This is for all those who like shino glazes. I've been testing some recipes from the Dec 1992 issue of the Studio Potter. Here's what I came up with. 1) Original Wirt #1: Beautiful white glossy glaze. Very slight crazing. 2) Original Wirt #2: Very beautiful white glossy glaze. Hardly any crazing at all. Recommended. 3) Freer Sample II: Another beautiful white glaze. Where thick, some crazing. A good candidate for a liner glaze. 4) Malcomb Davis: A shino in the orange range of color. Much crazing but very beautiful glaze on outside of utilitarian pots. 5) J R "Orange": Wow! Can't believe the name of this glaze. My test looks like a wonderful celadon glaze. If it were me that developed this recipe I'd call it a celadon! 6) Hank Murrow: Sort of an off white color tending toward a gray-ish color. Nice color but a tad bit 'matte' for my tastes.7) J R 1999: Beautiful white glossy glaze. My favorite by far. No crazing at all on my clay body. Fantastic liner glaze. 8) J R 2016: Very, very matte. Looks like granite. Feels like stone. Would be interesting on sculptures. 9) Gustin #6: Really nice white glaze. Very little crazing. Would make a nice li
ner glaze. 10) Gustin's Wirt #1: Color difficult to describe. Those possessing the book 'Shino and Oribe Ceramics' see plate #79. Sort of a grayish-white color. 11) Jefferson #2: Very matte and crazing. An art dealer I showed the test to thought it would make a nice "decorative" glaze. Very matte. White-grayish in color. 12) Shafer's shino: Very nice indeed. Beautiful white color w/no crazing on my clay body. Takes a really nice iron decoration. Recommended for vessel interior glazing. 13) J R Blaze: Should be called a celadon glaze IMO. Beautiful clear glaze but with lots of crazing lines. Looks like a nice clear glaze at cone ten. That's all folks, Jim Bozeman

Dear Jim;
I am puzzled at the lack of color in the shino results you have
reported. Jim Robinson (JR) and I are getting superb blood red shinos from
our glazes in varied firing conditions. I would be very interested in
knowing how you fire and what materials you used in the JR and Hank's
glazes. As you can see in my shino article (Sept CM) My results are quite
colorful. Of course, This whole post is presumptious. Maybe you like what
you are getting, but folks may like to know that wild color IS possible
with these glazes.
Best regards, Hank in Eugene

Hank and all, The Jim Robinson article points out that shino falls into 5 different categorys. Being a utilitarian potter I selected the recipes that I thought would be good for liner glazes. As Hank correctly points out, there are many different color variations for shino. From orange to gray to white to clear and all points in between. My clay body is from Mother Earth, I dig my own clay. It is a stoneware clay that I dig on the Fall line in SC. I start reduction at cone 09. All tests were fired to cone ten. For those who wanted pics; sorry I don't possess a digital camera. More tests for using ash, powdered glass, and feldspar will come in the future. Best all, Jim Bozeman
