Shared studio kilns · 8 to 20 members
The kiln is busy until it's cool, not until it's done
A calendar books the hours you type in. Kiln Slot books the firing profile, counts the cool-down as occupancy, and shows the queue everyone can actually plan against.
One kiln free · no contract · export and leave whenever
A cone 6 glaze firing. Eight hours of ramp and hold, then twelve hours of cooling before the door opens. The slot is the long bar, and the calendar only ever knew about the short one.
Book the profile, not the hours
A booking is a firing profile: a peak, a hold, and a cool-down. The queue derives the hours from that, so the kiln is marked occupied for exactly as long as it is hot — which is the interval a calendar has no way to know.
The free time is real
What the board shows as free is a door you can actually open, not an hour someone typed in.
You stop arbitrating
The queue answers whose turn it is, so the studio lead is not the kiln's receptionist.
Collisions become impossible
A booking cannot start inside another firing's cool-down, because the cool-down is part of the booking.
Price
One kiln
Free, up to eight members. Most home and teaching studios never leave this tier.
Studio
$9 a month. Any number of kilns and members, one queue per kiln.
Export the queue and leave at any time. No contract and no minimum term — a studio tool that holds your schedule hostage is not a tool.
Why the shared calendar keeps failing
- Someone books "kiln, Tuesday 9–5" and the kiln is still at 400°C on Wednesday morning.
- The third argument this month about whose turn it is, and you are the one settling it.
- Bisque and glaze runs get stacked back to back by people who did not know the difference.

How a slot is worked out
A profile carries its peak, its hold and its cool-down estimate — six schedules cover most studios.
One · profile, not hours
The slot runs from load to door-open, so the hot hours after the elements switch off are inside the booking.
Two · cool-down is occupancy
One queue per kiln, visible to everyone, so there is a single answer to whose turn it is.
Three · one queue, one truth
Questions
We already have a shared calendar. What does this add?
A calendar books hours you type in. It has no idea that a cone 6 glaze firing holds the kiln for another twelve hours while it cools. Every collision in a studio happens in that gap.
Does it control the kiln?
No. It touches nothing electrical and reads no controller. It is a queue that understands what a firing profile costs in hours.
What if someone fires without booking?
Then the queue is wrong, and no software fixes that. What it can do is make the honest path the fast one: booking a profile takes two taps and shows everyone the real free time.
Can we use our own profiles?
Yes. A profile is a name, a peak, a hold and a cool-down estimate. Studios that fire the same six schedules set them up once.
What happens to our data if we leave?
Export the queue and go. No contract and no minimum term.
Stop settling kiln arguments
One kiln and eight members is free, permanently. Set up your six profiles once and let the queue answer.
