#59258 Real-Time Kiln Advice (Kiln Curently Firing)

I do believe Curtis is coming back tomorrow to play "Fire the Kiln" with me.  


I even promised to make cookies.

#57538 Handles

Posted by Kristin_Gail on 28 April 2014 - 04:29 PM

To the original poster:
I, too, have been always unhappy with my handles, and they have always had some of the same issues as you - too thin at the top, too much smushing and working.

I've spent the past few days absolutely immersing myself in handles. Obsessing about it, really. Staring, studying, analyzing photos of handles I love. Watching gobs of videos. Reading so many words of advice.

And practicing. I only pulled maybe 50 handles in the past two days, but the ones near the end, the ones I just attached - they're the best handles I've ever made, in about seven years of trying. They're certainly nowhere near where they need to be - but they're the first I've ever made that don't make me angry!

It really can be done. And I really do think it's not just about practicing. Analyzing pots as I drifted off to sleep, dreaming about that perfect handle, visualizing it before I headed to the workshop ... All of it is working. It's working!

#56742 Real-Time Kiln Advice (Kiln Curently Firing)

Posted by Kristin_Gail on 16 April 2014 - 12:09 PM

This firing was relatively even in temp.  A range of Cone 5 starting to bend to Cone 6 almost done.  So, so, so much better than before.


But what I saw when I looked into the kiln while it was hot - the hard, fast flame going up from the bag wall, then further down the kiln the soft, licking flame only going in one spot - that's absolutely evident in the look of the pots.


Here's what I saw (not really to scale):




The bag wall is the same height as the second shelf - but the flame just snuck under it.  You might be able to see it from this photo:




All the shelves (B,C,D,F) but one (A) turned out white pots with hints of soda and light hints of flashing.  Like this:




I had some pots in there with Malcolm's shino, and every one of them came out stark white.


But the one shelf, A, that the flame touched, was dark, dark, and full of soda, colour.




The two larger mugs had nothing on them; the smaller, redder things had a slip.

The cones on this shelf were grey instead of white.  I can't find a reference but am guessing this has to do with amount of reduction?


I like dark.  I love the dark.  Am looking forward to learning, playing, tweaking more, in an effort to get all dark.

I don't know if something like this would satisfy your needs, but it might come in handy for someone else who finds this thread. It works with water, inside the house. Now we'll try it for real.

This is just a submersible pump with Pexpipe (whatever the hell that is) and a quarter-turn or ball valve on the end. All found items in our basement. We are hoarders, hear us roar.

#50841 First Firing Of This Here Electric-To-Propane/wood/soda Converted Kiln

Posted by Kristin_Gail on 23 January 2014 - 01:35 PM

Oh my, all the help I received here in the planning, purchasing, moving, building, firing of this thing!  Am I ever thankful for this place.


Thought I'd share just a bit here.  Details are on my blathering blog.


This is Big Anthony.  I think his chimney is too big.  But he works just fine.




I'm single-firing, and the process took about 21 hours, freezing cold to Cone Six.


He stalled at about 1950°F, and I fired the rest of the way with the addition of wood - which I'd planned to do, anyhow, for fun.  Just didn't realize I'd have to do it.


Learning is a process, right?  I completely screwed up the reduction I was hoping for; I only had four soda ports, located between the firebox and the shelves, and didn't get all of my soda introduced (near the end, the metal wand from the garden sprayer shot out of the sprayer, laying squarely in the firebox); and I accidentally crash-cooled it.  But I still got some great teaching results, considering this was the first time I'd ever fired any non-electric kiln beyond a couple test propane/soda kilns.








I learned a lot - ohmyword, so much - from this firing.  So much about firing this kiln, and firing kilns in general, about slips and glazes, placement of pots in the kiln, what my brain can and cannot compute on no sleep ...


In any event, it worked!  I'm forever thankful for all the help I received here.  It worked!

#45117 Kiln Shed Roof - Distance From Kiln

Posted by Kristin_Gail on 04 November 2013 - 05:05 PM

Hi Pazu -


You can see the details of the kiln in this thread.  After a few changes along the way, I've ended up with two MR-100 Venturi burners.  This is in my backyard, in town, so I do have electricity. 

#44455 Pics Of Electric To Propane / Soda Conversion

Posted by Kristin_Gail on 19 October 2013 - 11:26 PM

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 ...

#43254 A New Kiln Conversion Project: What Would You Do?

Posted by Kristin_Gail on 25 September 2013 - 08:02 PM

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.


Another question:



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.)
