  1. Porcelain Workshops

    Hi Everyone, I would like to inform you of future workshops that I will present . The workshop in Sunnyvale California is postponed until October. I will confirm the exact date later. The Arvada Ceramic Arts guild host a compact hand-son workshop on August 8-9 On Sunday night the Castle Clay group will host a slide presentation a slideshow presentation, describing my background, inspirations, motivations etc. including past and current work as well as a discussion of influences from my upbringing in South Africa. We will follow that up talking specifically about the business side of art; how to get into shows, exhibits and galleries; relationships with gallery owners, photography and presentation to get into the same, developing a body of work, marketing, etc. In September 2015 I will do another hands-on workshop at the John C Campbell Folk School. The next online workshops are available for registration again. This time we are opening "Wheel thrown Porcelain Dinnerware" and "Hand building Porcelain" Both classes will run from July 27 until September 3rd, with further viewing of material until October 2nd. In 2016 I will travel to Europe to present workshops there. Details TBA. Information about these workshops are available on www.porcelainbyAntoinette.com
  2. Is it possible that particularly virulent bacteria continued to respire in the drying slipware? if yes, would that show bubbles burst at the surface visible to me before firing, or not, I wonder? I made my own porcelain paper clay slip with porcelain powder, dispex, tissue and water. It's worked before but I left this one and it stank. following instructions from tutor I added a bit of bleach but the bleach didn't completely kill whatever it was, not totally. It was grey in colour. I poured vessels, they looked fine (but the smell and grey colour lingered until they were totally dry). Biscuit showed no signs of any problems. But stoneware temp and they've come out looking really vile, absolutely completely covered in small irregular bumps. I've broken them open and it's clear air pockets near to the surface predominantly. I can't see that this was clumped paper fibre as most of the gas holes are smooth in shape. It was a well mixed and as bubble-free as a liquid as I would usually have it. Therefore any burnt off paper could have escaped through usual channels. HOwever, if the paper gas could escape then why not this gas (if that's what it was)? Is this just a matter of something going too hot? many thanks.
  3. I have been trying to find an answer to this online with no result. If I were to mix two kinds of premixed casting slip with different shrinkage rates, what would happen? Would the shrinkage average out or would a mushroom cloud obliterate my dad's kiln shed? We want to try mixing Laguna Oriental Pearl (shrinkage 14%) with Lagina White Stoneware (shrinkage 10%). I know that stoneware/porcelain blends exist as a clay form, but I'm not sure how it works with slip.
  4. Pale blue teapot

    From the album newer work

    Simple teapot, with a silky white glaze over a blue slip.
  5. Pink to purple bowl

    From the album newer work

    The glaze is the standard silky white crystalline glaze I've been using a lot lately. The center of the bowl was sprayed with a pale green crystalline glaze to define the texture of the fluted pattern carved lightly into the porcelain. For unknown reasons, this sprayed on glaze fumed the white rim of the bowl to an almost fluorescent pink, and crystallized pink flowed down and collected in the center of the bowl
  6. Hi guys, I'm looking for anything that I can add to my porcelain slip (cone 10) that will result in a fine surface texture. This could be fairly uniform almost sandpaper-y, to just varied and rough. Like below: http://www.walkerceramics.com.au/images/Compressed%20images/BRT%201280%20R%20054.jpg http://claymotion.com.au/wp-content/uploads/2013/05/brtsample.jpg Not necessarily the colors I"m after, more just the texture, but open to any suggestions. Any thoughts would be great!

  9. Yunomi with combed blue and green slips

    From the album newer work

    This yunomi was dipped in both green and blue slips and then quickly combed to expose both. It may be excessively bright, but I like it because it's lively. Same white satin glaze.
  10. Cloud Blue mug

    From the album newer work

    Another piece with sprayed-on slip and satin white.
  11. Mug with green slip and blue ash

    From the album newer work

    My second favorite piece from the last firing, This was sprayed with a green vitreous slip, and glazed with white satin matte, followed by a spray of blue ash glaze.
  12. Yunomi with multiple slips

    From the album newer work

    This is probably my favorite piece from the last firing. The yunomi was sprayed with a vitreous green slip and then a more refractory lavender slip. It was glazed in my current favorite glaze, a titanium satin matte. Somehow this treatment resulted in a soft gray with tiny flecks of many colors, green, blue, lavender... and with a mysterious pink flush on one side.
  13. I read somewhere not to use stilts with porcelain (high fire) as the wire will meld into the body...but no instruction as to what to use instead (alumina sand??) What are some other ways to keep the glazed pieces off the shelf? Thanks in advance
  14. Three mise en place bowls

    From the album newer work

    These three porcelain mise en place bowls are glazed with a clear deep blue and oversprayed with an active rutile glaze. I like these because they remind me a little of salt-glazed work.
  15. Five mise en place bowls

    From the album newer work

    Five mise en place bowls, celadonish glaze, in porcelain, fired to Cone 8. Approximately 5 inches in diameter and 2 inches tall.
  16. Pale green ash-glazed yunomis

    From the album newer work

    These porcelain yunomis are fluted and glazed with a pale green ash glaze on the exterior, and a clear glaze on the interior, overlaid with ash glaze a distance down from the rim.
  17. I just returned from the North Carolina Potters Conference. Our presenters were three established potters from Japan ... just amazing to watch as they worked. There were many lessons learned but one excited all the throwers so I thought I would share. From Fuku Fukumoto ... Google her images and enjoy the Artwork. She centers and cones her porcelain, then cuts it off the wheel, turns it upside down and centers and cones again. (many thought this reversed the twist that the first centering and coning process put into the clay) She just said it further compacts the porcelain making it easier to throw. The other presenters agreed that they knew many porcelain throwers who did this but did not do it themselves. I am not a big time thrower so I do not have an opinion ... also, their porcelain is made from stone and is so grog free it is like butter ... 180 mesh as opposed to our 60 or so. NOTE : see my later post ... on realizing their clay was stone based, so this could be why it works for them. I have to admit if I was a thrower I would definitely try it just to see what happens, but it also could be a useless extra step for clay.
