What is the printable edition of The Complete Guide to Clay Bodies?
It is the free lesson of the same name, rebuilt as a workbook. It sorts every clay you will meet into three families by how far the fire tightens them, then teaches the six numbers on a spec sheet: cone range, shrinkage, absorption, grog, plasticity and fired color. Then the specialists, from grogged sculpture bodies to paper clay, and an honest way to choose. On paper it adds a spec sheet log for the clays you try, a one-page card, five questions with an answer key, and a glossary.
Prefer to read it online first? āThe Complete Guide to Clay Bodiesā is free to read, and always will be.

Pick one, learn its moods
Most potters inherit their clay the way they inherit a phone plan: somebody handed it to them once and they never thought about it again.
But the bag decides the color, the strength, the weight, whether it survives the dishwasher, and whether that speckle you love shows up at all.
Every serious clay comes with a spec sheet, and once you can read it you can predict how a body behaves before you ever wedge it.
Real pages, for the clay shelf
These are actual pages from the guide, shown here with the sample watermark. The full guide has none.

The big threeEarthenware, stoneware and porcelain, sorted by how far the fire tightens the clay. 
Reading the bagCone range, shrinkage, absorption, grog, plasticity and fired color, explained one at a time. 
The spec sheet logOne row a clay: the numbers off the bag, the grog you can feel, and the fired color against the wet. 
The specialistsGrogged and sculpture bodies, speckled clays, porcelain adjacent whites, paper clay and colored bodies.
A card for the clay shelf
You choose clay standing in front of a shelf or a spec sheet, not at a desk.
The clay body card
The three families, the six numbers, the specialists and the short version of choosing.
A spec sheet log
The clays you try, with their numbers and what they actually did.
Six numbers, decoded
What each one predicts about the pot you have not made yet.
An honest way to choose
Match the body to the work, not to the romance.
Built to be used in front of a shelf
Every guide in the series is designed as a workbook first and a document second. For this one, that means:
A learning dashboard before page one
What you will learn, what you need, the traps, and what success looks like.
Three families, one test
How far the fire tightens the clay, which is the line that actually divides them.
The six numbers
Cone range, shrinkage, absorption, grog and tooth, plasticity, fired color.
The specialists
What each one is for, and what it costs you.
A two minute drill
Five things to find on the bag in front of you, with boxes to tick.
Codes that keep working
Every QR code points at a short Clay Hole address, so a printed copy keeps working when a video moves.
The lesson is free. It always will be.
All of the teaching in this guide comes from the free āThe Complete Guide to Clay Bodiesā lesson at The Clay Hole University. No paywall, no sign-up, no catch.
The bag you wedge from decides more about your finished pot than any glaze ever will. Learning to read it takes ten minutes and changes what you can make, so the lesson stays free.
The University is free and stays free. The guides are the version rebuilt for paper with an unreasonable amount of care, and buying one keeps the free side going.
Thank you. Genuinely.
Dan Pearce, founder of The Clay Hole
