In Topic: Digging Up Yo' Own Clay...halp?

Yesterday, 11:01 PM

I had a colleague give me some blue green clay, from her property.  It had quite a bit of debris in it.  I slaked it down, and ran it through a screen, like Marcia suggested.

 

It was easy enough to work with, and I even through some things with it.  When fired, it turned golden yellow.  It survived to Cone 04 well enough.  But it was weak at that temperature.  The test tile I made, was about a quarter inch thick.  I could snap it in half, once bisqued.

 

I never took it beyond 04.  But in college, one of my classmates brought in a similar clay.  The instructor fired it to at least Cone 6.  It melted at that temperature.  

 

I actually still have some of it left.  I may use it again for something.


In Topic: Qotw: Do You Have A Story For Us, Featuring Tom Roberts (Aka Tjr) ?

Yesterday, 10:50 PM

Like Babs, I am just getting caught up on this.  In fact, she is the person, who alerted me to it.

 

I can't say I have a really good TJR story, but like others have mentioned, he sent me several private messages.  He was always more than willing to offer advice and assistance to anyone.  I could always depend on him for some good classroom stories.

 

Between his postings here and work as a teacher, his contributions will not doubt be missed.


In Topic: Large Flat Pieces Cracking During Glaze Firing

One thing I like about Raku, which is very evident in your video Marcia, is as the glazes cool, once the kiln is open, it's like watching a photo develop.  You start to see where different glazes were applied, as they begin to develop their color.

I don't know why firing them would cause them to disintegrate?  The only thing that should cause a greenware piece to come apart in such a way, would be moisture.  And in that case, it's usually only a lot of moisture in a small amount of time.  Like if you soaked bone dry greenware in water, or even wrapped it in sopping wet towels.

You should be able to repair the piece. There are numerous recipes to make a greenware mender. A bsic recipe involves corn syrup, vinegar, paper pulp and clay powder from whatever the rest of the ware is made from. The last ingredient woukd be your hang up, unless you know what type of clay the wares are made from.

If you can figure that out, you should easily be able to repair and fire the wares.
