Ceramic Materials Workshop @ceramicmaterials.bsky.social · 25/03/2025Not wrong, but there will be another crisis that will bring another wave. 010
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 25/03/2025Having 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. #tomato #red #glaze #pottery 0170
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 09/03/2025Correct! The fake shinos are all fe/sn. The AEs are up for debate, but that is what we are going to look at. 010
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 09/03/2025Playing 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 1150
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/03/2025Anybody who screen prints can make their own of whatever images they want. We talk all about the chemistry of ceramic GITD here. youtu.be/k1p1_4cQWSo?...youtu.beGlow Up | How to make a glow in the dark glaze | Ceramic Materials WorkshopYouTube video by Ceramic Materials Workshop 050
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 21/02/2025This one is copper and titanium. The broken crystallization is pretty alluring to me. 1250
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 21/02/2025Thanks! They are our Pro-Test test tiles and you can buy the master mold at our website. Ceramicmaterialsworkshop.Com 010
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 21/02/2025I’m getting out some good glaze test this week. I’m loving the double crystallization on this copper TiDi one. 2250
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 16/02/2025I 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. 0180
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 12/02/2025We’re premiering our newest video. Today @12:30 eastern on YouTube!

Ceramic Materials Workshop @ceramicmaterials.bsky.social · 11/02/2025Working 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? 0120
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 06/02/2025Now I know there is Juliana Hatfield singing ElO And my day is better for it. 110
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 30/01/2025Mornin’ 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. 0331
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 28/01/2025It’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. 0381
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 28/01/2025I talk about these in our next few posts. 120
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 28/01/2025I don’t think we have any in the pipeline 000
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 27/01/2025That’s wicked. Mine are the ceramic crazed 010
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 27/01/2025We’re working on a video about it. The keycaps are glazed ceramics! 150
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 27/01/2025Nice 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. 4950
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 24/01/2025Mmmmmmmm. 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. 1381
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 06/01/2025If you are going cone 10. You can find Zinc pinc on our Glazy page. Or look for a chrome tin red/pink 000
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024It 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. 010
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024No, 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 110
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024No, 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.) 110
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024Ceramics 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. 110
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024It 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. 110
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024This image is Clay Art Center's English Grolleg body and it has the same curve as the dark Redstone body. 180
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024This is L.O.I. or "burnout" for Laguna WC420- Redstone, which is a dark body. We are tracking weight loss of the sample with temperature, and you can see that the vast majority of the loss happens before cone 020. And the last image is Clay Art Center's English Grolleg body and it has the same curve 050
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024Seriously you guys. There is nothing burning out past cone 08. And there is no such thing as a "clean bisque", by bisquing hotter. Anything that does decompose leaves the body primarily by cone 020 and realisitically by cone 012. 190
Ceramic Materials Workshop @ceramicmaterials.bsky.social · 04/12/2024Firing a hotter bisque does not do what the community thinks it does. 5200
