Like looking up at the prettiest pastel sky ☁️🩵

This dreamy piece by combines Pearl White with Norse Blue, Pink Gloss, and Rose Quartz for a finish that feels soft, airy, and almost watercolor-like.

And underneath it all is SPS Sea Mix 6, giving those delicate blues, pinks, and whites the perfect soft off-white backdrop.

Driftwood escaped the flight.

Originally available only in our Speckled Clay Flight, this cream-colored speckled dream got enough love that we decided it deserved to fly solo.

It fires to a warm white with black-brown flecks that start showing up around Cone 4, get darker as you fire hotter, and stay bloat-free all the way up to Cone 7. Pair it with SP217 White for maximum cottage-core energy, or hit it with SP52 Shadow Green and let those speckles do their thing.

Easy to throw, easy to work with, very easy to become emotionally attached to.

Gray Speckled is one of those clays that makes everything look a little cooler. 🩶

Built on our Sea Mix 6 clay body with added manganese and magnetite, it fires to a silvery gray with those little brown freckles we all know and love.

It behaves itself on the wheel, plays nice with handbuilding, and looks really good doing it. Basically, no notes.

Best results at Cone 4–5. 🏺

A good mug should make your coffee taste at least 10% better. We don’t make the rules. ☕️

experimented with a new mug shape here, plus some added texture on the bottom, all made with SPS Vashon Gray.

We love how the true gray clay and lightly coarse texture work with a piece that’s all about shape, feel, and those little details you notice when you actually pick it up and use it.

Okay, this officially has us in the fall mood. 🎃🍂
pottery let SPS Fool’s Gold be the star of these ceramic pumpkins, leaving the warm, speckled clay unglazed and pairing it with metallic stems finished in Ancient Copper.

The matte Fool’s Gold next to that metallic finish is such a good combination, especially with the natural dark speckles tying everything together.

Fall pottery season, we are READY.

If fall had a clay collection, this would be it. 🍂🖤
and.louie brought together SPS Eclipse and Hellborn Red for these moody, woodsy pieces, and the warm clay bodies paired with those deep glazes are doing everything we want fall pottery to do.

Finished with SPS Black Moss and Oatmeal Rust, plus Ancient Jasper, Honey Flux, and Matcha Gloss. So many good colors, textures, and glaze interactions happening here.

We’re ready for sweater weather now, thanks.

This may be your sign to finally try porcelain 👀

We know porcelain can be a little intimidating. It has a reputation for being finicky, harder to work with, and something you save for when you're a "better" potter. But why wait?

Meet the SPS Porcelain Clay Flight: four 12 lb blocks of our mid-range porcelain bodies, all happiest at Cone 5, so you can fire right alongside your other mid-range work.

- CKK6: porcelain meets stoneware! Less fuss than porcelain, so it's a great place to start
- Awaji Porcelain: smooth, plastic, and versatile
- Dove Porcelain: soft, creamy, and basically marshmallow on the wheel
- Seattle Freeze: buttery, beautifully white, and translucent when thin

Throw with them. Build with them. And find out which porcelain is your porcelain.

Plus, the whole 48 lb flight ships FREE in the U.S.

Porcelain doesn't have to be scary. Shop the Porcelain Clay Flight online and give it a go!
