    Camping, kayaking, family, travel, Art in general. I have a small studio in my garage. Two electric kilns, two wheels, wedging table etc. I am primarily interested in cone 6 Ox. but like to see what is going on at all ranges. Read about ceramics voraciously and love the feel of the clay and throwing. Have to admit that my greatest joy is in the making, not the glazing. That said I do mix my own glazes, some of my own formulas, some borrowed. Retired from teaching art, in 2009 after 36 years, taught ceramics 34 of those years.

  1. So Babs very recently asked: If you wanted to and had the means, which part of the process would you assign to an apprentice/assistant? For me it would be preliminary glazing and base clean up. Most of what I do, lately, starts with a base glaze with spray on over top from different angles to bring out the textures. Years ago when my wife and I were doing the Penn State festival, she would help by base glazing with a friend and do clean up before I sprayed on glazes and did brush work over that. As we don't have the big rushes anymore, I do everything. best, Pres
  2. I have had to fire lots of tile type projects by students over the years, as one of my projects involved tiles that demonstrated the use of 4 main forms of decoration-incising, added on clay, piercing and stamping. These tiles would be bisqued, first I would random stack with spaces between and then next layer over the layer below with spaces again between. This random stack all the way up on a full shelf at the bottom of the kiln would go up about 6-8" before I put in another layer with a double 1/2 shelf, and more tiles or pots above. Always fired slow, always to at least 11300 F. then faster up to ^06. The cool down was tricky as the kiln only had a setter, but you can block it up and fire down( I used a wire wrapped around the setter tab and drop bar to hold the setter up, then fired down slowly . . . manually. However you do it, cool down is very important. best, Pres
  3. Absorption

    I used 182 way back when I first started in my own studio. I found much the same problem. I have come to the point that now I only use clays that are ^-5-6 for that reason. I am now using their Hazelnut Brown, and a white stoneware-630 that is basically a ^6. I had wondered where your question came from, but it is quite clear now. Long range firing clays are problematic for funtional ware potters, especially if you are hoping to have pieces serviceable for many years. best, Pres
  4. Absorption

    Absorption is usually rated to the absorption of a clay body in the glaze fired state. Imagine an unglazed area of a an earthenware pot, that area would allow more water to be absorbed into the clay than a clay body that is fully vitrified at ^6 which would be slightly more than a body fired to ^9 or 10. At the same time, the porcelain body that vitrifies at ^6 is going to absorb less water than the stoneware at ^6. This is an over simplification, as many factors are involved including the vitrification of the body, and the clay type. There are ways of measuring absorption, as in soaking a piece of glaze fired unglazed clay in water and comparing the dry weight to the wet weight. Most of these things can be covered in books like Mastering Cone 6 glazes, or even by talking to your supplier. Big deal, maybe not, maybe so, but considering that a lot of wear and tear on functional pottery occurs from washing/dishwasher, the absorbance will effect the possibility of crazing in the glaze, thus making the pot less functional and somewhat unhygienic Again all an oversimplification, best, Pres
  5. Hi folks, Sorry I'm late but the PQotW Key for Week 25 is up.

  6. Oh Chris, what a weekend that was!. My ride in was worse than harrowing, but it was all worth it. best, Pres
  7. I remember a few years ago driving to a clay conference in NC through a freezing rain. . . 1/2 of sleet on the road, and trees with the same the next morning. The hotel didn't have power to check me in, slept on a couch in the lobby until early morning, then my room. Electric was scarce, but boy did I have a great time. Saw Chris Campbell there, and others. best, Pres
  8. Just posted PQotW 26, Enjoy!

  9. Week 26 In stoneware glazes, _____________ is often used as a matting agent giving some excellent opaque matt glazes. It is also very useful in helping to reduce crazing. calcium lime alkali zinc magnesia _______________ in glazes is due to the refraction and diffusion of light rays reflected from a surface that is minutely rough. Crystals Glossiness Mattness Durability A rust colored iron glaze-the rion oside crystals arte not visible to the naked eye. The name, _________, is Japanese for “persimmon”. Temmoku Tesha Shino Kaki The Mino area of Japan was responsible for four distinctive traditional styles of pottery, namely Oribe, Black Seto, Yellow Seto, and ___________ Temmoku Tesha Shino Kaki This weeks questions come from Stoneware Glazes, A Systematic Approach, by Ian Currie, c. 1985 second edition 1986, Bootstrap Pres, Queensland Australia. Note from Pres: I have had this book for many years, read it sporadically, as it is filled with many graphs and triaxial blend images that I have not understood until recently. It was written as a textbook, and is quite detailed in pursuit of the science of Stoneware glazes.
  10. Chilly asked in the question pool: Which is worse: Four days on the beach in the sunshine or Four days at Potter's camp in the rain. Interesting question for me, considering a couple of things. . . first off, I burn like fat wood when in the sun, red as a beet, blisters the whole nine. Use sunscreen it seems to be gone in minutes. Over the years the beach has been terrible for me. After the first two years of marriage where Summer vacation was the beach in NJ, I talked my wife into trying camping. We had and old canvas tent of my grand dads, borrowed stove, and an air mattress. It rained a lot, but we had a great time and ever since we camped mostly all over the east coast all the way up to Newfoundland and down to Florida, all in the Summer, no beaches thank you. So a camp for pottery even though raining, all for it, give me another two weeks for things to dry, or keep the heat up with lots of kiln heat like we used to have at PSU in my grad days. Throw in shorts or whatever best, Pres
  11. Marcia, Up at the top of your main screen there is a "create" button. Click there to "Gallery Image". Then select "members gallery" in the box. Should allow you to do what you want from there. best, Pres
  12. Folks I just copied two of Josephs tutorials to the Forum FAQ & Help Topics area. This should allow future users to find these excellent tutorials when needed without running a search.  This has been in  with approval of the Moderators and Administrators.

    Time to adjust to the changes, it is new for all of us, but if we work together, we'll all get through it.

  13. Joseph decided to go ahead and make a quick tutorial for adding status streams. These are exactly like the old ones, but much easier to read and respond to. The only difference is you have to go to your stream to see them instead of them being on the home page. The good news is reading them and responding to them is much easier. This tutorial is three steps and walks you through a different way of setting up streams. Step 1: Click the drop down button called My Activity Streams: You will see something like this. Click the big "CREATE NEW STREAM" button at the bottom. Step 2: This will open a page that looks like below. Name the stream "Status Updates". Then you only need to change two options which I have highlighted below: Step 3: At the bottom right corner you will see a button that says "Save Changes". I couldn't fit it in the screen shot, but its right below where this image cuts off on the right hand side. Step 4: You will now enjoy a feed that looks like this: It is big and beautiful and displays all the comments and updates and has much better formatting options. Enjoy! PM me if you have any problems and I will help as soon as I can. Pretty busy this weekend though. Also just a quick FYI. If you wanted to set one up for images, you can do the same thing, just instead of checking "Status Updates" on step two, select "Images" and name it something different like: Gallery Images
  14. REQUIRED Joseph wrote the following tutorial about modifying the forum to have some of the look of the old forum. Reposted here to make certain it was easy to find, and will be pinned to the top of the forum. best, Pres Admins: I wasn't sure where to post this. But this seems to be one of the major complaints of the forum is trying to find new content the way we did before. I tinkered around with the software for a bit and discovered you can setup your own activity streams and even set one of them to the default. Below is how to setup a content stream similar to before: 1. This is the default view. It is huge and displays the text and makes it hard to scroll through quickly. 2. Click Condensed: 3. Click Show me, and choose Content Items Only. 4. Now go to Content Types and choose Topics, the default will be All Content. Notice that this means you can create activity streams for status updates, if you want to see them exclusively and enjoyed them before. Decide on what you want to see in your status update. I personally only want to see Topics as I check the gallery manually and I have a status stream now. However choose the options you want. Then Click Apply. 5. Now lets change the time period. I don't want to see anytime updates. I want to see the updates since my last visit. So I choose this option: 6. Now our stream is completed. Lets save it. Notice the little save option appears above the condensed/expanded menu: 7. Now Enter a new name: I choose: Unread - Last visit. Then Press Create Stream! 8. Unfortunately it goes back to expanded view, so if you don't like expanded. Choose Condensed again: 9. Now set this as your default stream by clicking this tiny little icon! Notice now that it replaces the previous button that wasn't really useful with your custom stream. So now the old Unread button is gone and your new Unread - Last visit button is the default. If you want to create more activity streams like the status stream or image stream you can do the same thing, but avoid setting it as your default. You can access them all through this menu: Hope this helps everyone who has been having a hard time with the unread content button. It was driving me bonkers. If you decide you want the old one back. Just click the activity streams tab and choose the Unread one then click the default check button and it will go back to the original. Post any questions and I will try to help.
  15. Wedging Table Design...

    My wedging table is attached to the wall, with a brace system for a single front leg. I also added a fold down top to use when wedging white clays so that the Hazelnut will not contaminate. The hold down top uses two side boards to fit snuggly over the table itself. My table uses cement as a base with canvas top. Fold down is painted wood. Whole thing is steady as a rock. best, Pres
