I'm looking for an underglaze that will give me the same color as in the picture at cone 6.  Any one have a clue where I can get some?  I'd even be interested in a glaze.

You can tint underglazes by mixing colors. Probably your best bet to get something exact. Start with a turquoise and go from there. Be aware that most manufacturer sample tiles are fired at low fire temps, not cone 6.

By the way the color moves on that piece, it looks like it was glazed. I don't think you can get that lovely color range and toasty shades with a coating of underglaze.

I was kind of thinking the same thing Chris.

The color reminds me of Slate Blue from Mastering Cone 6 Glazes. But, the finish gives the appearance of being salt fired, or wood fired -- with the color coming from a colored/oxide slip.

Slate Blue you say? Great color. I have said book, and am working my way through it. I'll have to make a note to try that one.

I have gotten a color that looks like that using laguna antique blue over speckled buff clay at cone 5, electric. I think I thinned the glaze a bit, and put on 3 coats.

If you are interested in using under glazes I would suggest using AMOCO Velvet Underglaze Series, royal blue and hunter green. (The hunter green looks like a light turquoise in the jar but is in fact a dark green) Dip a wet brush into each color and brush it onto the surface. Stop and repeat as soon as the colors blend. A satin mat overglaze on top of that. Repeat this until the ware is completely covered or you get the look you like. I agree with the others that you are looking at the results of a glaze and firing on the piece in the picture.

The color and Texture look very close to a glaze I am using.  its called Laura's Turquoise

cone 10 reduction. works well in oxidation.   whiting 34%, Custer feldspar 22%, kaolin 28%, silica 8%, cobalt carb 0.2%, copper carb 2.9%, Rutile ceramic  2.9%,  Bentonite 2%, 

try a small batch and let us know what you think.  have fun Tom

I was thinking it was a clear base, for where the leaf is. Then the same glaze with a mason stain tint. The meeting of the clear against the color makes me think it's the same glaze. The speckles being iron in the clay. I've seen the technique before.
