#74291 Pitting

Posted by Marcia Selsor on Today, 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 Today, 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.

I fired ^6 reduction for 20 years and glazes were not distinguishable from ^10- tenmoku, copper reds, celadon, etc.Saves a lot of energy.
Some glazes will be different definitely. like the coppers.
I used different recipes for Ox. and reduction except for a nice matt

I think it is generous of Sherman to see how it goes. The forum is free for us but someone is paying to host it and the moderators are all volunteers. So thanks to all of them for their efforts. Good luck, high bridge. You have your work cut out for you.

#73694 Are You Started Into Your New Year Plan/program. Are You On Track?

Posted by Marcia Selsor on 20 January 2015 - 02:46 PM

so much for gross generalizations. There is ALWAYS some exception to the rule. I love Chip's outdoor work. He got a commission to do some work and workshops at the women's prison in Billings when I lived there (in Billings, not the prison). He used my kiln when he was in town rather than drive all the way back to Helena 530 miles RT.So the picture of Chip at the women's prison is after a successful workshop with inmates participating in the design and making of some parts of his outdoor installation there.

I'd like to see a gallery slot for the C"Challenge" rather than a members gallery. That way it would be easy to see many images on a screen. Going through pages of individual posts would be difficult to refer to pervious images.I think quarterly is also a good period of time. Many are busy working on other projects, etc.


#73089 Keeping Casserole Lids From Sticking During Glaze Firing

Posted by Marcia Selsor on 08 January 2015 - 05:21 PM

I add alumni Hydrate to my liquid wax on lid flanges and lips especially for porcelain. I use it on porcelain feet too. Porcelain can fuse easily. the alumina washes off after the firing.I use about 2 tsp in a pint of wax...about the as same as Tyler.


#72941 Any Recommendations For The Best Tools And Supplies Companies?

Posted by Marcia Selsor on 06 January 2015 - 12:11 AM

Welcome to the forum. Many supply companies sell similar things. Others sell their own clay brand. Location has much to do with getting supplies since shipping is a major cost. Look regionally for most of your needs.

#72723 Reflections And Resolutions?

Posted by Marcia Selsor on 01 January 2015 - 08:51 PM

Mugs take practice and experience with using. Use those you make and decide if the shape of the lip is comfortable. Is the handle comfortable. Is the glaze comfortable...tactile rating to the lips.
All these are important for a successful mug. Appearance is somewhat important but the mug is the most tactile pot we make...except maybe for a tea bowl.


#72370 Newbie Brent Cxc Pedal Help ...

Posted by Marcia Selsor on 23 December 2014 - 09:36 PM

you are talking about a price for a Brent cxc new for $1187. So $200 for a pedal doesn't seem so bad.
