Hey Anea- My schedule for a big slab 12"x10"x1" is 500dph to 1500, hold 30min afap to 960, hold 3hrs 60dph to 700, no hold kiln off to cool on its own to room temp Ive done about 10 of these with this schedule and it has worked fine. The set up starts out being about an inch and 3/4 h...

Fun piece! God knows I love color......and I also really like the dimension that you were able to achieve. Nice work

Thank you Lisa and being somewhat new at all of this if I decided to do the second firing what would be the schedule I would program in? or could I just use the preprogrammed one and when it hits 1400 would I just stop it and let it drop down naturally? Thank you again for your help! Jeri If it did...

For a piece that size, my slump schedule would be: 250dph to 1150, hold 20 minutes 9999dph to 960, hold 2 hrs 60 dph to 750, no hold Your pre programmed sch would probably work fine. I am not sure what temps are associated with slow, med and fast in your kiln, but I would choose a ramp that doesn't ...

Jeri- I have not had luck with the tear marks going away during the slump. But, I have refired pieces that have the tears on a new piece of thinfire up to 1400, no hold and gotten rid of them. it adds a firing, but worth it if you need the mark gone. The thinfire seems to maintain its integrity in t...

Don, I learned a bit about micas in a class. We airbrushed the mica on the whole surface of the base black glass and fired it, then washed the fired tile to remove all the loose mica, then applied the resist, sandblasted down to the black, removed the resist and refired to bring the blasted black ba...

Ann, I frequently have pieces hanging over the edge of my molds by up to 3/4" and they slump fine at 1150 without drooping. But, I am not sure how a side fire only kiln would do with that, maybe baffle around the piece to keep the edges from heating up too fast.

Ok, so I have a list of galleries that I would like to contact about my work. What now? What is the best way to approach them through the mail (none are near me). Send a color brochure, send a wholesale price list with pics of each piece, send a letter of interest.......or all of the above? I am los...

Hi Sadie

My MK-370 will cut up to 1 3/4ths", but I think that the MK-100 might go up to 3 or 3 1/2"?

Well, if that thing is as heavy as it looks, you will have arms like Schwarzenegger by mid summer! Thanks for the link.

Isnt that the point of learning a new technique......so that you can use it in your work??? I feel like everyone puts their unique slant on what they learn anyway, so the same technique can have many different incarnations depending on who is using it. For me, this goes for teaching as well. I did n...

emphasize the seams. cut 3/8" (thickness of back under the pieces + thickness of pieces) strips and use them on edge. put a pattern bar in the corners to make it really unusual. doing it this way you may not even need a back to the pattern pieces, and then they'll show on both sides of piece w...

When I make something like this I usually build a frame the same thickness as the central portion so the piece has a uniform thickness. Maybe this isn't the effect you want, but I've not had any thermal shock problems with it. Steve Well, I am looking for a continuous border with no seams and stack...

Assuming your pattern bar piece was about 1/4" thick, you had about 1/2" of glass there. But because of the uneven heating due to the large mass on top, the outside of the black glass started to expand at a much faster rate than the middle of the glass and blew it self apart. Lani's right,...

[quote="Lani McGregor"]Lisa, Sorry! Bummer. I agree with Tony on this one. It looks like a classic case of thermal shock on the way up. The center portion of the base glass is heavily insulated by the thick pattern bars while the outer edges are exposed to the heat from both top and side e...

Lisa, It's obvious that the glass blew up on the way up... but I see a piece of what looks like black irid blown to pieces and not a piece of clear. Is there another piece of glass there? What was the thickness of the base glass? Was the base larger than the pattern bar piece? If it was, that may h...

Well, I had a massive explosion apparently. I checked and rechecked the schedule and it was fine. Same schedule that I have used a bunch of times for the same type pieces. So, this is my question.......I noticed a pocket of air trapped in the clear base glass when I was assembling the piece in the k...

270/hr to 700 soak 15 AFAP to 1230 soak 15 AFAP to 1400 soak 15 300/hr to 1450 soak 30 AFAP to 960 soak 45 100/hr to 700 soak 1 min 200/hr to 200 and off I agree with Jerry that you could spend a bit more time at 960º. I would do at least an hour there. But in the past I have had trouble in the 96...

What was your firing schedule?

Jerry, that is gorgeous!!!!! Very, very elegant.
