Cone 6 oxidation: Frost Blue is a mottled blue soft matte glaze that breaks a muted green/gray.
Cone 10 reduction: 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.
