Marcia Selsor Posted July 9, 2013 Report Share Posted July 9, 2013 I posted some of the pieces I fired over the past few days in my gallery. I am preparing some new work and techniques for this Fall in Minneapolis. Moving on today to other low fired possibilities. Link to comment Share on other sites More sharing options...

Pres Posted July 9, 2013 Report Share Posted July 9, 2013 Nice piece, I would like to see more. 30 years ago my district used an incinerator for burn garbage. I used to stuff large tin cans with small pieces, rags and sawdust to try to get a saggar effect. The pots were ^6 fired, then packed. We got some interesting effects, but nothing that approached what I thought acceptable. Link to comment Share on other sites More sharing options...
Kohaku Posted July 9, 2013 Report Share Posted July 9, 2013 Gorgeous. Reminds me of a moss agate. Love the form too. Have you posted any breakdown of your procedure- or is that proprietary? Link to comment Share on other sites More sharing options...

Marcia Selsor Posted July 9, 2013 Author Report Share Posted July 9, 2013 I am using thrown sag gars and fire in my raku kiln. I put sawdust , salt, and sprinkle with copper carb, or other nasty things like various salts and sulphates. I am using copper wire for the black lines. I just ordered some manganese salts (danger, danger, bad fumes) for water filters to see what that will do.This series also used Stellite alloy with cobalt , chrome, molybdenum, and tungsten. I got about 5 pounds of it a while ago. Sounded interesting for a pottery alchemist. Marcia Link to comment Share on other sites More sharing options...
Benzine Posted July 9, 2013 Report Share Posted July 9, 2013 So, if you fire them in your Raku kiln, are they fired as quickly as Raku? Link to comment Share on other sites More sharing options...
OffCenter Posted July 9, 2013 Report Share Posted July 9, 2013 I like the simple but elegant form that is prefect as a canvas for the painting you do with sawdust, copper wire and "other nasty things." More pictures needed. Jim Link to comment Share on other sites More sharing options...
Marcia Selsor Posted July 9, 2013 Author Report Share Posted July 9, 2013 I go a little slower so I don't crack the sag gars. I hold the temperature for 20 minutes at about 1600. The cycles takes about 1.5 hours. I let them cool to 500 before I open the kiln.Finished pieces are here: http://ceramicartsdaily.org/community/gallery/album/586-saggar-horse-hair-feathers/ Link to comment Share on other sites More sharing options...
OffCenter Posted July 9, 2013 Report Share Posted July 9, 2013 They're all nice but Saggar Collar 1 is my favorite. Link to comment Share on other sites More sharing options...

Pompots Posted July 9, 2013 Report Share Posted July 9, 2013 It looks great, i have done some saggars in my raku kiln too but all i got was black, need to test more. Link to comment Share on other sites More sharing options...
Marc McMillan Posted July 9, 2013 Report Share Posted July 9, 2013 Thanks for the inspiration Marcia. I've been doing more Ferric chloride/Aluminum saggar firing recently. I will have to do another clay saggar firing this weekend! Marc Link to comment Share on other sites More sharing options...
Marcia Selsor Posted July 9, 2013 Author Report Share Posted July 9, 2013 I find the possibilities endless.I am working on more color...green right now.Marc, how high do you go with the aluminum sag gars. My friend advises about 500 C or 950 F. Marcia Link to comment Share on other sites More sharing options...
Benzine Posted July 9, 2013 Report Share Posted July 9, 2013 Isn't there some type of gardening product (plant food or weed killer) that creates interesting effects in such firing? Link to comment Share on other sites More sharing options...
Pompots Posted July 9, 2013 Report Share Posted July 9, 2013 That would be "miracle grow" Benzine.... Link to comment Share on other sites More sharing options...
Marcia Selsor Posted July 10, 2013 Author Report Share Posted July 10, 2013 Miracle grow or Copper nitrate root killer. I bought 50 pounds of copper nitrate from an Ag supply store. It looks like Lapis, large brilliant blue crystals. Marcia Link to comment Share on other sites More sharing options...

Marcia Selsor Posted July 10, 2013 Author Report Share Posted July 10, 2013 Thanks Claypple. I am anxiously awaiting some new salts to try. Going for purple! Must make more pots. Meanwhile. I have 6 test clay bodies for an Ibvara firing. Haven't done it before but it looks amazing. Raku but with reduction in a solution similar to wallpaper paste. http://www.bing.com/videos/search?q=obvara+firing+youtube&view=detail&mid=68C27BB789538C203AF568C27BB789538C203AF5&first=0&FORM=NVPFVR&qpvt=obvara+firing+youtube Marcia Link to comment Share on other sites More sharing options...

I've never used it, in my own kiln, but in a college Art Ed class, one of my peers was doing a student taught lesson, involving saw dust firing in a garbage can. The copper nitrate was one of the things we added. Link to comment Share on other sites More sharing options...

Worse than just a regular raku session? Will I kill my nearby grape arbor? Do you end up with residue on your kiln, and is it an issue for regular raku? (Heaven forbid that Raku be unpredictable on any level)? Do your thrown saggers have any sort of a locking sill to make them in any way air-tight? This is all way off the reservation for me... but I'm very intrigued. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted July 10, 2013 Author Report Share Posted July 10, 2013 I make thrown sag gars out of raku clay. I used to make them with galleys for a tighter seal, but I find more flexibility if I don't. I can see a little flashing where the seal was not tight.There is not much out gassing. There is a little smell but not much. Residue stays inside the sag gars for the most part. I do this in a kiln shed 10 x 19 with large steel barn doors that I open up, across from an open door plus two exhaust fans near the high ceiling.I have not seen any residue on the fiber in my kiln.

My friend advises about 500 C or 950 F. Marcia Marcia - Greens. Awesome. I need to experiment more. When I do aluminum saggars I go to at least 1200F and sometimes 1300F. My quest is to understand how I can get yellows consistently. I love saggar firing...you can have an idea of what it will look like, but you never ever know! hmmm...my avatar disappeared...I'll have to reload.
