  1. "Get the excess clay out before you raise..." expound please.. Apparently I am missing this info.

    Joseph: those who interested will respond, those who are not -won't. We "rabbit holers" like being down here. Every once in awhile the queen of hearts speaks.
  3. Okay Prez- now for a question. the biggest problem I am having is leaving too much clay in the base. I never seem to be able to pull all the clay up the cylinder. My wall thickness is getting very close, but I would "guess-a-mate" that I am leaving a third of my clay in the base.
  4. My bullet blender, I mix glazes as I use them. I dry sieve and then mix.
  5. NCECA

    Ron: think I better give you a heads up before you go. 1. When talking with potters at NCECA; when their eyes start glazing over when talking pottery: move away slowly. You are about to hear either very detailed explanation of their last firing or favorite glaze recipe. 2. Potters with white name tags only mean they have been cooking clay for over 30 years. 3. Leave your bill fold and credit cards at home: you could easily spend more than you make. 4. The old pottery guys who have been firing for decades all have beards...right Fred? 5. Those with no sense of humor should not read this post.

    Pieter: i have noticed when firing crystalline glazes that high percentages of cobalt would make the glaze boil. Although, the 25% zinc addition has to be considered as well. However, high copper additions always retained a smooth finish. Relative??? Just an observation. I have played with SiC in cone six red recipes. It seems to favor calcium and potash in a melt. i have had better success with SiC when I chemically reduce it beforehand: which I will not discuss here. Mr. baymore made a very logical point in another thread recently about the forum audience.
  7. NCECA

    Ron: i enjoyed attending NCECA in KC back in 2016. Lots to look at and take in. I did notice a mass gathering at the bar in the evening, with lots of pottery talk. I went specifically to meet with Ron Roy, but also had the pleasure of talking with Marcia Selsor and a few others. Spent several hours talking with an old wood firer from Maine: who was every bit as obsessed with wood firing as I am with clay. I had to bug out early because of business meetings; but wish I could have gotten in another day. If you can go, do it!!!!

    Nice piece. Like the softer hue and details. Local flowers?

    Can spot your work a mile away...a good thing.

    Lee: think you are finding that " voice" that you have been looking for.
  11. Highwater clay users

    Lady: weigh out EXACTLY 100 grams of wet clay on your scale. Then allow it to dry thoroughly. Throw it in the oven at 140 if you want to speed up the process. Then weigh the bone dry clay: if it weighs less than 75-78 grams, then way too much water was added when mixed. Have my doubts this is the problem, but it will eliminate one variable. Tom

  13. Thrown large

    Babs: rims are what I struggle with the most. Can never seem to get them straight. Maybe another few dozen or few hundred tries- will get it.
  14. Desert night to day

    Interesting departure from your previous works. Then again there has always been an artsy flair to your thrown pieces. Interesting the level of gold nuggets in the piece.
