#82665 Drying Bowls - Rim Up Or Rim Down

Posted by Marcia Selsor on 28 May 2015 - 07:15 AM

I flip mine too. Helps to dry evenly.I guess it could help prevent warping if they are drying in a draft.



#82631 Raku - When Is It Safe For The Second Piece?

Posted by Marcia Selsor on 27 May 2015 - 08:44 PM

I put my slabs in as soon as I have finished unloading the previous batch. I use coils to ease the shock of a hot shelf.


#82466 Large Flat Pieces Cracking During Glaze Firing

Posted by Marcia Selsor on 26 May 2015 - 06:51 AM

I make sun ray patterns with the coils for the foot to rest on. they can move but mainly they let moisture escape.

I fire my flat slabs upright leaning against stacked shelves or bricks.


#81765 Clean Merge Line.

Posted by Marcia Selsor on 16 May 2015 - 11:34 AM

Hamada and Dave Shaner used the Bray liquid wax.In fact, I think it was developed for Hamada while he was there.  Probably any of the modern liquid waxes would work. Cover the first glaze with the wax where you want it. Allow the wax to dry. Then wash the first glaze away from the edge of the wax line. Then you can apply the second glaze. Clean the glaze off the dried wax.

#81689 Glaze Testing

Posted by Marcia Selsor on 15 May 2015 - 11:30 AM

A hazard message is not reassuring when the bowl could last beyond one owner. Use the glaze on the outside but not for contact with food.I have a glaze similar. It looks great on carved vases. (outside of vase). Have you done a slice of lemon test on it? I think you would see a noticeable change in color. You can use strontium carbonate to sub for barium but not 1:1. 

I'd have to look it up. 








#80794 What Discourages You And How Do You Get Over It?

Posted by Marcia Selsor on 05 May 2015 - 06:52 AM

Funny you should ask this. I had a disastrous Saturday trying to fire the rest of my raku pieces. In my large kiln I fired a slab that had been buried away in some shelves. I put it in with my large slabs all firing on edge. The older slab cracked knocking over all the pieces and pushing the pyrometer out of the kiln where it broke part of the sleeve. I didn't notice that. So I shut off the kiln and moved a burner to my other kiln and fired that up with smaller pieces. Approaching 1800 F the pyrometer stopped working. I shut that off. 

I have 7 underfired slabs now. And some warped. So it goes. I am firing up some freshly mixed glazes today. The kiln is already loaded.I threw out the ones not worth refiring.

At the Seattle NCECA Marge Levy presented a video to the whole audience "Keep on Keeping on" . If I can find it, I'll post it.

Marge is my friend from 60s in college. We're both still keepin' on. It is a funny but encouraging video.

Just remember you are not doing this for the people who walk away from your show. You are doing this for you...and as Paul says, enjoy the journey. 

Best to you.,

#80546 Heat Resistant Gloves

Posted by Marcia Selsor on 01 May 2015 - 09:09 PM

this is a video showing the use of heat resistant gloves . I use this because it is easier to pick up large slabs this way than with tongs.


Not sure this will transfer from Facebook.


#80289 Is Your Art Influenced By Ancient Works?

Posted by Marcia Selsor on 28 April 2015 - 01:09 PM

Great question , Evelyne. 

I have been making art for over 50 years, studying from museums, drawing, observing and working in clay for 49 years. Over that time period, many things have influenced me. I will list a few.

In the 1960s I greatly admired the political commentaries of gerry Williams. Several were on display in Newport during NCECA. In 1973,I saw a great show on Discoveries in China since Mao at the Smithsonian in 1974 or 75. Many of the potters who also saw the show agreed on one outstanding pot...a small spittoon of porcelain with a beautiful pale bluish celadon glaze. It was a simple low orb form topped with a very wide flared upper half. This did influence my work during the 70s. I also feel the vitality of early cave drawings influenced my work as far as studying animal movement for my raku pieces as well as an ancient Chinese sculpture of a leaping horse from the Ferghana valley. It is where the Chinese captured their War Horses. 

Other pieces that have inspired me or created great admiration for the artisanship are pieces from South America, particularly Chimu and Nasca Pottery. I greatly admire the tiled ceramics of the Silk Road: Maddarssahs, mosques and mausoleums. And there are the structures of the Alhambra in Spain. 

I admire the work the Arts and Crafts Movement including Adelaide Robineau, Sarah Irvine and Taxilte Doat. And I am a big fan of the naturalist Bernard Pallissy. I saw a wonderful show of his in Paris during the IAC meeting in 2012. 

I fell in love with Romanesque imagery in ancient churches when I traveled the back roads of Spain interviewing potters in the 80s.. I was often near the Pilgrimage to Santiago. That imagery was conveyed in my Architectural installations: Marking the Millennium in the 1990s; one millennium later after the original images from the Revelations of St. John. 

Now I seek my own way experimenting with simple processes. I appreciate low tech and simplicity.

There are a great many things that have had some influence on my thinking if not directly on the outcome of my work.here is a link to what was a thread on my top five potters.





#80240 Cone Ten

Posted by Marcia Selsor on 28 April 2015 - 07:09 AM

Bisque firing is usually to ^06. Sometimes lower if working with Terra sig.  Sometimes a little higher wif working with porcelain in fragile shapes. But the general bisque temperature is ^06. Are you working alone or do you have access to others who could help you along? This is an elementary question. I am wondering where you'll be firing to ^10. That is hot so take precautions with your kiln set up.




#80015 Risks Of Putting Kiln In Garage

I would make sure your insurance company knows it is there.



#79989 Cost Or Running A Kiln .

Posted by Marcia Selsor on 24 April 2015 - 09:25 AM

That seems extremely high. Did you fire to ^10?  2300 F.

How large is the kiln?

What is the cost per KWH?

When I worked at a coop we always wrote down the starting and ending numbers on the electric meter.

Then multiple the price of a KWH to figure the cost of the firing.

#79893 When Do You Know To Start Regular Firing Of Your Kiln?

Posted by Marcia Selsor on 22 April 2015 - 06:09 PM

If you are talking about moisture as Chris asked, I have used a mirror or a jar by the cracked lid to see if there is still moisture coming out of the kiln.
