Can You Make Functional Pottery From Utah Wild Clay?
Can you actually make pots from clay you dig yourself? The honest answer is sometimes, and rarely straight from the shovel.
Yes, you can make functional pottery from Utah wild clay, but it rarely works on its own. Many samples do not vitrify enough, so I blend them with a stable commercial body, use them as slips, or try them in glazes. It takes testing, blending, adjusting and failing.
- Utah wild clay is dozens of different deposits, not one material
- Functional pots must vitrify, survive heating and cooling, and hold water
- Even a percentage of local clay brings the landscape into the work
This is the question that comes up almost every time I talk about digging clay locally: can you actually make pots from it? The honest answer is sometimes.
Not one clay, but dozens
Utah wild clay is not a single material. It is dozens, maybe hundreds, of different deposits shaped by ancient lakes, mineral shifts, erosion and time. Some are rich with iron. Some are sandy. Some are incredibly plastic. Some barely hold together. Just because something feels like clay in your hand does not mean it wants to become a functional pot.
I have tested small batches from around Cache Valley: drying them, slaking them down, sieving out debris, and forming test tiles and small pieces. The first few attempts were humbling. One cracked clean in half while drying. Another warped so badly in the kiln it looked twisted. One melted faster than expected at cone 10. That is part of the process.
What functional pots demand
Functional pottery asks more of clay than sculpture does. A mug has to survive repeated heating and cooling. A bowl has to hold water without weeping. The clay body has to vitrify properly, which means it becomes dense and glass-like enough to be durable. Many Utah wild clay samples do not reach that point on their own.
Blending, slips and glazes
That does not make them useless. Some work beautifully when blended with a stable commercial clay body. A percentage of local wild clay can bring subtle color shifts, speckling or mineral variation without compromising structure. Some deposits perform better as slips. Others show promise in glaze tests. The goal is not purity. It is understanding.
If I am making pottery in Logan that reflects this place, I do not need every piece to be 100 percent dug from the ground. But bringing in Utah wild clay, even partially, puts the landscape into the work in a literal way. There is something grounding about that.
The short answer
Yes, you can make functional pottery from Utah wild clay. But rarely straight from the shovel. It takes testing, blending, adjusting, failing and paying attention, and honestly, I am still learning. Some tests sit on my shelf as reminders of what did not work. Others hint at possibilities I have not fully explored yet. That is the part I am drawn to: the conversation between the ground and the kiln. It is slower than ordering a bag of clay, but it feels more rooted.
Start blending at small, even steps: 10, 20 and 30 percent wild clay into a commercial body you already know. Fire them side by side. The step where the tile starts to warp or stay chalky tells you your ceiling.
Still digging small buckets and firing smaller test tiles. When a wild clay piece is ready for the shop, you will hear about it here first.
