Bisque and glaze firings
Bisque fires to cone 05. Glaze fires to cone 5½. Each one goes in once the drop-off tables hold enough work to run a full load.

How the schedule works
We do our best to share an accurate schedule. Some weeks the tables fill fast and some weeks they fill slowly, and a kiln only goes in once there are enough member pieces to run it.
We work to get every member piece into the kiln, and sometimes they cannot all fit. Each load shows how much member work went in.
Some days other studio needs come first, and a load or an unload moves to another day.
Now and then the kilns fire the owner’s own pottery. Those loads show up here too, marked as owner’s firings, and member work keeps filling the tables while they fire.
As soon as a load is ready for pickup, it shows up in the studio kiln log below.

Bisque kilns
Bisque fires in two Skutt kilns loaded on the same day, a Skutt 1027 and a Skutt 1227. Both are top loaders: round kilns with a hinged lid, loaded from the bottom shelf up.
The 1027 has ten sides, measures 23 inches across and holds about 7 cubic feet. The 1227 has twelve sides, measures 28 inches across and holds about 9.9 cubic feet, the widest round top loader Skutt makes. Both are 27 inches deep, so together a bisque load gets about 17 cubic feet of kiln space.
Each one runs on a Skutt KilnMaster controller that steps the kiln through its firing schedule. Our bisque loads go to cone 05.
A bisque firing starts slower than it looks like it needs to. Water still held in the clay has to leave as steam first, and rushing that part is how a pot cracks or blows apart in the kiln.
Glaze kiln
Every glaze load fires in an L&L T3454-BL bell lift kiln. The body of the kiln rises on a motorized lift while the floor and the shelves stay put, so a load gets built from all four sides instead of reached into from above.
Inside it is 43½ inches wide, 30½ inches deep and 54 inches tall, about 41½ cubic feet, built from six 9 inch sections. It weighs more than a ton and draws close to 50,000 watts at full power.
Three thermocouples read the top, the middle and the bottom of the kiln separately. The touchscreen controller on the tall panel beside it runs each of those zones on its own to keep the whole stack even.
The kiln is rated to cone 10. Our glaze loads go to cone 5½, reached with a 12 minute hold at the top of the firing.
One more kiln lives at the studio, a small Skutt GlazeTech test kiln. This page does not track it.
The name on the corner
Our studio manager, Kinley, runs the loading and unloading of every kiln in the studio and takes remarkably good care of this place.
The kiln schedule is Kinley’s. So is the corner.

It should land in the next few minutes. One thing while you wait: we are members only and we do not run walk-in tours, so the virtual tour is the closest you can get to standing in one.

One question
We started in Draper, Utah, and we would like to be in more places than that. Where they go next is the part we have not worked out yet.
Where are you?
That is how we work out where the demand actually is. The rest is so we know who to tell.
Got it
Being straight with you: this could be a long wait, and we will not email you in the meantime. If your area is where the numbers land, you will be the first to know.
