Built to be printed, kept by your shelf and written in.

For anyone whose handle cracked off or whose pot went bone dry before they got back

Most of a good pot happens in one short window.

The foot, the weight, the handle, the lid and the clean carved line all wait for leather hard, and leather hard does not wait for you. Come back a day late and the pot goes on as it is.

The guide explains why the window exists at all, what the water inside the clay is doing, and why the soft end is for joining and the hard end is for cutting. Five labeled drawings in pencil on graph paper make each part plain, from the particles in the clay to hollowing a sculpted head.

It also gives you what a web page cannot: a log for every piece you catch in the window. Write down when you came back, what the thumb and the nail told you and what you did, and a few rows in you know how fast your clay moves where you work.

Why this one belongs on paper

A page that lives by your shelf

Most of this guide is used with a piece in your hands and clay on your fingers. Paper goes there with you.

  • The job table at a glance

    Nineteen jobs that belong to leather hard, which end of the window each one wants and why it cannot wait, on one table.

  • Drawings you can read at the bench

    The water inside the clay, the thumb and fingernail test, trimming shavings, a slab box corner and a hollowed head, each printed large with its numbered key beside it.

  • A log for your own clay

    Columns for when you came back, what the thumb and nail said, the job and how it came out. A few rows in, you know your window.

  • It does not mind clay

    A page can sit on the table next to a wet pot, and it never locks its screen while your hands are full.

How this one is built

Rebuilt for paper, not printed from a web page

Every guide in the series is set from scratch for print. Here is what that meant for this one.

  • Read against our other lessons

    We checked it against our five stages, trimming, handles, score and slip, sculpting, lidded box, drying and heat lamp lessons, so the guide says what those pages say about the same window.

  • The mechanism, checked at the source

    What happens to the water and the particles as clay dries was checked against ceramic references before a word of it was written.

  • Drawings checked against the words

    Each labeled drawing was read at full size and corrected where it disagreed with the lesson, so the pictures show exactly what the text says.

  • Written for a reader in any studio

    The lines about our own studio, our shelves and our tools are written so they make sense to a potter anywhere.

  • Video notes that claim no more than the videos

    Each video note was written from the video’s own title, description and chapters, so it promises only what the video says it covers.

  • Codes that keep working

    Every link is a short Clay Hole address. If a page moves, we point the address at its new home and your printed copy still goes to the right place.

Why the University is free

The lesson is free. It always will be.

All of the teaching in this guide comes from the free “Leather Hard Clay: Soft, Hard and What Each Is For” lesson, and that lesson is not going anywhere.

Leather hard is the only stage where clay is stiff enough to push on and still wet enough to cut and bond.

Press a thumb, press a nail, hold the piece to your cheek, and you will know which end you are holding. Then bag it properly, so the window waits for you.

Questions

Good to know

How is this different from the free lesson?
The teaching is the same, and the free lesson is not going anywhere. The guide is that teaching rebuilt for paper: a learning dashboard at the front, the five drawings printed large with their keys, a piece log, a one page reference, a glossary and a quiz with an answer key that explains every answer.
Does it cover the wheel and hand building?
Yes, both, and sculpture too. The wheel section covers trimming, lids, handles and decoration; the hand building section covers stiff slab boxes, coil and pinch builds and attachments; the sculpture section covers hollowing a solid piece and adding features.
Do I need to be a member of The Clay Hole to use it?
No. It works with any clay in any studio. The few lines about our own studio are written so they make sense to a potter anywhere.
Is this too early for me?
It is marked All levels. Nothing is assumed, and the window catches out experienced hands as often as new ones, because it moves with every clay, every wall and every week of weather.
Do I need a fancy printer?
No. It is set 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.
Does it print in black and white?
Yes. The text and the tables are black on white, and the drawings are pencil on pale graph paper, so they print clearly in grey. Color is used for headings, small labels and the numbers on the drawings.
Can I print just part of it?
Yes, and most people do. The piece log and the one page reference are the two worth keeping by your shelf. They are numbered pages like any other, so you can print those and leave the rest on a screen.
How does delivery work?
It is a digital download. The link arrives by email and on the order confirmation page right after checkout, so you can have it printed before your next session.
What happens if the guide is updated?
Every edition carries its version number on the last page. When we correct or improve one, the new edition replaces the old one in the shop, and we can send the updated link to anybody who already bought it.
Can I share it?
It is licensed for your own use. Print as many copies for yourself as you like, on as many of your own devices as you like. Please do not pass the file on, upload it or use it with a class or a group without asking us first.

Join soft, cut firm

The soft end of leather hard is for joining, the firm end is for cutting, and a bag holds the window open until you are back. The guide keeps all three in front of you at the shelf.

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 studio’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 studio’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.
