash. If you add 5% soda ash to a test batch you might get more carbon trapping. However, please don’t mess with the 5 gallon class glaze, mix your own tests and whatnot. Thanks!

      I hope this helps!

  2. Hi Phil,

    Thanks for sharing your recipes! My experience since I started throwing pottery a bit over a year ago has been mainly cone 6 stoneware, but I was recently offered the opportunity to help with an anagama firing and include some pieces. I came across your American Shino recipe in my search for cone 10 glazes and mixed up a batch to try on a few porcelain pieces . We’re loading the kiln today and tomorrow with firing for the next week. I’m curious/excited to see how it turns out in the anagama!

    1. Hello Jay,
      Thanks for saying hi! I am glad you happened upon the American Shino recipe! It’s my favorite, but I have never had the great opportunity to fire in a wood kiln with it. I hope the results are as favorable as they have been for me! I would love to see the results when they are finished, so please respond back if you have time!

  3. Phil,

    My apologies for not responding back much sooner. I had to wait about 6 months after the wood firing to get my pieces since it is a good 8-10 hour drive away and I wasn’t going to stay out of town an extra week waiting for the kiln to cool down after the firing.

    Anyway, I didn’t get any of the orange/brown coming through on my pieces in the anagama. They were all porcelain and I dipped it on relatively thick. It was creamy white but that provided a great backdrop for the fly ash, etc that settled on them. The best of them are pretty nice! I can’t post photos in the comments or I’d share the results here.

    I’ve since met a new potter friend who lives much closer and fires with wood as well so I’m excited to join him in some upcoming firings. Thanks!

  4. Hi Phil

    Great post. I always appreciate it when potters share recipes. I was wondering if you had a good yellow salt recipe. Mine works well right after mixing but after aging in the bucket it becomes much less attractive. Any help would be greatly appreciated

    1. Hi Joe and thanks for posting! Glad to share the recipes. I know my old school has a recipe but it’s the same one that is in John Britt’s cone 10 high fire glazes book. I’d assume the glaze listed here is the same one.

      After looking at these ingredients, nothing looks like it should decay or get funky like a bone ash would. Maybe run it back through a sieve?

  5. Phil,
    I’m firing cone 10 and I am looking for a rich red glaze food safe. I have used Pete’s red so far, but I am not always impressed with it.
    Do you have any suggestions?
    I really liked your thoughts on your favorite glazes, so I hope you have 2 cents on this matter as well.

    Thanks

    1. Hi Emanuela,
      I wouldn’t suggest a rich red glaze for food to sit on. Here is why. Red glazes contain copper and sometimes barium metals. These metals can leach out of a glaze if you have an acidic food like tomatoes on it. Red glazes are fine to use on the outside of mugs and cups, but for a plate or something that food will contact, I would find another color. Or, you can fire using frits at a lower temperature that have the metals chemically bound to other things.

  6. Good Day!!

    These glazes look awesome, I’m a Ceramic diploma student and am currently working on a wood/soda firing module. I really like your shino gaze and happened across it as i’m researching different glazes.
    I will be using white/buff stoneware 50/50 do you think this will have enough iron for the orange to happen?
    Also I was wondering if its possible to easily alter the glaze to crawl?

    Thanks

    Thomas

    1. Hi Thomas, thanks for the comment and kind words. I have used the shino on porcelain and I still get the orange to come through some, although it translates a bit differently. I’ll add the picture of it above so you can see for reference. Regarding the crawl, I’d bet if you just increased the clay content about 10% or more it may crawl–however I would probably just look up a crawling shino recipe if that’s the case. I purposely tried to minimize the crawl with this recipe.

  7. Have you ever used strontium in place of barium in your glazes? We’ve had really good luck using it in our studio as a replacement to help with food safety in our red glazes, etc. (I can’t remember the exact ratio for replacement right now..) but I was curious if you’d tried it in any of these.
