A student who throws a mug at the Carbondale Clay Center's new studio on 12th Street can't take it to Main Street to be glazed, because the two studios now fire at different temperatures. The new 12th Street Annex runs a Cone 6, or mid-fire, program. The Main Street studio stays at Cone 10, high-fire oxidation, and the Center says plainly that "glazes are not compatible" between the two.
That split in firing temperature is the clearest sign of where the Center stands this winter. It has run out of room at 135 Main Street and is raising money for a permanent home. In the meantime it has opened a second working studio across town, and between now and mid-December its holiday calendar runs through both buildings.
The Annex is at 215 12th Street, Unit D. The Center calls it "the newest studio addition" and describes it as a second working space for wheel and handbuilding. It offers what Main Street offers: adult and youth classes, shelf rentals, independent study, Makers Membership and open studio access. Both locations sell the same clay.
The firing temperature decides how the two studios work together. Students and independent-study participants work only in the studio where their class is held, because their shelf, glaze setup and kiln are all there. Monthly shelf and studio renters and Makers Members can use both buildings, as long as each piece is glazed and fired in the studio where it was made.
| Main Street Studio | 12th Street Annex | |
|---|---|---|
| Address | 135 Main Street | 215 12th Street, Unit D |
| Firing program | Cone 10, high-fire oxidation | Cone 6, mid-fire |
| Studio access | 24/7, unless closed for programming | 9 a.m. to 9 p.m. daily |
| Office hours | Main Street office | Monday by appointment; Tuesday to Friday, 10 a.m. to 5 p.m. |
Neither studio takes drop-ins. People who want to work in clay can book a private lesson, register for a class, or sign up as a monthly shelf renter or Maker Member. The Annex has two reserved parking spots at its entrance plus shared parking beside the building, and the Center encourages walking, biking, carpooling or riding the Downtowner.
The Center has been in Carbondale since 1997, when Diane Kenney served as founding director. On the Annex FAQ it says outright that it is "bursting at the seams and cannot meet current demand." Executive Director Angela Bruno described the problem in detail to Aspen Public Radio in November 2025. One classroom was serving classes, artist studios and gallery space, and the waitlist had reached 150. "We are desperate for the space," she said.
The long-term answer is the Center's Shaping the Future Capital Campaign for a new campus. The Annex is the short-term answer. In a September report, The Sopris Sun quoted Bruno's newsletter:
"This space allows us flexibility to meet the increasing demand for more programming and outreach, classes, shelf rentals and studio time as we address waitlists and continue to fundraise toward a new building. The additional space makes creating with you here at Carbondale Clay Center even easier, and allow[s] us the flexibility to keep Carbondale dirty."
According to the Center, no capital campaign funds are being used to operate the Annex. Its operating costs come from programming and scholarship funds.
The Annex also gives the Center a fallback. As it works toward a new permanent home in 2027, it may go through a stretch without access to the Main Street studio. If that happens, the Annex would cut back its own programming and take in all current shelf and studio renters, and Makers Members could work there too. Any Main Street closure depends on decisions in the capital campaign, and the Center says its stakeholders are still weighing "building designs, locations, timelines, and financial feasibility."
So the second studio comes before the new building, and this holiday season is the first in which both studios are running.
The holiday season starts in earnest Friday, November 13, and runs through Sunday. Over those three days, the Center's two addresses and Carbondale Arts' gallery each hold an opening.
Since neither studio takes drop-ins, Sunday is the easiest way for someone who isn't enrolled to see the Annex. It is also a good chance to see the Cone 6 setup in person before signing up for a class there. The fall-session classes and independent study listed for the Annex run from mid-October to mid-December.
After opening weekend, the Center's December dates fall on three evenings, each at a different scale.
The Holiday Invitational stays up at the Main Street Gallery and The Framer until December 23, and Deck the Walls closes December 24. Someone who misses opening weekend can still buy from both shows until the day before Christmas Eve.
Even the busiest gallery nights depend on the studios behind them, and those studios are running near capacity. The Cup Auction is the Center's largest public fundraiser, and its proceeds pay for the same classes and outreach that filled Main Street to begin with. The Annex runs on programming and scholarship funds and keeps students working in the meantime.
