  1. hi LoneWolf, I have been doing Raku since 1 968 when Paul Soldner gave a workshop to local colleges in Phila. I also served on the technical staff for Ceramics Monthly focus on Raku. What type of research are you working on? Marcia
  2. ^6 for functional work. Low fire for experimenting with alternative firings. I am moving my soluble salts to ^6 in the near future with a glaze. Meanwhile, using a small amount of earthenware for a pit firing coming up in may with friends. Marcia
  3. Another note, while tapping the plaster you can use a spray bottle of diluted alcohol t break the surface tension of air bubbles as it is setting up. keep tapping until you don't have anymore bubbles surfacing. Marcia
  4. you can do it with a metal tine and 6 layers of toilet paper around the piece. Match the size of the can to fit the piece if possible. Bisque the piece to Cone 08. Don't fire much hotter than 950F.
  5. I use cobalt sulphate for the base and calcium chloride flakes for the dots.
  6. I use ball clay terra sig. I use a process I learned in Italy from Paola Parenetti. https://ceramicartsnetwork.org/daily/firing-techniques/raku-firing/super-quick-terra-sig-and-horsehair-and-feather-raku/
  7. https://alclayvirtual2021.com/?fbclid=IwAR20mRtcfayzzFnbw-BCQ4igFfyvySAgYPrRStbDyzqNX4ZqdR0sqq9LlOg 7 presenters will give a zoom prerecorded presentation and then be available for live Q and A.
  8. Marc Ward plumbed my burners. 2 tanks per burner. I fire with 2 burners on my large raku kiln. The two tanks share one regulator. No freezing. Inset my regular at 5 lbs pressure maximum. I added a photo I think in the next post. Marcia
  9. From the album: saggar, horse hair, feathers, foil saggars, Obvara

    obvara fired porcelain w/ a sodium silicate crackle surface
  10. experiments in alternative firing techniques, foil saggar firing, Obvara firing, ceramic saggar firing
  11. I had good sales too. I posted online sales twice and sold out.. I had to ship to both coasts but the sales were great. Marcia
  12. Thanks Pres. Just got it in the mail last week. Its is fun to look at a new pot every month and nice to be included. . Marcia
  13. One of my other teachers, Paula Winokur used porcelain on a large scale but she added Molochite to it. That is a porcelain grog. https://sculpturemagazine.art/paula-winokur-formative-landscapes/
  14. I throw porcelain and I use Coleman's Porcelain from Aardvark. It is a ^10 porcelain but I use it for alternative firing processes. For ^6 porcelain I have been using Lindsay's, Archie Bray Porcelain for ^6 and recently I tried Plainsmen ^6 Ice. It is expensive but I may have to get more because it is translucent and I love carving it. I learned large hand building from Bill Daley when I was in college. He built many large scale commissions using brickyard clay. World of difference from porcelain. He also fired his work at the brick yard on their conveyor kilns. To work very large the clay needs to have grog which allows thick clay to shrink more evenly and avoid cracking. It avoids warping too. Bill Daley http://www.williamdaley.net/about.html If you look up Carlo Zauli for Faenza, you will see many large scale works glazed white. The famous ceramics town, Faenza, is decorated with his large sculpture from the train station top downtown. Here are some examples.
