Keep one batch together
Record a single kiln run with a batch label and kiln name so the history is easy to scan later.
Safety notes
- This tool is for record keeping. It does not judge kiln safety, air quality, or process quality.
- Always follow your kiln procedure, site rules, and local regulations first.
- If an observation or temperature note suggests a problem, treat it as a site issue and act immediately.

What it does
Built for field use and later reporting
Track start and end times
Capture local start and finish times, then see the run duration at a glance.
Capture observation and temperature notes
Store smoke, draft, sealing, flame, kiln temperature, and other field observations in one record.
Export CSV or JSON
Hand the same record to a spreadsheet, report, or other system without retyping it.
Keep local history
Save drafts and history on the device, then reload, duplicate, or delete them later.
Work across languages
The UI is translated from English and ready for additional languages and right-to-left layouts.
How to use
- Enter a batch label and kiln name so the record is easy to identify later.
- Fill in charge amount, start time, end time, observation notes, temperature notes, and yield.
- Save the record, then duplicate or reopen it if the next batch is similar.
- Export the visible history to CSV or JSON when you need to share or archive it.
Examples
Standard batch
A complete record with times, notes, and yield.
Input
Batch 2026-03-26 A / Kiln 1 / charge 28.4 kg / start 2026-03-26T08:10 / end 2026-03-26T19:25 / yield 18.5%
Output
Saved as a complete record with an 11 h 15 min duration, ready for CSV or JSON export.
Batch needing review
Use this when the record still needs confirmation.
Input
Batch 2026-03-27 B / Kiln 2 / charge 1.2 t / start 2026-03-27T20:15 / end 2026-03-28T08:30 / yield 120%
Output
Marked for review because the yield is outside the normal range and needs confirmation.
Glossary
batch
One kiln run or charge cycle recorded as a single unit.
charge amount
The amount loaded into the kiln for the batch.
yield
The percentage relationship between the output and the charge amount.
observation note
Notes about smoke, draft, sealing, flame, or other visible operating conditions.
temperature note
Notes about kiln temperature, probe position, or ambient conditions.
JSON
A structured export format that is easy to hand to other systems.
Calculation notes
duration_minutes = end_at - start_at
yield_percent = output_mass / charge_amount * 100
average_yield = sum(yield_percent) / n
total_charge = sum(charge_amount)
state = draft / inProgress / complete / review
Frequently asked questions
Can I use this offline?
Yes. Data stays on this device in the browser, so you can keep recording without a connection.
What if the batch is still running?
Leave the end time blank; the record stays in progress until you fill it in.
Can I save the yield later?
Yes. Yield is optional, and the page reminds you when it is still blank.
Can I switch units between batches?
Yes. Use kg, t, m3, stere, cord, or a custom label; settings let you choose the default.
Which export format should I use?
Use CSV for a spreadsheet-friendly table; use JSON when another system needs structured data.
Does the page support other languages and RTL layouts?
Yes. The UI is translated from English and prepared for additional languages and right-to-left layouts.
Notes
- This page is for logging, not kiln automation, safety certification, or process control.
- Keep one unit system per batch when possible so later analysis is easier.
- Times use the device's local time zone and may need confirmation before external reporting.
- Clear browser history and saved data on shared devices when you finish.
