Pro Series

4 glazes / The Ceramic Shop

The Ceramic Shop mixes its own cone 6 glazes in Pennsylvania and sells them mostly as dry powder to studios that dip. Four of them are on our shelf.

Three are from their Pro Series. The fourth, Seaglass Aqua, is from their Sea Glass line and lives here because it sits with the others on the shelf.

Friendly studio tip for this glaze family

This shelf is four glazes, and two of them do something you can steer.

Jewelry changes with thickness: thin breaks to a transparent green on the edges, thick builds a turquoise blue. Tidal Pool changes with texture: smooth stays blue-green, carved goes warm brown.

The other thing to know is that this line was designed to be dipped, not brushed. That makes an even coat matter more here than on a reactive line where uneven is the whole idea.

Built to look like it came out of a wood kiln. The Ceramic Shop photograph it on a buff stoneware tile half painted with porcelain slip, which tells you most of what you need: the lighter the ground, the more of the ash effect you get.

Dark blue and green with flecks of light blue through it, in The Ceramic Shop's own description. It breaks on texture and comes back warm brown where it does.

This one is from The Ceramic Shop's Sea Glass line rather than the Pro Series, and it sits on our shelf beside them. They describe the Sea Glass line as transparent and matte at the same time, built out around their Matte Clear.

How the Pro Series line works

A small shelf, and a different animal from the big brush-on lines beside it.

The Ceramic Shop formulates these for dipping. They thin with water for spraying, and if you brush them they recommend adding a brushing medium first. Ours are set up as brush-on, so the thing to aim for is an even coat rather than the thick-and-thin trick some reactive lines reward.

Coats

Cone 6, which is where our glaze kilns run.

Because the line was built to be dipped, the surface rewards evenness. Where thickness does matter, and on Jewelry it matters a lot, it is called out on that glaze's own page.

Layering

This is a four glaze shelf, so there is no published combination chart to work from.

Two of them do their own layering without help. Jewelry changes color with thickness and Tidal Pool changes color over texture, which gets you variation from a single jar.

Food and safety

Lead and cadmium free, non-toxic, conforming to ASTM D-4236.

The Ceramic Shop tells anyone producing dinnerware to test their own finished work, since clay body and firing both move the result. Their dry powder carries a California warning for silica and lithium carbonate, which matters in a mixing room rather than on a fired pot.

Clays that suit Pro Series

These behave differently from each other on clay, so the short version is on each glaze's own page.

Light bodies#16 Porcelain, B-Mix and Half & Half. Electric Ash is photographed on a light ground and Seaglass Aqua is transparent, so both read closest to the jar here.
Buff and dark bodies52 Buff, Speckled Buff and Berlin Gray will warm and quieten everything on this shelf. The Ceramic Shop specifically warns that Electric Ash can run and darken on some stonewares.
On textureTidal Pool is the one to put on a carved pot. It breaks to a warm brown wherever the surface moves.

Common questions about Pro Series

How many Ceramic Shop glazes does The Clay Hole carry?

Four. Three from their Pro Series and one from their Sea Glass line.

What cone do they fire to?

Cone 6, which is where our glaze kilns run.

Are they food safe?

They are lead and cadmium free and conform to ASTM D-4236. The Ceramic Shop tells anyone producing dinnerware to test their own finished work.

Why does the maker talk about dipping?

Because that is what the line was formulated for. They thin it for spraying and suggest a brushing medium if you brush it. Ours are on the shelf as brush-on.

Which one should I use on a carved pot?

Tidal Pool. It breaks warm brown over texture, which is the effect it is known for.

Why is Seaglass Aqua here if it is not Pro Series?

Because it sits with them on our shelf. It is from The Ceramic Shop's Sea Glass line, which it describes as transparent and matte at once.

Test tile pots lined up on the glaze shelves at The Clay Hole

The Pro Series test tile pot

This family does not have a test tile pot. The colors and results come out close enough to what the book shows that a pot would not tell you much more, so work from the printed Glaze Bible and the tile above.

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.
