#76729 How Are You Surviving This Winter Season?

Posted by Marcia Selsor on Today, 10:11 AM

I like that delivery man. I had a pallet clay delivered and the driver unloaded the pallet with a forklift and left. I moved it all with a dollie but 200# at a time. I guess I'm a woos (sp?). My husband , the theoretical astrophysicist says he went into theory to avoid mass. I am on my own.



#76726 Studio Musings

Posted by Marcia Selsor on Today, 10:01 AM

I love being in my studio. I like it even better when I re-organize it and get rid of the clutter. Sometimes I let that build up when I am really focused on something. The rest of the studio, kiln shed , etc. get neglected. I once had a student say that throwing was like downhill skiing. You can't stop concentrating or you wipe out. I think the focusing is the key. That develops into a soothing meditation. Almost compelling. Maybe not almost. 



#76290 Nceca 2015 Providence, Ri?

Cowboy boots are more Texan but not where I live. Here there are more chic Latinas. I would say the boots would be in Central Texas to Oklahoma. Women wore them in Montana but usually for ranching or working  and not as a fashion statement


Just come as you are. It is a Potters Conference and fairly casual although some may dress up for receptions and the Friday night dance.


#76277 What Causes Glaze/clay 'tide Mark'?

Posted by Marcia Selsor on 27 February 2015 - 09:09 AM

I think it is where the soluble chemicals travel through the clay from the glaze.

I am on Facebook and there are several excellent sites there, Ceramics Contemporanea LCG is fabulous. International ceramics is another.



#75994 Weight/size Charts?

Posted by Marcia Selsor on 23 February 2015 - 11:59 AM

I agree, Mark. Good functional ware needs to be sturdy. My thrown porcelain "dust collectors" are thin and not meant to be used for functions purposes. The 8 place setting dinner set I made last year was made from 175 pounds of clay for 32 piece set with some extra pieces..

a place setting was 2 plates, a bowl and a mug. I had a lot of trimming scraps  that I used for paper clay. 



#75818 Alternative Firing Workshop S.padre Is. Art Space 2/18/2015

Posted by Marcia Selsor on 20 February 2015 - 11:10 AM

Here are some pictures and results of the participants  from the workshop. Went to the Palms' .St Pier for late lunch since we fired the last pieces around 2. We fired the two kilns for a total of 11 firings for Obvara, horse hair and feathers, saggar and raku.


Coconut Shrimp was great. The Shrimp nachos looked good too.



I think the Palm Street Pier was having a wake in the bar. I whole line of oldsters shuffled by doing the "locomotion" and a live singer was singing Amazing Grace when we left. Wild place! At our friend, Pete's funeral, the Shriners played Amazing Grace on Kazoos. There wasn't a straight face in the house!

#75343 Glaze Spraying With A

Posted by Marcia Selsor on 12 February 2015 - 06:24 PM

I didn't like that one from Harbor Freight because I use an air brush sometimes and this is only one setting for the air pressure and no way to change to a different spray gun. I have a Geil gravity feed spray gun plus an EZ spray gun with 4 plastic jars.. So I replaced my compressor with a used Powerful from Sears which is whay I had been using for decades. I needed to replace the Powerful because it was noisy and overheating.

If I only used the HVLP from Harbor Freight for glazing it would have been fine. It all depends on what you need to do with it.



#75320 An Observation

Posted by Marcia Selsor on 12 February 2015 - 01:06 PM

sometimes I realize how little I know, how much I want to know and how time is short. But I do know that..as John says, when students think they know everything and then find out they don't.


#75299 Potash And Soda Feldspars - Are They Interchangable?

Posted by Marcia Selsor on 12 February 2015 - 09:25 AM

Pot ash and soda ash can affect the glaze colorants differently  as well. 


#75196 Cone 6 Firing Schedule For Updraft West Coast Kiln

Posted by Marcia Selsor on 11 February 2015 - 08:51 AM

I fired a an updraft Olsen with 14 burners when I taught for a year at UTB. I followed the kiln log which started with the damper about 1/3 open and half the burners on. (the outside ring of burners on low ). 2 hours later turned on the inner ring of burners on low. Increased the pressure hourly until about 25% open on natural gas gauge . It took about 14 hours for ^10 and 11 hours for ^6. I did a body reduction at 09-04 and glaze reduction at ^8 or ^5 depending  by shutting the dampers down to about 1/8th open for about 45 minutes each. The air disc on all the burners were rusted solid , so no adjustment there. Hope this helps. Not the same but you get the idea. This kiln was big. This photo was ^6. Attached File  olsen2May12.jpg   41KB   0 downloads


#74760 Amaco Chalks?

Posted by Marcia Selsor on 03 February 2015 - 02:50 PM

I have used the chalks in my classes at the university. Students liked drawing with them. too much in one area can cause crawling. Mostly good work came out of their use.

#74620 Does Anyone Else...

I can bring a can of Bag balm for you to NCECA.

See you then. And take care of your hands.



#74291 Pitting

Posted by Marcia Selsor on 28 January 2015 - 01:11 PM

could be several things
could be not fired enough or not soaked
could be the bisque was too fast or not hot enough,
could be the bisque soaked it up top fast which could be resolved by smoothing it when the glaze was dry.

Those are my guesses.


#74264 Moving Down The Pyrometer To Cone 5/6

Posted by Marcia Selsor on 28 January 2015 - 08:29 AM

I do change them to 100% for my recipe box. This one was changed from ^9 to ^6 by adding 10% Gerstley Borate.
To get it to 100 divide all the ingredient portions by 113.Don't change the addition of the colorants. This glaze is very receptive to color variations. Great for experiment for new colors.
I just got this from one of my ^6 recipe pages on my computer. Somewhere on another page it has been converted. I didn't notice it had not been converted when I posted it.

Thanks Old lady for catching my typo.
