Friendly studio tip for this glaze
Three coats if you want red. Anything less pushes the whole pot toward the icy blue end, which is beautiful but is not what most people are reaching for.

What this glaze does
Deep red where it is thick, icy blue where it is thin, and the transition between them across one pot is the entire reason this glaze exists. It is a copper red built for an electric kiln, with a blue break on texture that no traditional copper red would give you.
The blue is not a subtle edge effect. On raised texture it comes forward hard against the oxblood.
How much it varies
Thickness decides which color dominates, which makes it steerable once you know that. The break pattern follows the texture.
Clays that suit Fire & Ice
Opaque at three coats, which is the application Amaco specifies for the oxblood red. The icy blue break happens where the glaze thins over texture rather than where the clay shows through.
Thirty three of these forty six glazes are opaque, so on most of them the clay underneath is a surface to sit on rather than part of the finished color. The other thirteen see through to some degree, and those are the ones where your clay choice really shows.
Rated forStoneware and porcelain at cone 5 and cone 6, which covers every body on our shelf.
Light bodies#16 Porcelain, B-Mix and Half & Half show these glazes closest to the test tile. Start here if you want the color on the label.
Buff bodies52 Buff and Speckled Buff run warmer and let iron specks come up where the glaze thins. On the see-through glazes that speckle is often what makes the pot.
Berlin GrayOur dark body, and the one that changes these glazes most. Anything see-through goes deeper and quieter on it.
Chasing pinholesAmaco reports this line clearing up on a smooth, low-grog body more often than not. Worth trying before you blame the glaze.
Applying this glaze to your work
Amaco is specific: three coats for the best oxblood red, shaken well, not thinned, onto cone 04 bisque, each coat dry before the next. Fewer coats push the whole pot toward the blue end.
How much it moves
Amaco's warning is about pairings. Layered results may run if it is combined with a runny glaze.
Across the Potter's Choice line
Amaco's instruction for the line is three brush coats, not thinned, each one dry before the next. Their own guidance says most disappointing results come from glaze applied on the light side. Amaco publishes an application guide showing what too thin and too thick actually look like.
Layering
Amaco says it layers well over their Celadons, other Potter's Choice glazes and their Satin Mattes, with the caution that a runny partner makes the combination move.
Before you commit a pot
Amaco's own combination tiles usually show two coats of each glaze, which lands four coats total anywhere the two overlap. Their standing advice is to test a tile before committing a piece, and to re-test when a new batch number arrives, since raw materials shift between production runs. Dipping versions of these glazes behave differently from the brushing jars and are much harder to layer.

Firing Fire & Ice
Amaco rates the line for cone 5 and cone 6, published as 2167F and 2232F on a medium speed firing, over bisque fired to cone 04. Amaco recommends a test tile with each new batch number, since raw materials vary between runs.

Common problems with Fire & Ice
Why is my whole pot blue instead of red?
The application was thin. Red needs three full coats; thin coats are the blue end of the range.
Why is the blue only on my texture?
That is the designed break. The glaze thins over raised areas and turns icy there.
What to put it on
Forms and surfaces
Textured work, where the red and blue can meet along every raised line. On a carved pot the red and blue meeting along the edges is dramatic.
Colors beside it
It contains its own contrast, red against blue, so a quiet neighbor works best. Cream, black or bare clay.
Food and function
Amaco rates this glaze food safe and dinnerware safe, lead free and AP Non-Toxic.
Across the Potter's Choice line
Every glaze in the line is lead free and, by Amaco's rating, dinnerware safe except PC-4 Palladium and PC-64 Aventurine. Amaco's own label carries the standard caution that anyone producing tableware should test finished ware, because firing temperature and contamination vary between kilns.
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 Amaco Potter's Choice 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
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.
Other glazes close to Fire & Ice
Copper Red is the same oxblood without the blue break. Flambe brings purple and blue into the body of the red. Chun Plum is the soft translucent version.

About the Amaco Potter's Choice Family
Potter's Choice is the line Amaco built so an electric kiln could do what a gas kiln does. Released in 2004, it reaches for the depth of cone 10 reduction glazes at cone 5 and cone 6 in ordinary oxidation. That is the whole premise, and it is why the surfaces break, pool, float and shift instead of sitting flat.
It is one of the most layered brushing lines in American pottery, and Amaco keeps a public library of combination tiles for it. Most of the effects potters chase come from two of these glazes meeting on one pot.
Made by Amaco, a company that has been building glazes and kilns in Indianapolis since 1919. The Potter's Choice line arrived in 2004 and has been a reference point for mid-fire reduction looks since.

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.
