  1. Make yourself a 2 part "prototype" so you can be sure, those tools actually are improved if handle is thicker. I am sure it will feel nice when you pick it up but because your fingers are further apart you will lose accuracy in your movement. If you like to make those metal handles a bit softer, use heat-shrink tubing (used in electronics or by electricians).
  2. How much and what size grog you got there? No grog and >1.5 cm, is asking for trouble.
  3. Biglou13 asked for more information so, here we go: This vase is 15.7" high and 11" wide I used heavy grog (0.5-2mm) brownish stoneware clay. It's built from coil on the throwing wheel, I used black engobe. No glaze. Fired to 1200C

      Mart, I was asking you, weeks ago, how you did the blue on the tenmoku bowl. Now I know why I never got answers. My comment in your gallery didn't record. Great new vases! Evelyne

  10. What do you mean "spinning"? Wheel stands still and you have to run around it.
  11. has not set their status

  12. Red iron(III) oxide - Fe2O3 Black iron(II) oxide - FeO At high temperatures, Fe2O3 starts to break down so O and F take off and you are left with the FeO In oxidation, this is how you get those cool "oil spots" happening on the glaze where Fe2O3 is converting and free O drags F to the surface and leaves it there. Someone can probably get you more detailed description of the process.
  13. A stone cocoon with flower tentacles, surfacing through the soil in our tiny garden... Scary but beautiful Hand build, stone-ware clay, glazed and fired.
