    uh, oh yeah....pottery. Gardening, guitar pickin' and wood working are among my interests. Hershey was my chocolate lab; he vanished in Feb 16. He's still in the photo and in my heart.
  1. It's going to be in the twenties by morning. Kiln has already shut off earlier this evening. This kiln is not programmable. Is there danger of it cooling off too fast after bisque firing? I guess I could turn it back on low, but I'm not sure if this is necessary. And that would certainly extend my firing time. How fast can a kiln cool down ( I don't mean by opening the lid) when the ambient temperature is frigid? ja
  2. By the time I get ready to trim my stoneware bowls, they are usually borderline-dry to too dry. That's ok, because I can trim and carve without distorting the shape. Sometimes I will lightly mist the surface that I am trimming, to soften things a bit. It can be a little messy, but it works. I would like to apply some slip to the ware, slip not engobe. But I'd rather do that after trimming. I'm wondering if slip can be applied to the green ware if I mist the ware first. It would be normal to apply the slip directly to wet green ware while it's still on the wheel, to get it to stick and stay. But would misting the dry ware make applying slip workable? Anyone done this? ja

    Building A Hydraulic Extruder

    I have a gasoline 26-ton splitter and have been thinking along the same lines. These things aren't known for their lightning speed, and their power is amazing. Holy cow ! The extrusions should be amazing. Dual-purposing my log splitter is a definite maybe and New Years resolution for 2017, preceded only by the intention of eliminating procrastination. Vibration might be an issue, but might create some interesting effects, too. Ear plugs. Huh? EAR PLUGS. Yep. ja
  4. I inherited some Black Raven clay (Kickwheel, now Stone Mountain). So I threw and bisqued some things. I had made up some 20x5 (Tony Hansen) glazes which glossed up and fit very well. But the black swallowed most of the color. I don't think adding an enormous amount of oxides or stains is going to fix this, but have thought of creating an engobe or underglaze, and applying this to the ware. I haven't found much on diy mixtures; one I found suggested ball milling a stain, which I have read is a "no-no", because it can release encapsulated toxins. All of my work is Cone 6, and I like to stay reasonably "food safe." Anyone have any thoughts or recipes for ^6 engobe or underglaze that might save these pieces from target practice? Thanks, ja

    1823 E Olympic Electric Raku Kiln

    Mercury displacement, new to me. Just looked it up. Very interesting!

    Are you using contactors or SCR's?

    1823 E Olympic Electric Raku Kiln

    You can always buy a stand alone digital controller for the other kiln depending on how many amps it needs. I'm building a controller for one now to handle 60amps. I'd appreciate any info on diy controller. Good luck with yours. 60 amps would cover any kiln I have. ja

    1823 E Olympic Electric Raku Kiln

    A friend of mine needed some carpentry work done on her studio and hired someone. She said if I would help the other carpenter dude she would give me her kilns. One was this electric raku kiln, which can be used as a regular kiln (up to ^8) and the other was a old paragon high fire electric that looks pretty clean and sound inside. I went for it. Glad I did. j
  9. I just acquired a 10-year-old, Olympic raku kiln that has only been fired three times. The body of the kiln raises off the base with a hand-winch and cable. I've never done raku and plan to use it to fire cone 6 stoneware and other clay. The kiln has a 6-key controller (never used one before). Pretty Pumped! This rig lets you set up and align all of your shelves, posts and ware, and then lower the kiln down on them. Anyone ever used on of these? ja

    Help: Air Bubbles!

    I just put my pug mill into operation. It is not de-airing, so I expected to find bubbles in the pugged clay. They are not there when I slice the pug multiple times. But sometimes, after I open on the wheel, I find one or two bubbles, usually after I attempt to make the bottom of what I am throwing, flat. Bubble or bubbles appear in the very low part of the sides of my bowls. This is consistent with some of the posts I've just read here. I have been cutting clay from the mill and then slamming it down on the wheel, thus trapping air under the clay(maybe). It centers and works beautifully, except for those occasional bubbles. Thanks for all the great information on this! john a.

    Pug Mills :)

    WOW! I just cleaned up my old Bluebird 650 pug mill and filled it up with left-over stoneware. I am amazed! The tech at Bluebird said it would pug about a thousand pounds per hour. I put the clay in the hopper, mash it down, and out comes a 4 1/4 pug. It doesn't seem to be a speedy process, but it comes out almost as fast as it goes in. Holy cow! I cut off a round with a wire, put it on the wheel, center, cone up and down, and it sure feels a lot better than cutting from a block and making balls. I have made many slices to check for air bubbles, and they pretty much do not appear to be there. I don't understand that, as this is probably a 25-30 year-old, non-deairing mill. Not saying I never get any bubbles; sometimes I think I introduce some small ones while throwing. I think I'll always have some of those, no matter how much I machine-pug or hand-wedge. But I had no idea that this mill would work this well. A thousand pounds per hour? Well maybe on a good day, but I don't even have a thousand pounds of clay, and I don't think I'd want to work that hard just to prove it. But what a thrill to be able to recycle all that junk clay! Now when I screw up a pot on the wheel, it doesn't seem like such a big deal. Worth the $150 I spent, and the trip from north Georgia to New York to pick it up. I'd do it again, in a light-second.
  13. I will run some test tiles later. That should be telling. It was a pleasant surprise that I hope I can duplicate.
  14. Well, it sho is pretty! Having trouble getting my old nikon L3 to make nice with my computer. Sorry about lack of pix.
