How to Set Up a Planner For Pottery Vintage Workflows
Most people treat vintage pottery planning like it is something out of a catalog. It is not. I have been running a small wheel for about eight years now and my first three years were basically a waste of time because I never planned anything past the throwing step. The difference came when I started tracking glaze temperatures, kiln load density, and the moisture content of the clay body before it even hit the wheel. A

workflow is just a structured way of recording what you did, when you fired it, and what went wrong so you can repeat the successful parts and avoid the same cracks next time. The actual tool does not matter. I use a spreadsheet with columns for batch number, clay recipe, cone temperature, cooling rate, and glaze thickness measurement. Some potters keep handwritten logs in a notebook. Both work. The only thing that breaks is when you skip recording the ambient humidity during drying because that detail showed up later as hairline fractures on a batch of ten mugs.What you actually need to track
The core data points are simpler than most tutorials suggest. You need the clay source and date bought, the water content when you wedged it, the forming method, the drying duration in hours, the bisque fire schedule including soak time, the glaze batch number and mixing ratio, the glaze application method and thickness measured in mils if you have a micrometer, the final fire schedule, and the test tile results or breakage count. Everything else is decoration. I learned this the hard way after a full shelf of bowls warped during the glaze fire. The supplier changed their grog mix without updating the bag label. Because I had recorded the lot number and original purchase date in my planner, I was able to contact the supplier and confirm they had switched to a coarser silica blend mid-production. Two weeks later I found a new batch labeled with the same name but firing at a different shrinkage rate. Without that record, I would have wasted another thirty pieces and still not known why.
Setting up the tracking system
Start with a blank document or a physical notebook and create these columns: date, piece ID, clay lot, water percent at wedging, form type, dry hours, bisque max temp, bisque soak time, glaze code, glaze mix ratio, application thickness, kiln load position, glaze max temp, kiln cooling method, and result notes. That is it. Every entry takes about forty-five seconds if you already know the numbers. If you are measuring moisture with a meter, add five seconds per piece. Number your pieces with a system that works for you. Some potters use a date code like 2024-0315-A where the last letter is the piece count for that day. Others use a simple running serial. I switched from alphanumeric codes to a QR code system because managing hundreds of handwritten tags on small plates became impossible. The QR code links to a row in a Google Sheet. Scanning it pulls up the full firing history for that piece. Setting it up took about two hours. The time savings started showing up within a week.

Common mistakes beginners make
The biggest one is logging the finished result without logging the process. Writing down that a bowl came out beautiful tells you nothing about why it worked. The second mistake is not recording the kiln position. Same glaze recipe fired in the front of the kiln versus the back can produce completely different colors because of airflow and temperature gradients. I once had a full shelf of test tiles where the edge tiles and center tiles differed by two full color stages on the standard cone chart. Without positional data in the planner, I would have assumed the glaze was bad and thrown out a perfectly good batch. Another frequent error is using generic firing schedules instead of recording the actual ramp rates you ran. A schedule labeled "cone 06" means nothing if you do not know whether you held at 1450 F for an hour or rushed through it. I stopped writing single target temperatures about four years ago and started logging the complete curve. The file size of my data tripled but the repeatability of my results improved dramatically. Now I can fire the same glaze recipe six months apart and get matching colors within a half cone range.
When the system breaks down
There are scenarios where detailed planning will not save you. If you are working with wild Natural clay bodies that have inconsistent mineral content from pit to pit, no amount of logging will make them fire predictably. The best you can do is record the variance and accept that some batches will behave differently. I have a stack of ten-year-old pieces from a single local clay deposit that vary by nearly two percent shrinkage from the bottom of the truck to the top. The planner showed me the pattern but it could not fix the material. In that case I switched to blending the entire delivery before wedging and treating each blend as its own lot. The other limitation is personal consistency. A planner only works if you actually fill it out. I met a potter at a workshop who had bought an expensive leather-bound logbook and filled out exactly three entries before putting it on a shelf. The tool itself was not the problem. The habit was. Start small. Log every piece for two weeks straight. If you miss a day, just resume. The data gets noisy but it does not become useless.
Integrating the planner with actual production
The trick is keeping the logging step close to the work. If you have to walk across the studio to fill out a separate notebook, you will skip it. I keep a clipboard with a carbon-copy pad right next to the drying cabinet. The moment a piece is tagged, I mark the date, piece ID, and any immediate observations like surface cracks or warping I notice before firing. The glaze mixing happens at the same bench, so I record the batch number and thickness at the same time. By the time the kiln loads, the bisque entry is already complete except for the firing schedule details. This cut my pre-kiln prep time from about twenty minutes per shelf to roughly three minutes. The time went to actual logging instead of searching for where I wrote something down. It felt slower at first because I was being more precise, but the speed advantage showed up during the cleanup phase after firing when I no longer had to guess which glaze was on which piece.
What to do with the data once you have it
Most potters collect data and never look at it again. That is like buying a microscope and leaving the cover on. Once you have three months of entries, go through them and flag any pieces with unexpected results. Look for correlations. Do certain glaze batches consistently underfire when placed near the kiln door? Do specific clay lots crack more often when dried faster than forty-eight hours? The answers are usually buried in rows you barely noticed while writing them down. I built a simple pivot in Excel that grouped my glaze results by kiln position and bisque temperature. It revealed that my glaze K-12 consistently ran a full stage darker when fired in the upper rack compared to the lower rack, regardless of the target cone. The planner had captured this pattern over forty pieces before I ever saw it. I adjusted my firing strategy to always place K-12 pieces on the lower shelf and the color matched my reference tile for the first time in two years.
A note on alternatives
If spreadsheets feel too rigid, there are dedicated pottery planning apps available. They handle photo attachments, automatic lot tracking, and calendar scheduling better than a custom sheet. The trade-off is cost and platform lock-in. I tried three different apps before sticking with the spreadsheet because every time I switched tools I lost at least a week of data migration. A well-organized Google Sheet with frozen headers and color-coded rows has survived six operating system updates and two laptop changes without a single corrupted file. That reliability is worth more than fancy features I never end up using. For studios with multiple potters, a shared cloud document works reasonably well as long as you enforce consistent column naming. I watched a small cooperative lose about six months of useful data because one member decided to record firing temperature in Celsius while everyone else used Fahrenheit. Converting the archive took an entire afternoon and still left a few rows ambiguous. Agree on the format before anyone starts logging.
Final thoughts on sticking with it
The planner will not make you a better potter by itself. It is a mirror, not a teacher. It shows you what you are actually doing, not what you think you are doing. The value comes from the willingness to read the data honestly and change your process when it tells you something unexpected. I have fired pieces I considered failures that the logs show were perfectly normal for that clay body under those conditions. I have also thrown out batches that looked fine until the planner revealed they had been dried three hours faster than the documented successful range. The system does not judge your work. It just records it.
