Glazes we do not carry

More than 600 glazes sit on our shelves. This page is the other list.

Every glaze on it comes from a brand we already buy from and is rated by its maker for the range our kilns run. You are clear to buy any of them and bring them in. Six are not, and those are marked.

What we cannot do is tell you how a glaze we have never opened will behave. What we can tell you is exactly what our kilns do, what the maker says, and where to go and read the rest.

Check a glaze before you buy it

Type a name or a product code. It will tell you whether we already have it, whether you are clear to bring it in, or whether it is one of the few our kilns cannot do justice.

One firing schedule, every time

Our glaze kilns run cone 5 with a twelve minute hold. That is the same heat work as cone ½ past cone 5, written as cone 5½, somewhere between cone 5 and cone 6. Bisque is cone 05.

There is no second schedule. We do not fire low fire, we do not hold a kiln longer for one pot, and we do not run a controlled cool down. Every load carries work from dozens of people, so every piece in it gets the same heat.

That is the whole reason this page exists. A glaze rated for cone 5 to cone 6 will behave in our kilns. A glaze that wants something else out of a firing is a gamble, and it is yours to take.

  • What we can give a glaze

    One steady climb to cone 5½ and a natural cool. Consistent enough that our own shelf of glazes fires the same way in January and in July.

  • What we cannot

    A slower cool, a longer soak, a lower peak, a crystal growing hold. Those are single pot firings, and a community kiln is never firing one pot.

  • The research is yours

    We have fired everything on our own shelves, photographed the tiles, and written down what each one does. A jar we have never opened is a different thing entirely. Read the maker before you buy it, and read them again before it goes on a pot you care about.

Where this list most often disappoints people

Low fire glazes at mid fire heat. 225 glazes below were built for cone 06, and their makers publish cone 6 results for them as well. They will fire. Colors shift, surfaces change, and on 104 of them the maker says so plainly. Every one of those rows says so too.

Glazes built to move. Fluxes, cascades and melt glazes are supposed to travel. That is the product working. Keep them well above the foot.

Anything that needs a special cool down. A true crystalline glaze grows its crystals during a held, controlled cool. Ours is the one thing on this page we genuinely cannot supply, which is why those are the ones marked 🚫.

New since last year

28 of these arrived in 2026. Two lines are brand new rather than new colors in an old line: Amaco Pearlescent and Mayco Moon Rocks. If being first with something is part of the fun, start here. Each one opens the maker's page.

Every glaze we do not carry

Sorted by brand, then by line. A glaze name opens the maker's own page in a new tab. A line name in brown opens ours, for the lines we stock part of. A 🚫 means our kilns cannot do that one justice.

762 glazes, checked against each maker's current catalog on September 12, 2026. Makers add colors, retire them and change what they publish, so some of this will go out of date and some of it is probably already wrong. Tell us when you find one and we will fix it.

Questions we get about this

Can I buy my own glaze and use it in the studio?

Yes. Everything on this page that is not marked 🚫 is rated by its maker for the range our kilns run, and it is yours to buy and bring in. The list exists so you never have to guess whether a jar is going to fit our firing.

What temperature do you fire glaze to?

Cone 5 with a twelve minute hold, which is the same heat work as cone 5½, between cone 5 and cone 6. Bisque is cone 05. It is one schedule and it does not change.

Why are some of these not approved?

Because they need something from a kiln that we cannot give them. A true crystalline glaze grows its crystals during a long controlled cool, and our kilns cool naturally. Buying one would mean paying for a result we cannot produce.

What about the low fire glazes on this list?

Their makers publish cone 6 results for them, which is why they are here. They will fire in our kilns. They were still designed for cone 06, so colors shift and surfaces change, and where the maker notes a surface problem at cone 6 the row says so.

Will you tell me how a glaze I bought will turn out?

No, and we would be guessing if we tried. We have fired and photographed every glaze on our own shelves. A jar we have never opened is somebody else's data, not ours. Read the maker, then put it on a test tile before it goes on the piece you care about.

Is a glaze I bring in food safe?

The maker's own rating is the only answer worth having, and it lives on their page rather than ours. Our food safety work covers the glazes we carry, all 716 of them, at the food safe glaze list.

I found a glaze that is not on either list. What now?

Two reasons that happens. It may be rated below cone 5 or above cone 6, which puts it outside what our kilns do at all. Or it is from a brand we do not buy from, and this list covers the seven we do. Check the maker's cone rating first, because that is the part that decides it.

Chase the pot you can see in your head

Six hundred glazes is a lot of choice and it is still not all of it.

If there is a color or a surface you keep picturing and we do not have it, the list above is where to go looking. Buy the jar. Read the maker. Put it on a test tile first. Then put it on the piece you actually care about.
