Friendly studio tip for this glaze
Let it be thick enough to move. The metallic sheen comes with the flow, so leave room at the foot and let it do what it wants.

What this glaze does
A flowing green carrying a metallic sheen, and Amaco's reference for it is Persian lusterware, the medieval technique that put a metallic shine onto a glazed surface.
It reacts strongly to texture, so relief pulls the flow and the sheen into patterns rather than leaving them even.
How much it varies
The color is dependable. Where the sheen concentrates follows the form and the thickness.
Clays that suit Vert Lustre
Translucent, so the clay shows through and shifts the green. Darker and iron-bearing bodies deepen it; white stoneware keeps the metallic sheen brightest.
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
Three coats. The metallic sheen needs a full application; a thin coat gives you a plain green.
How much it moves
A flowing glaze. Leave clearance at the foot, more if anything is layered with it.
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 has great effects layered with other Potter's Choice glazes. A flowing metallic green over a dark base is a strong combination.
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.

Common problems with Vert Lustre
Why is there no metallic sheen?
Thin application. The luster needs the glaze to be thick enough to develop.
Why did it run?
It is a flowing glaze. That flow is part of how the sheen forms, so the trade is clearance at the foot.
What to put it on
Forms and surfaces
Textured and carved work, where the flow can follow the relief. Strong on vases and decorative pieces.
Colors beside it
Metallic green sits well against dark browns and blacks, and it reads richest with a matte neighbor rather than another shine.
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 This one is tile #40. 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 Vert Lustre
June Bug gives dark green with metallic crystals. Art Deco Green floats metallic spots on a lighter green. Seaweed carries the deep green with more flow and no metal.

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.
