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.

Why a printable, for this one

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.

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.

How the guide is built

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.

Why the University is free

The lesson is free. It always will be.

All of the teaching in this guide comes from the free โ€œThe Complete Guide to Clay Bodiesโ€ 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.

Good questions

Before you buy

Is this different from the free lesson?
The teaching is the same, and the free lesson is complete. The printable adds a spec sheet log, a one-page card, five printed questions with an answer key, and a glossary.
Can I mix two clay bodies?
Bodies that fire to the same range generally blend well if you wedge them thoroughly. Mixing a low-fire body into a mid-fire one is how a shelf gets ruined, and that is the mistake worth remembering.
What actually makes a pot food safe?
Low absorption in the fired body and a glaze that fits it. The guide points at the food safe lesson for the full answer rather than pretending one paragraph covers it.
I am not at The Clay Hole. Is it still useful?
Yes. Spec sheets work the same everywhere. Where a fact is about our studio or our shelf, the guide says so.
Do I need a fancy printer?
No. It is designed for an ordinary home or office printer on regular US Letter paper, with nothing important near the edges, so normal printer margins cut nothing off.
Can I print it in black and white?
Yes. Nothing depends on color, and we looked at the workbook pages in grayscale to be sure.
Can I use it on an iPad or laptop instead?
Yes. Every QR code in the guide is also a tappable link, so on a screen you just tap instead of scanning.
How do I get it after I buy?
Right after checkout you get a download link by email and on your order confirmation page. Each link works up to seven times.
What if the guide gets updated?
Every edition carries a version number. When we correct or improve a guide, everyone who bought it gets an email with the new edition at no charge.
Can I share it with my class or studio?
Please donโ€™t. It is licensed for your own personal use. Anyone can read the full lesson free online, and the printable is here if they want their own copy.

Pick one, and change for a reason.

Print it, keep the card by the shelf, and log the next clay you try.

What you may not do is distribute the guide to anyone else, whether you charge for it or not.

That means you may not share, forward, email, upload, post, publish, copy, reproduce, resell, sublicense, redistribute, or otherwise provide the guide, or any substantial portion of it, to another person. You may not place it in a shared drive, group chat, membership library, online community, file-sharing service, studio resource folder, classroom packet, employee handbook, course, workshop, or other shared collection. You may not make copies for students, members, employees, friends, classes, studios, schools, groups, or organizations.

You may not remove or obscure copyright notices, watermarks, attribution, or other ownership information, or sell, republish, or commercially exploit modified or derivative versions of the guide.

Purchasing the guide does not transfer ownership of its copyrighted text, photographs, illustrations, graphics, layouts, worksheets, or other original content. Those rights remain with The Clay Hole and their respective rights holders. Copyright law protects the expression contained in these guides, while ideas, methods, techniques, and processes may have different legal treatment.

Pottery is wonderfully unpredictable. It also carries real risk.

We work hard to make The Clay Hole University accurate, useful, practical, and ridiculously thorough. But pottery is a hands-on craft involving countless variables that no written guide can completely control or anticipate.

Depending on what you are doing, ceramics may involve extreme heat, kilns, electricity, gas, flame, sharp tools, spinning machinery, heavy equipment, pressurized equipment, silica-containing dust, fumes, chemicals, raw materials, stains, oxides, glazes, combustible materials, hot surfaces, breakable objects, and other hazards capable of causing serious injury, illness, property damage, fire, or worse.

These guides are provided for general educational and informational purposes. They are not a substitute for hands-on training, competent supervision, your studioโ€™s safety procedures, applicable laws or codes, Safety Data Sheets, or the instructions and warnings supplied by the manufacturers of your clay, glaze, chemicals, tools, kilns, equipment, protective gear, or other materials.

Studios, kilns, clay bodies, glazes, firing schedules, electrical systems, ventilation systems, equipment, environmental conditions, application thicknesses, material formulations, and individual techniques vary enormously. Something that works beautifully in one situation may fail spectacularly in another. That is part of pottery. Occasionally, it is a very expensive part of pottery.

You are responsible for determining whether any technique, material, combination, firing schedule, tool, or process described in a guide is appropriate and safe for your specific circumstances before using it.

Use appropriate protective equipment. Use adequate ventilation and dust control. Read manufacturer instructions and Safety Data Sheets. Follow your studioโ€™s rules. Obtain qualified instruction when a process or piece of equipment requires it. Test materials and techniques before committing important work to them. If you do not understand how to perform something safely, do not proceed until you do.

Never assume that a ceramic surface, glaze, clay body, firing method, finished vessel, repair, decoration, or other result is food-safe, microwave-safe, dishwasher-safe, oven-safe, structurally sound, chemically stable, or suitable for any particular purpose solely because it appears in or is discussed in one of our guides. Verify suitability independently when it matters.

Ceramics also refuses to sign contracts promising beautiful results. Colors change. Glazes move. Kilns have opinions. Pots crack. Materials interact unexpectedly. Manufacturers reformulate products. Equipment behaves differently. The Clay Hole does not guarantee any particular aesthetic, functional, firing, glazing, structural, or other result.

By choosing to use the information in a guide, you accept responsibility for your own materials, equipment, workspace, safety decisions, testing, methods, and results. To the fullest extent permitted by applicable law, The Clay Hole and its owners, employees, contributors, and affiliates are not responsible for injury, illness, property damage, lost work, failed projects, kiln or equipment damage, financial loss, or other loss arising from or related to your use of, or reliance upon, the guide.

Nothing in these terms excludes or limits any right or liability that applicable law does not allow us to exclude or limit.

Digital guides, immediate delivery, and refunds

These are digital products delivered electronically and made available for use immediately after purchase. Unlike a physical book, a downloaded digital file cannot meaningfully be returned to us once it has been delivered.

By completing your purchase and requesting immediate access to the guide, you consent to digital delivery beginning immediately. Where applicable law provides a cancellation or withdrawal period for digital content, you acknowledge that beginning the download, access, or delivery of the digital content may cause that cancellation or withdrawal right to end.

Once access to or delivery of the purchased digital guide has begun, the purchase is final and non-refundable except where a refund, replacement, cancellation, or other remedy is required by applicable law.

If the file you receive is corrupted, inaccessible, materially different from what was described, or there is a genuine technical problem with delivery, please contact us. We would much rather fix the problem than leave you staring angrily at a PDF that refuses to PDF.
