The two glazes made for the inside of the pot, and the reason you can put anything you like on the outside.

Liner Glazes at The Clay Hole

A liner is a glaze with one job: be completely reliable on the surface that touches food and lips. It is opaque, it is stable, it does not craze, it does not move, and it does not do anything interesting. That is the entire point.

Once you have one, the rest of the shelf opens up. The reactive that runs, the metallic that is decorative only, the crackle that would be a hygiene problem in a cup, all of them become perfectly reasonable choices for the outside of a mug whose inside is lined.

We stock two, both from Coyote's Enduro line, in gloss and satin. They are white on purpose. A white interior shows you the coffee, shows you that the pot is clean, and reflects light back out of a deep form instead of swallowing it.

This is the smallest page in the Bible and quite possibly the most useful one.

Every one we stock

Both are Coyote Enduro. Gloss reflects more light out of a deep form; satin is softer against a matte exterior.

A super durable glossy white glaze, perfect for porcelain. Gentle enough to let underglaze show through, but hard enough to repel acids and dishwashers.

Liner Glazes at The Clay Hole: How to line a pot properly

How to line a pot properly

Pour the liner in rather than brushing it. Fill the pot about a third, roll it so the glaze coats every inch of the interior, and pour the excess back out in one continuous motion. Brushing an interior almost always leaves thin patches where you could not reach, and a thin patch is exactly where a liner stops being a liner.

Then take it up over the rim by a few millimetres and stop. That small overlap means the surface a lip touches is lined glaze, not the decorative glaze outside, and it gives you a clean line to work to when you glaze the exterior.

Let the interior dry completely before you touch the outside. A wet interior is the fastest way to fingerprints in places you cannot fix.

Common questions

Why use a liner at all?

So the surface that touches food is a known quantity, which frees the outside of the pot for anything you like.

Gloss or satin?

Gloss bounces more light out of a deep form and is easier to see into. Satin sits better against a matte exterior.

Should I brush it?

Pour and roll it instead. Brushing an interior leaves thin patches where they matter most.

How far up the rim?

A few millimetres over, so the lip touches lined glaze rather than the outside glaze.

Do I need one on a bowl?

Any piece that holds food benefits. It matters most on deep forms you cannot see into.

Can I use a normal white instead?

You can, but a liner is formulated for stability and against crazing, which is the part that matters here.

Two jars, and they make almost every other glaze in this Bible usable on a mug.

About these images and what your pot will actually look like

We have done our best to represent every glaze here accurately, and you should still expect your pot to look different from what is on this screen.

Our glaze tile images are digitally created. They are built to show the character of a glaze, not to be a color match.

A screen is not a printout, a printout is not a test tile, and a test tile is not a finished pot. Each step in that chain shifts what a glaze looks like, sometimes a lot.

On top of that, the pottery itself changes the result: the clay body, how thick the glaze went on, whether it was brushed, dipped or sprayed, what was layered under or over it, where the piece sat in the kiln, how hot that spot ran, how fast it cooled, what was fired next to it, and how much texture the surface had. Two pots glazed from the same jar on the same day can come out different.

Treat every image here as a starting point, and treat a test tile fired on your own clay as the real answer.
