Texture you can almost feel through the screen ✨

These carved mugs by .f.pottery show off everything we love about Vashon Gray — soft gray tones, beautiful handling, and just enough texture to make carved details really stand out.

Vashon Gray fires to a warm off-white/gray with a lightly coarse feel, making it especially satisfying for surface work like this.

Warm carving, earthy tones, and a glaze that really lets the texture shine ✨

This mug by is made with Klamath Brown clay, pairing rich natural warmth with a soft toasty white glaze for a finish that feels both rustic and refined.

Klamath Brown continues to be a favorite for makers who want depth and character straight from the clay body itself.

Clay feeling too hard? Don’t panic.

Sometimes clay stiffens up from age, storage, or temperature changes — but that doesn’t mean it’s ruined. Before you reach for water, try this instead:

Throw it on the ground. Repeatedly. Seriously.

Breaking the clay up with force helps loosen it back up so you can wedge it normally again. A little aggressive? Maybe. Effective? Absolutely.

Watch the video to see how we bring hard clay back to life 👊

Soft florals + dramatic speckles = the perfect mug for spring

This slip-trailed mug by .pottery highlights the natural character of SP658 Gray Speckled perfectly.

A lovely reminder that sometimes the clay body does half the decorating for you.

In this video, we’re walking through how to make and place your own cone packs for kiln firings — including how to orient cones correctly, why they bend the way they do, and how they help verify your kiln is actually reaching temperature.

Whether you’re brand new to firing or just want a refresher, understanding witness cones is one of the best ways to better understand your kiln.

Also yes… the cones are kissing.

We handed the new Stoneware glazes over to the SPS team… and let’s just say people got opinions 👀

From Mood Ring to Pink Pearl, Lily Pad, Tidal Wave, and Baby Blue Speck, everyone had a favorite glaze combo going in — and a different favorite after the kiln opened.

Watch to see which glazes surprised us most ✨

Which combo would you try first? Let us know below.

Say hello to Ashford 🐾

He's another good dog making the rounds at Seattle Pottery Supply — and another reminder that studio runs are better with a sidekick.

We’re always happy to meet your four-legged companions when you stop by to grab clay, glazes, tools, or just wander the aisles looking for your next project.

Pet friendly, clay friendly, people friendly. That’s how we like it.

Ready to try marbling? This is the perfect place to start. ✨

Our Klamath Clay Sample Flight gives you four of our colorful Klamath stoneware clay bodies in one easy pack: Klamath Buff, Klamath Yellow, Klamath White, and Klamath Brown.

All four fire to cone 5 and create beautiful natural contrast when layered, blended, and thrown together — making them ideal for marbling, surface design, and experimenting with movement in clay.

A great way to explore the Klamath line without committing to full blocks.
