Adventures in Damask

So my experiment with the underglaze and my damask stamp was a complete failure. You couldn't see it at all when it was under may slate matte glaze, and when it was on top of the slate matte, it completely disappeared as well.

Incidentally, I had some other glazes kicking around that I thought I'd try with the stamp at the same time. I used some Licorice from the Mastering Cone Six Glazes book, but this was a disaster. Really runny, and left more of a greenish/translucent-ish blur. No detail what-so-ever. 

I also had a test batch Strontium Crystal Magic kicking around and thought what the hell? Strontium Crystal Magic, from what I can gather, is a glaze attributed to Steven Hill, who does the most amazing electric fired work that convincingly looks reduction fired. This is a glaze he uses to get other glazes flowin' and movin'. And if you've been following my posts on my adventures with glaze, you'll probably notice I have a lot of "what the hell, why not?" kinda moments. Ironically, it's in these moments where I find the most interesting results.  Here's some Strontium Crystal Magic stamped onto my slate matte glaze:

So it's a little drippy. But this happened when I was stamping the image onto the pot. I saturated my stamp a little too much and it ran. So other than that what do I think?

Interesting....

But not what I'm after. I was hoping for a black image on my gray glaze. I'm not keen on the lighter Damask on the dark glaze. And the Strontium Crystal Magic seems to fir the image too much. Now don't get me wrong, there's a lot of potential in there. The effect is really quite attractive, if that's what you're going for. But in my case, it's not. I may come back to this at some point, with another idea/design but I don't think I'll pursue it any more with this particular tangent I'm on.

So where to next? I have been doing some reading and came across transmutation glazes. These are glazes that draw colour up from the clay body underneath and incorporate it into the glaze. I'm intrigued by this and have some ideas that may create more of the look that I'm after. So back to the glaze room to mix up some more tests...

And in case you're interested, here's some recipes: (please use common sense when mixing and testing glazes in your own studio).

Licorice:
Ferro Frit 3134: 26
Custer Feldspar: 22
Talc: 5
Whiting: 4
EPK Kaolin: 17
Silica: 26
Red Iron Oxide: 9
Cobalt Carbonate: 2

Strontium Crystal Magic:

Custer feldspar: 46
Whiting :17.2
EPK: 4.9
Strontium Carb: 12.6
Ferro Frit 3134: 14.6
Titanium Dioxide: 13.8

In the Beginning...

And so it begins!

This is the first official post in a series of writings I will be doing on my approach to glaze testing and how it informs the development of my work. I have two separate things on the go right now, and this post will deal with the first one.

In the beginning comes the first hint of an idea. This is where my sketch book and a giant box of pencil crayons come in handy. My mind has been juggling several different things for a while now. First of all, I've been studying my new line of work and can't seem to shake the urge to draw flowers all over it. This is not new for me. I love pattern, and am very attracted to the idea of layering, with inspiration coming from both the fashion industry and fancy-schmancy wallpapers. So here's what my brain spits out:

A window of glossy stripes with a flower in the corner, to go with my slate matte glaze that I'm totally in love with despite all its flaws. But the longer I looked at this image, the more I realized it doesn't work. At all.

So the other thing that has been whirring around in my brain is how to combine the two, very distinct, lines of work that I have going on right now. So that got me thinking about adding some Arabesque lines rather than the flowers. And here's where that idea took me:

And:

Which then led to these:

And these:

These images got me rather excited so now begins to process of determining how to go about translating these images onto the clay. I'm pretty sure I want to go with some black underglaze, or maybe even some black glaze for the Arabesque lines and the pinstripes. As for the colored glazes, at this point I'm thinking maybe some kind of interesting matte glaze in the narrow stripes, and a crackle glaze in the wider stripes. The colors I'm interested in are a soft pink, maybe a burgundy, or Merlot color, a medium blue, and a vibrant turquoise for the crackle glaze. For the matte glaze, I'm interested in perhaps a lime green, an orange, or maybe even some crazy red.

Getting an idea of the colors I'm after will help determine what type of base glazes I want to start testing. As for the crackle glaze, I just happen to have a soft pink crackle that I had been using on Christmas ornaments, the color coming from erbium, one of the rare earth metals. As for the burgundy and Merlot, I'll definitely need to use stains. Okay. No problem there. But because of the nature of those colors, I need to make sure my base glaze is compatible with the stains to get the color I'm after. Enough calcium. Check. High in the alkaline department. Also check.

Here's the glaze recipe I'll start my testing with:
it's called Kittens Clear Gloss, attributed to Kathy King:

Nepheline Syenite: 30
Wollastonite: 8
Gerstley Borate: 21
EPK: 10
Flint: 31
Strontium Carbonate: 15

As for the mattes I'll try, I want something with more visual interest, not just a matte surface. I have a recipe called Val Cushing's Cry, which a dry, sparkly matte, and another recipe that's a stunning barium matte called Super Dry Matte.

Here's those recipes:

Val Cushing's Cry:
Silica: 10
Nepheline Syenite: 25
NC-4 Feldspar: 25
Zinc: 25
Titanium Dioxide: 5
Whiting: 10
(now even though this one has a bunch of zinc in it - which can be detrimental to colour - I figure I'd give it a try anyways. What can I say. I like the sparkles.)

Super Dry Matte:
Nepheline Syenite: 59.6
Barium Carbonate: 21.1
Calcined Kaolin: 7.7
Flint: 5.8
Lithium Carbonate: 5.8

I've obviously got a lot of tests to mix up. I have on hand some Blackberry Wine stain, some Deep Crimson stain, some praseodymium oxide, some orange stain, some crazy red stain, some cobalt, some copper and some chrome to get me started. So stay tuned! If you have any questions about the glazes, feel free to ask away!
