What this glaze does

A beautiful, but runny, glaze, similar to the Archie's Base but more reliably pink. Combines well with any Coyote glaze.

Coyote are unusually blunt about this line: it can be challenging to use, and it rewards skill. These glazes flow and interact with other colors dramatically, and slow cooling changes them again.

Clays that suit Rhubarb

Coyote say plainly that the Archie's may not fit all clay bodies, and ask you to test for shivering.

Coyote say plainly that the Archie's may not fit all clay bodies, and ask you to test for shivering.

Test firstThis is the one family on our shelf where the maker asks for a test tile before you commit a pot. Shivering is a fit problem between glaze and clay, and it is worth ten minutes to rule out.
Any body, with a checkWe stock #16 Porcelain, B-Mix, Half & Half, 52 Buff, Speckled Buff and Berlin Gray. Try your combination on a tile before a large piece.
On textureThese flow, so they pool in carving and thin on the ridges without any help from you.
Worth knowingCoyote say crystals can form in the liquid glaze if it is stored below 65F.

Applying this glaze to your work

These move. Coyote describe them as flowing and interacting with other colors, which is the point and also the risk. Keep them up off the foot and think about what is underneath before you brush.

Slow cooling affects this line strongly, so the same glaze out of a different firing is a different pot.

Layering

This is the line Coyote built to interact. Their Gloss series is recommended under the Archie's, and several of the Satins are recommended under them too.

Firing Rhubarb

Coyote fire these between witness cone 5 and witness cone 6, which is where our glaze kilns run.

If you are a member here

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 warn that the Archie's may not fit all clay bodies and ask you to test for shivering on your clay. Shivering is the glaze flaking off under tension, and it is the one glaze fault that makes a pot genuinely unsafe to use.

They have all their recipes reviewed by an independent toxicologist and none use lead. Test your own finished ware.

Test tile pots lined up on the glaze shelves at The Clay Hole

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.

  1. 1Find the pot The brand and family name are written on the rim. This glaze lives on the Coyote Archie's pot.
  2. 2Find the tile This one is tile #6. The numbers match the ones in the Glaze Bible.
  3. 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

Broad vertical textureA broad open surface. Shows the color at full strength, and whether the glaze travels down it.
Shallow textureA shallow swirl stamp. Shows whether light carving still reads once the glaze is on, or fills in and vanishes.
Deep textureCut lines. A deeply rough texture stripe. Shows where the glaze pools, how it breaks, and how dark it goes in the recesses.
Wipe-away textureGlaze wiped back to bare clay. Shows what the edge does where the coat runs thin. Find this wiped away on the tile's number.
One trick worth knowing

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 Archie's Family

The difficult, spectacular end of the Coyote shelf. These flow, react with whatever is underneath, and change again depending on how the kiln cools.

Coyote describe the series as challenging to use and say it rewards skill, which is a fair warning and a fair promise.

Eleven glazes, fired between witness cone 5 and witness cone 6. Coyote say these create finishes unlike anything else possible in an electric kiln, and that they are strongly affected by slow cooling. They also ask you to test for shivering on your clay, which is worth doing before a pot you care about.

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.
