Spectrum Shino Glazes and Combinations

With a lot of glazes, you don't really know what to expect when you open the kiln lid. It's even more surprising when you use Shino glazes! The use of soda ash in the glaze, causes carbon to be trapped, resulting in interesting spotting and runs.

In today's post, I will show you a few examples of Shino glaze in action. You will see results when Shino is layered over and under other glazes. You might even get to see what it looks like all by itself!

Grab your coffee and follow me to the studio. And, if you haven't already, fire up the computer and get ready to order some Shino for your inventory. I'm sure you will love the results as much as I do!Let's start with the different clays I used for the pieces you will see. I generally use a buff speckled clay like Laguna WC- 393 however; that's just my preference. I also used a Cone 6 white stoneware.

Shino glazes will work on most clays that fire in the same range as the glaze, however; the results will most likely be different. Make sure to test out the glazes, and combinations, on test tiles or "disposable pieces" before you cover your good wares with it.

There are multiple techniques for applying Shino glazes.

  • Brushing
  • Dipping
  • Trailing
  • Spraying

The following piece was dipped in Amaco Potter's Choice Deep Firebrick, then 3 coats of Spectrum Citron Shino were brushed on.

If you take notice, in the second picture, I left a bare space at the bottom of the pot when I dipped it. I did however cover it with the Shino. I wanted to see what the Shino looked like on its own with this particular clay.

This next piece was one we did a few weeks ago.

I applied a slip on the base pot, then fired to cone 04. I thought the Spectrum Jalapeno Shino would look nice, so I gave it a try. I poured the Shino into the pot then poured it out, then I brushed three coats on the outside.

Although it looks nice, there are some definite defects. If you look closely, there are a few pits created by the "off-gassing" in the base glaze. The off-gassing bubbles through the Shino and creates pits, in this case, all the way to the clay. Because of that, this pot is NOT food safe. Bactria can grow on the bare clay.

You will also notice how the Shino ran off the sides and fused the pot to the shelf. The question is, was it the slip? Is it this particular glaze/clay combo? Or do I need to apply it in thinner layers? More testing needed!

Here is an example of the Shino applied first, then the pot is dipped into a Spectrum Nova Dipping Glaze. Notice the difference in the blending an runs! LOVE IT!
