Shino and Orange Peel

Since posting this Shino Tea Bowl on my facebook page I’ve received several emails asking what glaze combination(s) I used. The fact is this is a single application of a shino glaze I use quite often. The trick in achieving this subtle glaze variation is in how you treat the leather hard greenware.

If you click on the image of the bowl above you will see that there is a textural difference, as well as a color difference, between the rim and the body. This is a result of how the shino glaze is reacting to the different leather hard surface treatments. The rim is the original thrown surface with the fine clay particles intact (smooth). The body of the bowl has been lightly trimmed, just to “break” the surface to expose the “toothier” aspects of the clay body. When the bowl is glazed, by dipping, the glaze will adhere to the smoother clay in a more consistent and controlled manner, while it will be absorbed in a more inconsistent way on the “toothier” trimmed areas. Actually, the glaze on the rougher areas will create an audible bubbling, sucking sound and the drying glaze will exhibit “pinholing”. Shino being a highly viscous glaze, these pinholes will result in a soft “Orange Peel” finish on the surface of the fired piece. I find this finish desirable, particularly in contrast to the smoother and slightly color shifted rim. This technique will work with most shino type glazes.

Please notice the foot of the bowl. Obviously the foot was trimmed, but by “burnishing” it after trimming with your fingers a smooth finish is again established which will receive the glaze in a similar manner as the lip.

When working with shino type glazes, think about a little scraping.

    Woof!
    These are so, so nice Michael,
    You’ve had me really rethinking the chemistry of my cone 10 surfaces over the past few months. Thank You!

      Zygote,
      We’re all in this together…I’ve been thinking a lot about what’s below the surface, I think there’s something there to look into. Thanks for check’n and for your comments, I really appreciate it.

      Hi Kim,
      Here’s a link to the shino recipe on the bowl above:
      https://dmichaelcoffee.wordpress.com/2010/05/23/todays-tribal-shino-matcha-chawan-052310/

      Also, remember that shino is highly dependent on several factors and can look so different as a result of, clay body, bisque temp, application thickness, time between glazing and firing, firing schedule, etc. So, even though I’m giving you my shino recipe it remains to be seen if you will achieve similar results. Also, the orange peel affect is the result of lightly trimming the exterior surface of the bowl when leather hard…
