Re: Digitry GB-1 controller for sale
It's the same programming as those "other" devices but seen from the time side. You enter elapsed time from start and then your target temp for that segment. One of my typical schedules reads 4:00 (hours:minutes), 1100 (temp F) 4:30, 1100 (30 minute hold) 5:00, 1470 5:15, 1475 (15 minute h...

Re: Digitry GB-1 controller for sale
I’m curious, how do you program AFAP on these controllers? My understanding is that you don't. You program how long it takes to get from one temperature to another. So there's no as fast as possible. AFAP on the Digitry is 1 minute. You're working with elapsed time from the start of the schedule.

Re: Iso-mag board
Another closely monitored private board, but Pete is more irascible than Brad. It's mostly blowing but there are a few active fusers. No anonymity there.

Re: Iso-mag board
Brad- One of my Canadian students uses it instead of VB- it's magnesium salt based, seems to be stronger than VB with less warpage. I asked on Pete's board, we'll see what comes up. I'll also call Jim Wiles (?) and see what he knows.

Anyone have experience with this stuff from Pyrotec (shelves, dams, molds, whatever)?

I wouldn't rely on thinfire for that. Do you need serious weight to dam your work?

Re: Hairline 'crack'
Bonnie- "bricks" sounds ominous, large masses of heat sink. Can't you use something smaller, like cut up shelves or other kiln furniture to dam your work?

Re: Hairline 'crack'
Bonnie- In my opinion those holds are completely unnecessary, as is any change in ramp up to 1000 (or so). You want to go slow enough to avoid thermal shock but that can occur anywhere along that ramp so going slower to 350 and then speeding up does nothing for you. What do the holds do? I'd like to...

Re: Hairline 'crack'
Bonnie- I hadn't understood how much difference in height you had. I'd do it at 100dph to process temp, no holds or changes on the way.

Re: Hairline 'crack'
I have issues with "120 to 350, hold 10, then 200 to 1250 hold 30"- I think it's mostly voodoo- but for glass less than 6mm thick you should be ok with that ramp. Did the glass get bonked (technical term) in any way before firing? I've healed cracks that hadn't separated by halving the ram...

Why are you looking in the kiln on the way up?Bonnie Rubinstein wrote:I noticed it ramping up- so it did anneal after. Maybe that is hopeful. But I may need to ‘disguise’ the line with some colored glass and that means re-firing. I wondered if that ensures success for healing, as well.

Re: Slumping issues
Harmless hyperbole. I was thinking of some of the meaningless schedules posted here, like the 10 minute hold at 350, then a change in ramp to 500 with another small hold, and so on. Why hold (and why there) at all for a simple slump? What's going to happen? If it's faith-based, that's a valid reason...

Re: Loose abrasives vs. bonded(pads,etc.)
I understood that any given abrasive grade contained a range; an 80 grit diamond lap pad included mesh sizes of 70 to 90, for example. Perhaps for something more exacting (like polishing lenses) a more precise grade is used?

Re: Slumping issues
200 dph to 1200, hold until slumped (look at it), then drop to 900 etc. No need for elaborate holds at 1100 etc.
Each mold will fill at a different time/temp.
Trying to flatten that piece will not give you joy. I'd give it away and start on the next one.

Re: Which properties makes blowing glass ? Engineering Cold Warm Thermoset Polymer Glass Blowing
We haven't had acrimony on this board for a long time- I'm not sure whether I'd rather see inactivity or conflict. Mustafa- This board is not the place you're looking for, and I don't think you'd get far on craftweb either. As Brad (the owner of this board) said, we're mostly interested in fusing gl...

Re: Choosing a wet tile saw
How much cutting of what sizes will you be doing? The bridge saw is not meant for or good for cutting small pieces- I'd get the regular sliding table 10" first. MK is reliable, the $300 Chinese copies are decent. If you can get a good used MK it's a great start; spend your money on the blade. L...
