Casa Cendra turns incomplete pottery-firing enquiries into compatibility-checked, correctly scheduled kiln bookings, while routing only unsafe or uncertain work to the solo owner.

How it was made — the brief, why kiln booking isn't ordinary scheduling, the eight build phases, the deterministic compatibility rules, and the owner-side cancellation recovery loop.

Casa Cendra is a fictional one-person community kiln studio in Valencia. Its customers arrive with very different levels of ceramic knowledge. Some know their clay body and firing profile. Others only know that they have four bowls, used a blue glaze and need the work before an exhibition.

That makes a normal appointment calendar dangerous. Before accepting a firing, the studio must understand the material, dryness, glaze range, temperature, dimensions, quantity and timing. Every incomplete message creates another round of questions for the owner. A wrong assumption can damage a piece, a kiln shelf or an entire shared load.

I designed Casa Cendra as a guided firing workflow rather than a generic booking form.

Customers choose the closest firing path, describe their pieces and move through a transparent compatibility check. The Kiln Fitprint explains each decision instead of hiding it behind an unexplained AI score.

The system produces one of three honest outcomes:

Ready: compatible work can continue to available kiln capacity.

Review: uncertain or specialist work enters a focused owner queue.

Blocked: unsafe work is stopped with a specific reason and corrective action.

Compatible requests are connected to real kiln stages, preliminary pricing and available capacity. The confirmation becomes a Firing Passport containing the reference, schedule, preparation requirements, reminder plan and management link.

Four meaningful paths: bisque, Cone 6 glaze, private kiln and unsure.

Structured piece intake with material, condition, profile, dimensions, count and needed-by date.

Deterministic compatibility checks for moisture, firing range, glaze, kiln fit and timing.

Clear ready, review and blocked states.

Capacity-aware kiln scheduling and preliminary pricing.

Confirmation or owner-review request without false promises.

Self-service rescheduling, cancellation and earlier-run waitlist preferences.

Persistent local demo state with a safe reset path.

The owner workspace is deliberately an operations cockpit, not a decorative analytics dashboard.

Needs-attention queue with the reason for every exception.

Today and upcoming kiln activity.

Searchable booking records and status filters.

Full compatibility, capacity, pricing and reminder context.

Approve, request information, reschedule, cancel, complete and no-show actions.

Released-capacity matching, with completed recoveries recorded alongside open slots awaiting a decision.

Activity history and deterministic demo reset.

Every simulated action is labelled honestly. The prototype does not claim that an email, SMS or waitlist message was sent when no live connector exists.

A cancelled shared booking does not simply disappear. The released kiln space becomes an opportunity the system can fill.

When capacity opens, Casa Cendra lists only the waitlist candidates who genuinely fit: same firing route, shelf demand within the released space, and a date preference that matches the run. Each candidate is shown with the reasons they match, so the owner approves a decision rather than researching one. The workspace keeps both sides of that loop visible — slots still open for a decision, and slots already recovered and filled.

Before Casa Cendra, the owner must translate incomplete messages into technical firing information, identify unsafe work, estimate kiln space, suggest a run, explain preparation and recover cancelled capacity manually.

With Casa Cendra, customers provide the necessary details once. The system handles routine qualification and scheduling. The owner sees only work that requires judgement and the operational actions that matter next.

The interface uses a contemporary Kiln Editorial system: mineral white, near-black charcoal, cobalt blue and fired-clay red. Tactile material photography supports the journey from raw clay to a loaded kiln, while bold typography and restrained motion keep the operational workflow readable.

Casa Cendra was built in Lovable using React, TypeScript and Tailwind. The final build passed 74 of 74 automated tests, TypeScript validation and lint with only pre-existing non-blocking warnings. Customer and owner flows were checked at mobile, tablet and desktop sizes, including keyboard focus, reduced motion, persistence and browser navigation.
