What this glaze does

Solar Flare is a highly fluid light brown glaze with an iridescent crystalline surface.

Clays that suit Solar Flare

Rated forCone 5 and cone 6 over cone 04 bisque. Amaco says the line performs best at cone 5.
Any stonewareThe crystal effect comes from the glaze rather than the clay, so body choice matters less here than in our transparent lines.
Dark bodiesBerlin Gray gives the crystals more to contrast against, which suits a line built on shimmer.
RunningThese are highly fluid. Amaco recommends stopping the glaze about half an inch above the foot and using a drip tray or soft brick to protect the shelf.
Ask firstBecause this line runs, check with an instructor before putting it on anything with a tight foot or a flat base.

Applying this glaze to your work

Four coats to cone 04 bisque. Amaco recommends leaving the inside or the back of the form unglazed, and stopping the glaze about half an inch above the foot because this line runs.

Across the Cosmos line

Four coats to cone 04 bisque. Amaco is specific about the number.

They also recommend leaving the inside or the back of the form unglazed, because these run.

Firing Solar Flare

Amaco rates the Cosmos line for cone 5 and cone 6 over bisque fired to cone 04, and says it performs best at cone 5. No special cooling schedule is required, though a controlled cool grows more crystal.

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.

Common problems with Solar Flare

Why did it run onto the shelf?

Cosmos glazes are highly fluid. Amaco recommends stopping about half an inch above the foot and using a drip tray or soft brick.

Do I need a special cooling schedule?

No. A normal medium speed firing works, though a controlled cool grows more crystal.

Can I drink from it?

Amaco does not recommend this line for food surfaces.

Food and function

Amaco rates the line food safe as a material but does not recommend it for food surfaces, because the surface is not durable enough for it. Use it on the outside of pots and on decorative work.

Across the Cosmos line

Amaco rates the Cosmos line food safe as a material and still does not recommend it for food surfaces, because the surface is not durable enough.

Use it on the outside of pots and on decorative work.

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 Amaco Cosmos pot.
  2. 2Find the tile This one is tile #4. 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 Amaco Cosmos Family

Cosmos is Amaco's crystalline line, built to give microcrystalline surfaces without a special firing schedule.

The glazes are highly fluid and grow crystals as they cool, which is where the shimmer and the flowing surface come from.

Five glazes here out of Amaco's eight, rated for cone 5 and cone 6 over cone 04 bisque. Amaco recommends four coats and says the line performs best at cone 5. No controlled cooling is required, though a controlled cool will grow more crystal if you have that option.

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.
