Benzine

End of year firing were always fun. Especially those that had mixed loads of bisque and glaze when firing ^06.

Perhaps an extended candling to insure dryness?

glazenerd, that goes without saying when you teach ceramics to kids. Heavy thick walled areas is not unusual, no matter how hard you try to get them to understand the problems with overweight poorly constructed ware.

Nice. So exciting!

Congrats, Poppa!

Had quite a bit of time in the hospital. On the plus side, I came up with a few pages of concept sketches for wares.

Takes a lot of CMC, so I make my own.

Thanks for the responses all. I went with a little bit of Epsom salt and gum solution. Initial test went well. Brushed on pretty evenly. I may have to tinker a bit more, but it's a start.

Scotty would have pushed her to Warp 12 and held on for dear life.

Yep, it survived. After shutting off the kiln, I kept checking the peep for moisture. When none was detectable, I started it back up. No issues. There were no spots over 1/2" thick.

Good job on the steam check. I always use the hand at the peep hole to check for moisture during bisque, and glaze firings.

I did a firing last night, and gave it a shot, with some pre-testing and precautions. It was SPECTACULAR-ly disappointing... The oil barely burned. Definitely no explosions and sizzled like bacon hitting a hot skillet. No real splatter to speak of. I've had worse from throwing frozen veggies into a skillet.

LOL Well that's good to know!!

Yeah, not dangerous, but also not worth the time. I thought the oil would burn, and give some nice carbon effects. It really didn't. And since the glaze went from the oxidation of the kiln, to an environment that provided neither oxygen or carbon, the glaze didn't really change. It doesn't look bad, just nothing amazing.

''Tis the season

''Tis the season

Babs, I tried something similar a couple years ago, but scooped out the "guts" first, and dried the pumpkin a bit. Some interesting results. This time, I just cut the top off the pumpkin, and put the hot ware directly into the pumpkin guts, seeds and all. The pumpkin top seals nicely to keep the air out. Pretty interesting result. I'll post photos later.

Yes...but it works great!

I am attaching shelf liner to the backs, so they don't skid, and so that the students only know to use on side. Hopefully they work as well as I plan...

I used a few stainless screws to set mine: just enough to hold it it place.

did you simply place the lid over the bottom of the tumbler? Then pour?

Yes indeed. I didn't want to bother waxing them, or spend the time wiping off the excess. I saw a lid sitting there, and I gave it a shot. If I wanted the end of the glaze to be further up, I would scoot the lid further to the side I was pouring on.

Why not just dip upside down? Were you using a different liner glaze?

I need to bisque and raku fire but the heat is forbidding.

Yeah, your heat is definitely worse that it is here. Walking outside yesterday, was like jumping into a pool. Instantly drenched.

so Benzine is score no more different from the magic water?

The gum in the recipe by Old Lady is Gum Arabic, can't see why CMC won't work

Babs. Score No More is Gum, Custer Feldspar and the clay body. So it's more of modified slip. Whereas the magic water is mainly water with the soda ash and sodium silicate.
