#124385 Claystories 3 At Nceca

Posted by Marcia Selsor on Today, 09:37 AM

Joseph F.

His talk was great. I bought 2 of his bowls at the Red Lodge Clay center booth. I hope to go prospecting with him in the Pryor Mountains who the snow melts. I know them very well. We are both in Red Lodge.

Were you at his talk? He is a lot of fun.



#124043 Colemanite

Posted by Marcia Selsor on 19 March 2017 - 05:13 PM

I use gertsley borate as a sub for Colemanite. I bought a lot of that when it was going to disappear. I have no problems with it even though it has a lot of complaints against it.

#123977 Qotw: What Shape Do You Prefer?

Posted by Marcia Selsor on 18 March 2017 - 07:48 AM

I love throwing. Tea bowls, soup bowls, large pasta serving bowls, but my favorite form is the orb. I is like downhill skiing when your bringing the shoulder in for a small hole...focus focus focus!!

#123976 Can You Make A Plaster Mold Of Glass?

I have made molds of large glass convex light shades. I used vaseline and another time WD-40.

#123880 Improving Clay Plasticity

Posted by Marcia Selsor on 16 March 2017 - 06:54 PM

I have poked holes into clay using a dowel. Maybes many as 8 or 9 holes. Fill them with water.
Wrap them up and leave in a big plastic container. I repeat the process until the clay is what I want.

But sometimes the clay is stiff just because it may be a little thixotropic. It has a stiff outside surface.I throw it onto the floor on each side. Sometimes twice. That softens it up.It helps to slice it up and throw it onto a wedging table and slice several times. Wedge. This eliminates throwing clay with a tough surface in one places.

John Britt,s High fire Stoneware and Midrange books are both excellent. He is also very well prepared in his blogs and you tube clips. And he's a friend. Really enjoy his input into my thoughts.

#123514 Shinos

Posted by Marcia Selsor on 10 March 2017 - 09:07 AM

I'll need to be on the heavy side for clays. Also thinking of using burnt umber wash as a source for iron. I have some barnard here also. So far, in what I have read in the Golden Shino 53 page article pdf.
Wirt experiments splitting the clays and the feldspars and adding a dash of soda ash sound intriguing. because this is for ^12 and a wood firing, using a more matt with higher clay content version of the base seems necessary. I also have Crocus martis and 3 types of red iron, some black iron, some Apache clay remains from terra sig. Can't experiment too wildly because it isn't my kiln. Must proceed carefully.Very excited. Good Spring project.On top of preparing for a show and demo in Nye when a friend' s seasonal gallery opens. I am in heaven being here. And I have a clay supplier in town. Have visited 3 times so far. Mixed clay on a nice day wheeling my Soldner mixer into the sunshine. Warming up again this week.

#123496 Shinos

Posted by Marcia Selsor on 09 March 2017 - 10:26 PM

I am reading John Britt's latest writing on Shinos. Extremely well written and well explained. I am preparing for a wood firing opportunity and am looking at some possibilities. We have to glaze our work before we arrive. I am getting a great understanding of how shines have developed over the last 40 years. Our master, John Baymore has an awesome tea bowl with an unbelievable Shino crawl glaze. So, I am reading and considering how to adapt to wood firing by cutting back on the spar. Great reading for a snowy night.
John Britts 53 page dvd is called Golden Shino. Wonderful examples presented and history of people's glaze development from old friends like Malcom Davis and Frank Boyden. Just enjoying the read.


#123444 Silica Dust Exposure

Posted by Marcia Selsor on 08 March 2017 - 07:47 PM

I have been corrected by my friend John Baymore. .. Sub-micron dust particles can stay suspended in the air for 24 hours or more.
wet mopping is best.

#123429 Silica Dust Exposure

Posted by Marcia Selsor on 08 March 2017 - 02:53 PM

Clean studio practices is the best way to avoid silica dust. Sweep wearing a mask and do that at the end of the workday. then leave. Dust particles can remain airborne for 3 hours. Good idea not to stir up dust and hang around.

#123396 Qotw: How, When Or Why Did You Start With Working In Clay?

Posted by Marcia Selsor on 07 March 2017 - 10:49 PM

I was an Industrial Design major and took an elective in Ceramics. I found it much more satisfying to make actually functional objects than non-functional mock up models.

I can see that in your work , John.
Nice mature response in understanding oneself. I like that.
