Custer Chips?

18 August 2014 - 09:51 PM

I bisqued/calcined, come custer chips, in order to make smaller bits for inclusion in clay body for woodfire.
In an attempt to make a shigariki like clay.


There are some dirty bits in the feldspar chips


Some of these bits melted/ sintered at bisque temp, melting to a porcelain bowl


What are these dirty bits?
how do remove these dark bits?

I imagined the feldspar chips would have been cleaner.

Tumbler/ Ball Mill

I have some feldspar chips and granite, that is a bit large for inclusions in clay. I need smaller bits. I'm thinking a ball mill/tumbler to make easy work of this. What media in tumbler/mill should I use?

Just made recipe

2500 epk
2500 glomax
5000 alumina
4250 h20
20 Darvan

It's settling like mad.

Only what is alumina. That is how bag is labeled. I'm guessing I had wrong one

Alumina hydrate vs alumina oxide........

At this point I may "floc". To suspend???!!!!

Nice color.

I plan on testing....

Keeping in mind work heat.

When a piece gets refired, does it become more mature? Does absorption level decrease, does a glaze become more "glassy"

I'm sure there is a difference if you doubled the time at final temp. But as a refire you just doubled the time at fired temp.

I've seen subtle differences in glaze. But never thought about the body.

Is there risk of over firing/ slumping if my body is close to limit?

I'll run tests.....
