  1. If the saucers had been hotter, they would have been glossier ... is that so? They were alone at the bottom, actually maybe a wee bit cooler. Good point. Not bubbled, they are lovely and I love the contrast. I thought they would be the same colour as the stencilled patterns, but those got covered up. Only the bowl has about five small burst bubbles on the inside. 15' soak. Thanks for the medals! I'll get there one day.
  2. In real life the clay, engobe and glaze all fit together! Yay! But the same glaze (supposed to be satin) is very glossy over the engobe and matt/satin on the bare clay saucers. The ad-hoc glaze turned out rather opaque and hid the stencil work. Yes, there are some tiny bubbles. :-( Thanks again!
  3. Hi wonderful folks! After a long wait for a new kiln controller after mine died, I'm back with the engobes. My clay blend is lovely, so I have tested seven different engobes. For anyone interested, here are the results: First I made the sandwich strips as per Tony Hansen, with mixed results; Then I made several bowls and brushed on the engobes, each with a stencil and then, once bisque fired to 1,020°C, covered with a plain glossy transparent glaze. After bisque: They all look the same! My aim is not to have brush marks, but rather a nice smooth surface.
  4. I have it, but for some reason when I was tinkering with engobes his didn't work for me. I'll go back to it. Maybe my silly firing temperature. By the way, another autotelic resource was provided by a potter friend in France : https://artistryinaction.files.wordpress.com/2016/03/david_bayles_ted_orland_art_and_fear.pdf, and Grayson Perry's 'Playing to the Gallery'.
  5. Autotelic. Yes, exactly. As for the 16 years, there is the 10,000-hour theory.
  6. So true. The bright side is that I just LOVE throwing, and don't really know what to do with finished pots afterwards, so I have no problem with the long slow learning curve, all the more so that I read once that the moment of mastering a skill, however small, provides a shot of dopamine, so I'm always a bit high on my small aha-s! I won't have time to get really masterful like you folks, but every little progress is a boost. It's quite strange to have got hooked on pottery late in life, and strange that it should be such fun, such a pleasure, but hey, why question? I'll look at that link.
  7. Uh, no, there's another thing I didn't know about. It does go through the sieve with some coaxing. At the moment I'm following Tony Hansen's instructions in the excellent article you recommended. I have made clay/engobe sandwiches with four different engobes, to be fired tomorrow, including your latest suggestion. I even had the right ingredients. Although I got no simple answers here I have learnt a lot. Monet and Hokusai both figured that by the time they reached the age of 100 they should be doing some pretty good work...
  8. Thanks so much for all that input and patience. I'll try to put it all together and work something out.
  9. Let me recapitulate: I had an engobe formulated by Robin Hopper for cone 4-6 that used to work fine on my clay (1000°C bisque and 1120°C glaze) and under my glazes. Six months later the same batch of the same engobe is doing fairly well on new clay blends after bisque, (although it tends to fall off in places) but then under glaze it crawls like crazy and shows little bursts - so not bonding to clay. Glazes are OK. I have not been able to understand why the same workhorse engobe changed. I need an engobe that will bond at 1000°C and not crawl at 1120°C. I think I'll run some small t
  10. That wasn't 1120C, it was 1000 bisque firing.
  11. By the way, the bisque shrinkage of the new clay blend is 7%.
  12. I promise I didn't forget any ingredient. It was very gritty and hard to sieve through 80 mesh (the borax?), but all went through. I'm miffed too. The old engobe is bonded, just about, so the temperature was OK. How about my question. Any chance it will all sinter and bond in a glaze firing? Or will it be an absolute mess.
  13. Would it be the 45% calcined kaolin just sitting and staring at the clay?
  14. Next episode: bisque firing of pots made of my new blend, (lovely)decorated with stencils, and most with Glazenerd's engobe, one with the old faulty one, to compare. I sprayed it because it is totally unbrushable, even with gum arabic added. It looks great if untouched: (the mug on the left is the old engobe, which is likely to crawl after glazing unless it really likes this new clay blend). Result: Tom's engobe rubs right off! This is rubbed with a damp yellow sponge, as one does normally before glazing: :-( The question is : is there any chance that if I refrain fro
  15. I have no cones here, but I suspect it's between 01 and 1. I fire at that temperature because the clay I was using vitrified at 1,150°C. Stuck to the shelf, broke with glassy fracture. I managed to make glazes to fit, and the engobe was working nicely too. Now I have a lovely clay blend I'm throwing, and once it has been engobe-d, fired, glazed and fired again I'll see how everything fits together.
