In Topic: Pottery Cracking In Glaze Firing

17 April 2014 - 03:29 PM

Hard to tell for sure, but it looks from the photo like they cracked once the glaze was already hardened... When cracks occur in the middle of the firing, the edges of the crack are usually more rounded as the melted glaze's surface tension rounds out corners.

 

I'm guessing it's a cooling dunt as well. Even slightly faster cooling on a thin form, that may have a little bit of glaze tension, can cause dunts.

Who told you it was OK to fire on a bamboo floor? Every kiln spec / manufacturer's recommendation I've ever seen says only to fire on a fire-resistant substrate. Concrete, tile, or fire-resistant boards of some sort.

Might also be worth firing a few unglazed cups to see how the body holds up under the same conditions, without a glaze.

In Topic: Runny "fern" Glaze?

The posting actually calls out the glaze as a fake ash.

Look up Hannah's Fake Ash on google, it's very similar. My guess is the same (or essentially so) base recipe with some tweaks on the colorants.

For what it's worth, I think that's a really cool inclusion. Many people ADD bits of metal to their pieces specifically to get looks like that.

 

Imperfect can be pretty :-)
