Cone 10: Semi-gloss finish with variegated blue/light blue. Can exhibit green hues.
TIP: Because of the chemical make up, this glaze can vary between a green and blue finish. It has a satin finish. If you like the results that Robins Egg (SW116) gives you, then you will enjoy this glaze because they are made up of similar things.
Stoneware matte glazes range from solid shades to those that create interesting color variations as they move and break. Application thinkness is the key to making mattes work for you.
