The quick version of Blue Crawl
What this glaze does
An exciting, exotic glaze that sometimes changes from blue to green depending on where it is placed in the kiln. Ideal for adding detail to sculptures, or as an unusual finish for non-functional ware. Perfect for potters looking for something unusual, our Crawl glazes have a tree-bark surface that's rough and dry to the touch. To achieve the crawling effect, they must be applied very thick, until the dry surface of the glaze cracks before firing. They can also be used over underglazes.
A crawl glaze deliberately pulls itself apart in the firing, leaving a beaded, cracked surface rather than a smooth one. It is a texture, not a coating.
Clays that suit Blue Crawl
The crawl comes from the glaze, not the clay, so any body on our shelf will carry it.

Applying this glaze to your work
A crawl glaze is applied thick and left to do what it does. The surface it makes is not smooth and is not meant to be.
Because it breaks up, it works as an accent or over another glaze rather than as a whole-pot finish.

Layering
Coyote suggest putting a crawl over another glaze or over a bright underglaze, so the color shows through the gaps the crawl opens up.

Firing Blue Crawl
Coyote fire these between witness cone 5 and witness cone 6, which is where our glaze kilns run.
None of this is yours to manage. We handle everything on the kiln side, and every glaze on our shelves can be fired safely in our studio.
Food and function
Coyote do not recommend the Crawl glazes for food use. A crawled surface is broken and porous by design, which is not a surface for eating from.
Use it on sculpture, on the outside of a pot, or as an accent.

Our test tile pots
Every glaze family on our shelves has its own test tile pot, and it is the fastest way to decide what to put on a piece. It is a fired pot wearing the whole family, one numbered tile per glaze, on a surface built to show you what that glaze actually does rather than just what color it is.
- 1Find the pot The brand and family name are written on the rim. This glaze lives on the Coyote Crawl pot.
- 2Find the tile Tiles are numbered around the pot. The numbers match the ones in the Glaze Bible.
- 3Read it properly Look at what the glaze does across all four textures, not just what color it is.
What to look at on the tile
Some glazes tell you loudly that they run. Others hide it. Look at how the brushed lines fired: crisp edges mean a stable glaze, and edges that went soft and fluid mean it moved, and it will move on your pot too.
About the Coyote Crawl Family
One glaze, and it does something none of the others do: it pulls itself apart in the kiln.
A crawl glaze beads up and cracks on purpose, leaving a texture rather than a coating. It is for sculpture and accents, not for the inside of a mug.
One glaze, fired between witness cone 5 and witness cone 6. Coyote's Blue Crawl is the only crawl on our shelf. It is not recommended for food use, and it is at its best over another glaze or a bright underglaze where the color can show through the breaks.

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.
