#41376 First Test Pieces - Glaze Not Glossy

Posted by OffCenter on 24 August 2013 - 06:20 PM

Thanks for weighing in, everyone. :)

 

Looks like I need to try Cone 6. 

 

I'm a little confused regarding the cooling though. One person suggested I cool faster, while others are suggesting ways to cool slower (with the fiber blanket).  :unsure:

 

It always depends on the glaze. The person who suggested cooling faster is probably right if you're trying to get glossy clear. For some glazes, especially mattes, slow cooling is better. For some, super slow cooling is best. Some potters use incredibly complicated holds and ramp downs for cooling saturated iron glazes. The only way to find out what works best is by testing.

#41099 I'm In Ceramics Monthly Again, Yay!

I got my copy of CM yesterday. Your piece is wonderful. Congratulations again. In the review, I like the part where the reviewer picked up a hair dryer to see the breeze ripple through your "Straddling the 405" and was stopped by a guard.

 

BTW, John Baymore has a nice piece in this issue, too.

#41095 Why Earthenware?

Posted by OffCenter on 20 August 2013 - 09:07 AM

Hi folks,

Stoneware: it's stronger, less porous and far more commonly referenced as a potting material than earthenware - so why would i want to use an earthenware clay body?

When I saw the above nonsense, I thought Oh crap, here we go again, I gotta dig out the Pinnell MOR test results, etc., but thanks to Trina and Marcia I can go pick muscadines instead.

For those of you who don't want to support Hobby Lobby, other craft stores stock Mold Builder Liquid Latex and Amazon has it for a couple of bucks less than Hobby Lobby.

 

Jim

Why not support Hobby Lobby, because their prices are ridiculous?

 

 

It's political so I won't go into it here.

When I was a kid I liked to throw clay balls at other kids--we didn't get much snow. Other than that, I've never really cared that much for clay.

#40753 Bisque Firing Cone 6 Stoneware

Posted by OffCenter on 13 August 2013 - 04:34 PM

Don't apologize for questions! Most of us love them because it gives us a chance to show off how knowledgeable we are even if we have to fake it. There's no set cone to bisque to. I use a lot of different clays (commercial, mixed from scratch, dug) and usually just go to cone 012-010 simply because that's plenty high enough to give the bisqueware handling strength, and just right for absorbing glazes. The only reason I bisque higher (08) is to give very large bowls a little more handling strength and dug clay and Lizella Red to cone 04 to burn out organics. So for a nice, clean commercial clay, bisque to 010 or to be extra cautious bisque it to 08-06. Don't bisque higher than 08-06 unless you have bloating problems with the clay. Firing higher than you have to is a waste of time, energy and wear on the kiln.

 

As for glaze firing. Don't fire higher than cone 6. I don't think you have to worry about it if you sometimes hit 7 when aiming for 6 but don't push it higher than that.

#40589 Need Advice, Too Many Options For Firing!

Posted by OffCenter on 10 August 2013 - 07:39 AM

This post may seem that I'm shilling for Susan Schumpert, a potter who sells Olympic kilns, but I promise that's not the case!  She retails Olympic kilns that have been refurbished or that have scratches and dents and such.  She also sells new kilns at 30% off retail.  I found her two years ago through a pottery site that lists items for sale by potters, pottersweb.net. She posts a list of available kilns a couple of times a year, I think. She was really helpful to me when I went looking for my first kiln, although I ended up buying locally because I needed to have the kiln delivered and set up for me (and the local seller was the only retailer who offered that service).  I don't know what kilns are available at the moment, but you can Google her name to get contact info.

 

Basically, this is a way for Olympic to sell kilns without upsetting dealers and a great way to get a good deal on a kiln.

#40175 Materials to press into clay for random texture

Posted by OffCenter on 05 August 2013 - 10:37 AM

So, should I worry or not?

 

No. Saggers in elect kilns do almost nothing to prevent the heavy carbon smoke from getting on the elements, so sagger firing would be more damaging to the elements than any material added to clay because, most likely, you're burning a lot more material in a sagger or saggers than the stuff you stick into clay. But, with that said, I don't think even firing two or three saggers with a couple of pounds of sawdust or coffee grounds in them is very harmful to the elements. I've been doing it for years.
