Friendly studio tip for this glaze

Various is our own shelf grouping for the Glaze Bible, not a Spectrum line. Spectrum put this one in their Stoneware Metallics range.

What this glaze does

A bright metallic gold, even across a flat tile. Spectrum group it with their Stoneware Metallics.

Clays that suit Gold

Clay body, thickness and cone all move these, which is Spectrum's own guidance for the range.

Applying this glaze to your work

Two to three coats on cone 04 bisque. Gold Rain is the exception worth naming: Spectrum warn it runs, so keep it well up off the foot and protect the shelf.

Across the Various Families line

Two to three coats on cone 04 bisque. Gold Rain is the exception worth naming: Spectrum warn it runs, so keep it well up off the foot and protect the shelf.

Layering

Spectrum recommend overlapping their glazes for new results, and say the fired look depends on firing temperature, glaze thickness and the clay body underneath.

Before you commit a pot

Spectrum recommend overlapping their glazes for new results. A metallic over a color is where this shelf gets interesting, and a metallic that runs is where it gets expensive.

Firing Gold

Spectrum rate these for cone 4 to 6 and fire their own samples at cone 5. Our glaze kilns run cone 5½, so the tile here is the color at our cone.

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 Gold

Why does mine look different from the tile?

Thickness and clay body. Spectrum name both as the things that move the result, along with the cone.

Why is the color uneven?

These are reactive by design. Two to three coats gives full coverage; the variation is the glaze doing its job.

Food and function

Spectrum say most of their cone 4 to 6 stoneware glazes are lead free and dinnerware safe. Some of the reactive ones carry an ACMI cautionary label because of copper or vanadium in the wet glaze, which makes them unsuitable for young children or anyone pregnant to handle. Wet only. Fired and cooled, that is not the concern.

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 Spectrum Various Families pot.
  2. 2Find the tile Tiles are numbered around the pot. 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 Spectrum Various Families Family

Six Spectrum glazes that sit together on our shelf without sharing a Spectrum line. Four of them are Spectrum's Stoneware Metallics, and two come out of the 1100 stoneware range.

Various is our grouping, not Spectrum's. Every page here names the range the glaze actually belongs to.

Four metallics and two colors that had nowhere else to go. The metallics are the reason to look at this shelf: Mirror is genuinely reflective, and Pewter reads like tarnished metal. Spectrum fire their samples at cone 5. Our glaze kilns run cone 5½.

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.
