What is the How to Use Underglaze printable guide?
It is the free lesson rebuilt for paper: what underglaze is and why it is for drawing, the seven house rules and the reason behind each, the two brands and who can reach them, eighteen techniques with a verdict on each, how to brush it on, the firing order, and the seven ways it comes out wrong. Built to be printed, kept beside the glaze wall and written in.
Prefer to read it online first? The “How to Use Underglaze” lesson is free, and always will be.

The bottle looks like paint. It is not.
Most trouble with underglaze starts in the first minute. The color is clay, made to stay exactly where you put it, so it holds a drawn line better than anything else on the shelf and does a slow, costly job of covering a whole pot. A glaze does that in one coat.
The guide puts the whole picture in one place: what it is for, which brands and Levels can reach it, eighteen techniques with a verdict on each, how to put it on so the brush marks fill in, the firing order that keeps it clean, and what to do when it comes out pale, peeling or chipped.
It also gives you the thing a bottle cannot: a page to write on. The technique, the color, the coats, the stage of the clay, the clear you used and how it fired. After a few pieces you will know what your own colors do.
Real pages, for a glaze wall
These are actual pages from the guide, shown here with the sample watermark.

Before you beginOne page before you pick up a brush: what you will learn, what to have with you, what is worth knowing, the common pitfalls, and what a good result looks like. 
Brands and levelsThe two brands, which Level opens each, and what to do instead when your Level does not open it yet. 
Eighteen techniquesEvery technique gets a verdict on its card, how it goes right, and where the first mistake usually happens. This page opens with sgraffito and mishima. 
Every piece, and how the color came outA log to write in: the technique, the color and brand, the coats and the clay stage, the clear on top and how it fired.
Rules and a log are things you keep beside you
Underglaze work happens at a table with color on your hands. Paper suits that.
The rules where you can see them
Where it goes, how it goes on and what to do when it goes wrong sit on one page you can pin up beside the wall.
A verdict on every technique
Each of the eighteen cards says go for it, small pieces only, or ask first, so you can tell at a glance what needs a question before you start.
A log for your own colors
Columns for the technique, the color and brand, the coats and clay stage, the clear glaze and how it fired. A few pieces of notes beat a memory of what you did.
It does not mind a wet hand
A page stays where you put it. It does not lock its screen while you are holding a brush.
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 the studio’s own rules
We checked the lesson against The Clay Hole’s glaze and underglaze certification, the glaze index and the Food Safe Lookup. Where the lesson was silent or out of step, the guide now says what those pages say.
A more careful food safety sentence
The lesson said a clear glaze is what makes a mug food safe. Not every clear is rated for food, so the guide says to check the one you pick.
A safer way to scrape
The mishima card now says to scrape while the pot is still leather hard, so you get curls and not silica dust.
Numbered rules and a drawn key
The seven rules are numbered, so the line that says read rule two points at something, and the three layer cross section comes with its own key.
A quiz that explains itself
A short quiz, and an answer key that gives the reason behind every answer rather than only the letter.
Codes that keep working
Every link is a short Clay Hole address. If a page moves, we repoint the address and your printed copy still goes to the right place.
The lesson is free. It always will be.
All of the teaching in this guide comes from the free “How to Use Underglaze” lesson, and that lesson is not going anywhere.
So the rules in this guide are not there to say no. Each one protects something a lot of members share, and each one comes with its reason.
If you want to try something this guide does not cover, ask an instructor first.

Three lessons that pick up where this one leaves off
Each one is free to read online, and the codes in the guide take you straight there.
-
Guide 01.02 · free lessonThe Five Stages of ClayEvery technique here wants a stage: leather hard for sgraffito, bone dry for crayons. This guide is how to tell which stage a piece is in before you pick up a brush.
Read the free lesson -
Guide 07.05 · free lessonHow to Use Sprig MoldsIts lesson carries the wipe-back trick that makes raised detail pop, in underglaze on raw clay: the same move as this guide’s wash into texture, on a sprig instead of a stamped surface.

Guide 07.11 · free lessonImprinting TexturesIts glazing advice ends where this guide’s wash into texture starts: brush a thin dark color over the texture, then wipe it back so it stays in the recesses.

Good to know
How is this different from the free lesson?
Is this only for people who work at The Clay Hole?
Which underglazes does it cover?
Do I have to be a member to use it?
Is this too early for me?
What do I need besides underglaze?
Do I need a fancy printer?
Does it print in black and white?
Can I print just part of it?
How does delivery work?
What happens if the guide is updated?
Can I share it?
Draw with it, ask before you cover a pot
Keep the rules where you can see them, put it on in thin coats, and let it go through the bisque before any glaze touches it. The guide keeps the whole routine in front of you at the wall.
