What It Costs to Build a Salt Kiln in Utah
A salt kiln is a technical project, and it is also a financial one. Here is what goes into the cost, before and after the first firing.
Building a salt kiln in Utah can cost several thousand dollars, sometimes much more, depending on size, materials and whether you hire out labor. Then every firing costs fuel, salt, time and wear on the brick. I saved for years before building because salt firing needs real infrastructure.
- Build costs: firebrick, fire clay, shelves, steel, arch materials, burners, safety shutoffs, flue and a concrete pad
- Running costs: fuel, 12 or more hours of active firing, salt, and brick repair
- Salt vapor is corrosive, so upkeep is part of the deal from day one
Building a salt kiln in Utah is not just a technical project. It is a financial commitment. When I decided salt fired pottery would be central to my work, I knew access would eventually become the limit. There are not many active salt kilns in northern Utah. If I wanted to fire consistently, I would need my own. That realization came with a second one: this would not be cheap.
What the build costs
A salt kiln needs more than stacked brick. The core expenses look like this: high quality firebrick, both hard and soft; fire clay to mortar it all together, plus kiln shelves; steel framing or structural support; arch materials or castable components; gas burners and regulators; safety shutoff systems; flue and chimney materials; and a concrete pad or foundation. And that is before the first firing ever happens.
Depending on size and design, building a salt kiln can cost several thousand dollars, and sometimes significantly more. The final number depends on scale, materials, and whether labor is hired out or done yourself.
Saving before stacking
After my first salt firings at Utah State University, I knew I wanted this long term. But wanting a kiln and building one are different things. So I started saving. Kiln projects do not move fast when you fund them responsibly. I have had to think about timing, studio priorities, and whether each purchase moves the project forward in a way I can sustain.
It would be easier to stay small and electric. But salt fired pottery needs infrastructure, and infrastructure needs patience.
The costs that keep coming
The investment does not stop after construction. Every firing needs fuel, natural gas or propane. It needs time, often 12 or more hours of active firing. It needs salt. And over time it needs maintenance and brick repair. Salt vapor is corrosive. Kilns wear down, and components eventually need replacing. A salt kiln is not a one time expense. It is a long term relationship with upkeep built in.
Why it is worth it
If this were about convenience, it would not make sense. Salt firing is slower, more expensive and more labor intensive. But it produces surfaces that cannot be made any other way. Flame path, vapor movement and kiln atmosphere all shape the final piece. When someone holds a salt fired pot, they are holding the result of fuel, chemistry and sustained heat, not just a glaze recipe.
For me, building this kiln is about committing to a direction and saying the process matters enough to invest in. There is risk, as there always is when you build something substantial. There is also clarity. Once the kiln is done, salt firing will not be occasional. It will be the foundation of the work.
When you price out a kiln, add a separate line for the first year of firings: fuel, salt, shelves you will crack and brick you will patch. That number surprises people more than the build does.
The bricks cost what they cost. What I am really paying for is the chance to fire the way I want to, as often as the work needs.
