Not wrong, but there will be another crisis that will bring another wave.

Having some fun with Tomato reds on this unexpectedly snowy spring morning.

This is Lauren’s tomato, which you can find the recipe for on our Glazy page. It’s a really robust tomato red.

Correct! The fake shinos are all fe/sn. The AEs are up for debate, but that is what we are going to look at.

Playing around with some fake shinos. One of our students theorized that the broken cream/brown color may rely on bleed from an iron bearing clay. (It isn’t, more on that later). But we did test on this spotty stoneware from a client. We got this great effect where the iron nodules do bleed through

Anybody who screen prints can make their own of whatever images they want. We talk all about the chemistry of ceramic GITD here.

This one is copper and titanium. The broken crystallization is pretty alluring to me.

Thanks!
They are our Pro-Test test tiles and you can buy the master mold
at our website. Ceramicmaterialsworkshop.Com

Cone 6.

Thanks!

I’m getting out some good glaze test this week. I’m loving the double crystallization on this copper TiDi one.

I always say that I don’t have hobbies, just glazes all the time. But I do like cooking and baking.

So I made scones on this snowy Sunday, rather than tackle the snowplowing.

We’re premiering our newest video. Today @12:30 eastern on YouTube!

Join us here.

Working on the next Cracking the Kiln video for our YouTube channel! What do you all think? Is this my color???
Any guesses on what this video is going to be about?

Now I know there is Juliana Hatfield singing ElO
And my day is better for it.

Mornin’

The workshop faces east, so it makes the most of that low winter sun in the morning. Drawing us in, do get a few things done, after the kids are on the bus before things get crazy.

Lots of people hate the cold and the winter, but we love it. It’s just takes making the most of the light.

It has quite a thwock.

It’s clay body testing season, as we start to look at our first results from our clay bodies class.

This one from Biliana, shows so many options with the combinations of Gage Red-Lincoln Fire clay and Tile 6.

I talk about these in our next few posts.

I don’t think we have any in the pipeline

So smooooooooth

That’s wicked.

Mine are the ceramic crazed

We’re working on a video about it. The keycaps are glazed ceramics!

Nice to see all the new people,
Opening up Blue Sky this morning.

Looking at all the fun new glaze and clay body tests submitted over the weekend. While listening to Radiohead from Coachella 2017, this morning.

Hope everyone has a great week planned.

Mmmmmmmm. What I love about glazes is how much we can do with simplicity.
This once came out today and there is so much activity going on. Yet this glaze is so insanely simple, just silica, alumina, sodium calcium and cobalt for the color.

If you are going cone 10. You can find Zinc pinc on our Glazy page. Or look for a chrome tin red/pink

It depends. Water has an easy time getting in, but a very hard time escaping. As the glaze is vitrified by default. So water vapor gets trapped.

It’s a bit of a ship in a bottle situation. Once it’s in there it’s hard to get out.

No, it is a quality question. That’s the controversial part. FDA standards say that ware must be non-abstinent, for food usage. Of course that is often ignored, which leads to these problems.

Atmospheric is quite low. Well under 1%. But washing absorption can be quite high. Over 20% for bad clays

No, if the work has absorption, and has been washed it may act very differently. But it depends on the quality of the ware. (Low quality ceramics is a very controversial topic in our community.)

Ceramics cannot be 100% glazed.
As the glass that forms would stick to the kiln furniture. That exposed clay can very easily absorb water.
There are also cracks in some glazes known as crazing (or crackle) which are microscopic fissures down to the body, which water can seep though.

It seems that way, but ceramics (at least pottery) do not contain metals. They use oxides. Metallic bonds actually cannot function chemically in a ceramic matrix.
The reason why ceramics can get hot in a microwave. Is because some ceramics are porous, and thus absorb water inside the ware.
