School and studio surplus
School studio kiln resale value worksheet
Estimate school or studio kiln resale value with capacity, voltage, controller, removal logistics, element condition, and furniture completeness.
Who this worksheet is for
Art departments, community studios, and surplus coordinators pricing a working kiln without overpromising condition.
Large school kilns can be valuable, but buyer fit depends on power, access, maintenance records, and whether the kiln can be picked up without professional rigging.
Before you trust a number
- Collect service records, last firing date, cone or program used, and whether the kiln reached temperature evenly. 1
- Confirm voltage and phase from the plate instead of assuming a home studio can run the kiln. 2
- Separate kiln furniture, vents, carts, and controllers into a clear included-equipment list. 3
- State loading limits, hallway width, elevator access, and pickup deadlines before negotiating price. 4
How to adjust the range
Best case
Documented maintenance, digital controller, complete furniture, single-phase power, and straightforward loading.
Discount case
Three-phase or 208V power, older relays, worn elements, limited pickup windows, or incomplete furniture.
Walk-away case
No safe disconnect plan, severe jacket damage, unreliable controller, or removal cost higher than resale value.
