    Finished work
  2. From the album: 2017

    Base glaze in the top left. Across the top is (4.2 Tin Oxide : 0.15 Chrome Oxide premix) in 2, 4, 6, 8% Down is Cobalt carbonate in 0.25, 0.5, 0.75, 1% These 17 test are all done with mixing just 4 batches of 100 grams of glaze!
  3. Take it apart, clean it out, find nothing unusual, put it back together, find you have an extra piece or screw, and see if it works again.
  4. Made an army of test tiles. Just to dead soliders in the end?

      Just pawns, each one seeking glory.

      Soldiers will always be lost in the glaze battle.

  5. are all transparent glazes Celadon? > No, technically Celadon glazes are low-iron glazes which turn green to blue in reduction at high temperatures. But today the word seems to be "any lightly colored mostly transparent glaze". Anyways, fake Celadon glazes still have wonderful texture enhancing qualities that generally sensitive to the thickness of glaze application. Especially on horizontal pieces.

    ZNO levels

    Wow. About 26.4% should make a nice balance of flowers and open space.
  8. I feel a fair amount of pottery technical knowledge is rather... inbred? Of course, most people who get mechanical engineering degrees don't end up in pottery. If I was currently taking mechanical engineering materials science classes, I am sure I would make or find pottery-specific problems to solve. But today I don't really wish to revisit it and just guess. Incidentally, my ∆6 firing schedule which I arrived at independently finishes 150°C/hr to 1100 100°C/hr to 1220, 5 minute hold down80°C/hr to 960 (ish, I think, I don't really remember) and maybe a 30 minute hold. I haven't
  9. Did you ever get "Materials Science and Engineering: An Introduction 6th Edition"? The used cost for this older edition is... ~$10 on Amazon. I am not sure how it will help you, but I still think it will. I wasn't into pottery when I was taking this class but I recall the book being pretty good.

    Flower of Life pattern. Cobalt oxide under a turquoise crackle glaze. I love the way the cobalt bleeds a little near the bottom but stays crisp near the top. 11.5" tall. ∆6 oxidation Priceless.
  11. Australia has a different voltage (and frequency but that shouldn't matter for a motor). I never saw Brent wheels in New Zealand and would not be surprised if they only make a 110-120V model. There should be a plate somewhere on the motor that lists the required inputs and maximum amps and such. I have an Australian (Venco) pugmill. To make it work I needed a voltage converter. I predict you will need one too.

    A Hug

    From the album: 2017

    A Hug between two of my favorite glazes. I love anthropomorphic pots and this piece captures that feeling very well.

    Oh, she isn't a particular person.

    She's a keeper! ∆6 oxidation
  15. It was well thought out. The only thing on wheels is the plaster for reclaiming clay. Everything flows. All it needs is another 1000 sq ft (which would double the space!) :-) Oh, an more windows. There is only one that faces south. And more sinks. And... ah... it is a good home and I am happy with the space.

    Work spaces are important too!

    A year into the dream.
  18. I had a relay fail after 72 firings. Sigh, I had put off getting spare parts to my next order.

      I had to do this also. I also found out that Paragon will no longer stock parts for my Duncan kiln. I got extra parts. Expense I could do without at this time. Best wishes.

      Ohhhh NUUUUUU, geez! That's so lame! D: Sorry, buddy!

  19. Most of my Brent wheels are raised 4" (4x4) and most of the Shimpo wheels are raised 1.5" (2x4). This has been what is comfortable for the majority of my students. What is comfortable for me: sitting at the wheel (with my left foot on a 3" height from two 2x4s) and my left elbow on my thigh I should be able to put my hand on the wheel head and have my forearm just a little above the whee head. If the forearm is hitting, it will give me rug burn. If I am too high up my wrist will hurt.

    ∆6 oxidation Brush wax with cobalt oxide was applied to make the river so this decorative large bowl has a slight texture to it.

    They would also be magical with the right crystal glaze...
  22. A continuation that arose from Challenge #6
