Tony: So now I am more confused. What I am thinking about doing is using the ss ring as dam to contain the glass from a pot melt. The sides would be straight up and down, and that would be the idea - to have 90 degree sides. Lots and lots of kiln wash?? I don't think fiber paper would work in this s...

Have any of you tried firing a blank inside a stainless steel ring with just kiln wash on the ring? Is it best to always line it with fiber paper?

I was thinking about using a SS ring to do a pot melt into as a dam. Maybe it would be better to use a fiber board ring?

so many questions...

I should always check this board at least once a week - this is too much fun! I love the idea. So for me, opposite would be small, represtational, and non-functional...I'm in. Avery - I may need help before your class....! Annah This whole project reminds me of a quote I have up in my studio: "...

A friend of mine has a Gryphon bandsaw and he had tons of problems with it for the longest time - to the pont that he was putting the blade on backwards (can you believe that??) - just to get the *^%$ thing to stay on. He finally called the company and they said that they had had problems with that ...

Charlie: The steel is all 1/4". I talked to the builder the other day about using grating under the fire brick (though he may have been thinking about the expanded steel stuff - not as heavy as you are talking about) - he thought it might move too and then rasp the bottom of the fire bricks off...

Well, well. I haven't been online, because I have been dealing with what showed up with the firings...turns out it wasn't the firing schedules that was making my pieces curve. No, no. The support structure on the bottom of the kiln (1/4" thick I-beam steel) warped. Yep. warped up 3/8" in t...

Charlie: Well, we'll see what happens tonight when I open it up. I did go a little slower on the cooldown, just in case the bottom of the piece is cooling faster than the top. My tech guy moved the thermocouples yesterday so that they are more evenly placed, with one in the center down low near the ...

Charlie - you were close when you made the assumption about the kiln design - the only difference is that I am not firing on boards - I laid out a fiber blanket right on the bricks and am firing on that. I wonder if the bottom is cooling too fast. Other than that, your assumptions were pretty close....

Did you change anything other than the schedule? How far are the edges of the glass from the wall elements? How far is the surface of the glass from the ceiling elements? How many wall elements are there? How many ceiling elements? Can you raise your shelf so that it is above the wall elements witho...

OK. I ran the firing last night. The pieces look good, with nice crisp lines, and they are NOT FLAT. They are bowed in the middle by about 3/8". My theories are: 1. Since the edges that are down, are the ones nearest the side elements, there is some uneven heating happening in the kiln. 2. My t...

OK, I'll go program the controller and get it going. Whew! I really want to take a workshop on firing schedules for top-fire kilns. Anyone out there going to teach one??

Where are the baffles located in the finished box?? On the top? Or is it wider than the compressor and they are on the sides?? Sorry - I got confused by the photos.

Great idea, btw. I hate wearing earplugs - I DO it, but I hate it. They bug me...

Rosanna:

somehow I thought that the soak at 1200 had to be on the way down. Is that wrong? I can do it the other way...

250 dph to 1200 hold 20 min
afap to 1450 hold 1 hr
afap to 1040 hold 1 hr
100 dph to 740 hold 30 min
end

like that??

Ok, you all...I will check the archives about the tin coating and research where to get a uv light. Re the firing schedule: this is what I'm thinking of doing, based on ALL the excellent feedback I have been getting: 250 dph to 1450 hold 1 hr afap to 1200 hold 20 min afap to 1040 hold 1 hr 100 dph t...

I want to get a really crisp line with fiber paper below. Do you think I will get that at 1435? I'm game, I just want a good, deep impression.

Hmmm. I got the 1510 from an old thread I found on the board as I was looking for firing schedules for float. I doubt that I would have to go that hot - I don't generally. All the variables that we deal with make algebra look easy! So: What if I do this: 250 dph to 1450 hold 1 hour afap dph to 1040 ...

Bert: So when Brock says to go to 1510 degrees, I shouldn't? I could take it to a lower temp and hold it longer...will it devit? (The piece is warped, not bubbled, by the way - about 1/2" tall in the center...) I am holding off the next firing until I feel like I have SOME understanding of what...
