This one has [Alberta Slip Clay + water, stick-blended into a slip] brushed on while still on the wheel. Clear Liner Glaze (from Mastering Cone 6 Glazes) liner, poured in at bone dry.
(Wait. This is the part where I defend myself by stating I really do know how to take proper photos of pottery. And I promise to prove it - at a later date.)
And this one was dipped into the same slip (so it's much thicker) when bone dry, with Bone glaze (also from MCSG) poured in at bone dry. This one has that tiny bit of soda on the right - I'd love to see how this slip looks thick like this but with lots of soda.
Oh hell, I don't know which slip this is. It's out in the shed, in my notes. But it did do something! Only where thin, though. Also brushed on when the cylinder was still wet.
And this one was just dry, but with the liner glaze.
If you were next to a port, you got hit. Otherwise ... Not so much.
I'm not too sure on the actual cone I reached in this firing, because one set was too close to the flame and the other was too high to bend. But it did seem more even than the first. I still have no idear what I'm doing with regards to reducing, so no clue on whether that was semi-even or not ...
Because I'm fairly insane, what I took away from this firing is: I need a different kiln. I want no part of this updraft system. I was a crossdraft, damn it! A want a single firebox! Big, so I can throw in lots of wood! And I want it now!
So I spent the next two months obsessing over such an animal. Then last month I brought one home. I'm hoping to move into its permanent home tomorrow ...
Oh! I feel so much better - as though I've actually learned a bit in the past few months of kiln-construction-information-cramming. Because my reaction to your suggestion, Mart, was, "But don't I need a bag wall to even out temp? If I were the flame in your drawing, I would just come in, turn left, and go straight out the flue - who needs to go all the way to the top?" and "I want to put wood / charcoal in this thing - I can't have the burners coming out holes in the bottom, getting all clogged up. Also, I'm going to have a hard enough time securing the things horizontally sans welder; I have no idea how I'd stand them upright."
I'm glad to see the bag wall only need be one brick high. And here I was going to go 13" high.
Just allow plenty of room around and combustable roofing and use metal falshing as you stack will be hot.-You can use hard or soft brick up to the roof -then hard brick in the weather or a stainless steel salvage pipe??
Is there a magic height at which I can switch to stainless steel pipe? (As I'm hoping it's less expensive than Canadian-price brick.)
