The "Old Faithful" Glossy Cobalt

This is the one you keep coming back to. Start with a simple clear base: 40% Frit 3134, 30% Silica, 20% EPK, 10% Wollastonite. Add 1% Cobalt Carb and 2% Rutile. Fire to cone 6 in oxidation. It comes out swimming-pool blue with a glassy finish that makes coffee look expensive. I've tested this on stoneware and porcelain. Zero drama. If your home studio glaze shelf needs a foundation piece, this is it.

Floating Blue That Actually Breaks

Everyone wants that waterfall effect. For this cone 6 blue glaze, grab a base of 35% Frit 3134, 25% Silica, 20% EPK, 15% Dolomite, 5% Zinc Oxide. Now add 2% Cobalt Carb, 3% Rutile, and 1% Red Iron Oxide. It fires to a stormy indigo where thick, breaking to tan at the edges. But watch the application. Too thin and it's just sad gray. Go heavy. Three coats. Trust me.

The Chillest Matte Denim Blue

Gloss isn't always the move. Sometimes you want something that feels like your favorite pair of jeans. Mix up 30% Frit 3249, 25% Silica, 20% EPK, 15% Talc, 10% Dolomite. Add 1.5% Cobalt Carb and 0.5% Nickel Oxide. Fire cone 6. You get a soft, satin matte surface that begs to be touched. It scratches less than you think. Actually, it's surprisingly durable. Perfect for mugs that feel good in the hand.

Speckled Blue for the "I Want Texture" Crowd

If you like a little chaos, this one's for you. Take a base of 45% Custer Feldspar, 25% Silica, 15% EPK, 10% Whiting, 5% Zinc Oxide. Add 1% Cobalt Carb, 4% Rutile, and 2% Ilmenite or granular ilmenite if you want sand-like spots. At cone 6, it blooms into a mottled sky-blue with dark flecks. It's unpredictable. That's the point. Every kiln load feels like Christmas morning.

The Subtle Blue-Gray Celadon

Not every blue needs to scream. For a whisper-quiet finish, try 40% Custer Feldspar, 30% Silica, 15% EPK, 10% Whiting, 5% Ball Clay. Add 0.5% Cobalt Carb and 2% Red Iron Oxide. It fires to a misty blue-gray in oxidation. Think fog over the Pacific. This recipe is incredibly forgiving. Great for beginners who are terrified of cobalt turning everything Smurf-colored. Apply two coats. Done.
