In Topic: Tea Pots Cracking Violently

07 October 2014 - 04:39 PM

I'm inclined to say glaze fit problems, judging by the pattern of the cracks and when they are occurring.

Try throwing a handful of bowls with equivalent thickness and composition, then doing the standard post-firing freeze / boil / freeze process....

In Topic: White Spots On Bisque-Fired Brown Clay

I have this happen sometimes with darker clay bodies. As was said above, it's usually scumming; but it can also be dust / detritus loose in the kiln from pieces from a white body, or even kiln wash if you're unlucky.

 

I'd say about 80% of the time, I can fix it with some vigorous sanding in the bisque stage. Obviously take proper precautions to not breath the dust from sanding.

 

If this doesn't work, then your best bet is to cover it up. It can absolutely show in the final firing.

I have so many questions to ask about burners and air supply! But am going to wait until I get in the kiln books I ordered (Monday). Hopefully I can answer some or all of them myself.

Neil, yes the inflated rubber wheels DID seem odd to me... I'd much rather have a set of hard castors or something shielded from the heat somehow.

 

And I'm not worried about size. Smaller is actually probably better for me in a city studio (to a point). But at $6700 you could definitely be looking at 12-ish cu ft front-loaders... If I could house them.

 

And that's a good note about the chimney's bagwall too. I was curious about that. We've all seen kiln shelves warp over time, but I thought it was more from gravity while they are hot (a sagging effect). I didn't know they'd warp in a vertical position. Good to know!

It is definitely on the spendy side.... But still cheaper than front-loading stationary downdrafts (though smaller). For sure paying a premium.

 

And yes Wyndham, I'm still considering doing my own electric to gas conversion... I've watched all of Simon Leech's videos on it, and read every thread I could find about it here and on Clayart.

 

I also ordered Nils Lou's book (Art of Firing) and Mel Jacobson's book (21st Century Kilns) and plan to devour them.

 

But, at the end of the day, I'm still 100% new to working on kilns. Never cut a brick, have no tools for it, etc... If I had to pay a premium for something like this, it might be worth it to me.
