What this sheet is for
See which weight and which body gave the pots that made it to the kiln, and which batch lost half its mugs to S-cracks.
Who it is for
Production potters, studio potters throwing repeat forms, teaching studios and anyone making a run of matching ware.
How to use it
- Name the batch and record the clay body, its lot number and whether reclaim was in the mix.
- Add a row for each form, with the ball weight you threw it at.
- Fill in the counts as the batch moves: thrown, trimmed, handled, to bisque.
- Write losses against the row they happened on, with the reason.
- Note what to change next time at the bottom before you forget it.
What is on the sheet
One page, top to bottom:
Printed under the title: A batch of thrown ware followed from the wedged clay to the shelf: the clay body, the count made, the weights used, the trimming, and how many survived drying.
Wet work only. Ball weights, drying times and the number of pots a body will stand before it slumps are all yours to find out and write down. Kiln schedules and glazes belong on a firing log, not here — this sheet stops at the greenware shelf.

Questions
Why no ball weights or drying times on a pottery sheet?
Because they depend on your body, your forms and your studio. The weight that makes your mug is a thing you have worked out, not a thing we can tell you, and writing it down is what lets you make the same mug next month.
Where do the firing and glaze go?
Not here. This sheet stops at the greenware shelf on purpose. Kiln schedules, glaze batches and results belong on a firing log, where they can be compared across many batches of ware.
