I tried it (long ago) with some Urob mottles and it was a complete failure- mottles disappeared, colors went blah, glass devitrified and some actually crumbled.
However- it would take you no time at all to put some scraps in your kiln and find out for yourself.

Don- build one.

...and for us.

If you're talking about rounding the edge of a disk or bowl by rotating it perpendicularly to the pad then yes, the surface contact is minimal and you could indeed do a very large piece on a very small diamond pad. If you're trying to get a flat rim on a bowl by pressing it open side down on the pad...

Dana- You'd be surprised at the area that you're working on the disk. For a ½ " thick bowl with an outside diameter of 10" and an inside one of 9" (nominally), to get that flat lip you're grinding more than 15 square inches of glass.

Does anyone use a lap grinder with center feed water to grind/polish the edge of a piece larger than the radius of the disc? For example, a 10" bowl on a 12" disc. yes, all the time. Are there risks, issues or problems with this approach? (I'm aware of the hand lapping with loose grit opt...

Higher temp and/or more time at the top.

There's a bucket-sized collector that can go between the cabinet and the vacuum- anyone recommend it?

Hmm, patience I must learn...
and forbearance also.

You're welcome.
Merry Christmas.

You could get a plumber in but I think an ice-maker setup (from your hardware store) that taps in to your cold water pipes will take care of supply to your machines. If you need more volume then you could go the garden hose route. For waste- the WBS is easiest since it uses little water- put a bucke...

It's not the few extra minutes. My issue is with schedules that have no rationale for the processes and become gospel.
It's also about understanding and simplifying the whole process.

Looks like the glass got through the kilnwash at a few points. Add a strip of fiber paper around the perimeter for insurance. Cutting the ring was a good idea. That schedule is fiction (who wrote it?)- why the holds for 3:06, 3:04? What practical difference is there between 80 dph ramp and 75 dph fo...

How thick the glass?
Which glass?

Shawn- I can't talk about SS grades, I don't know what mine are, but I've used SS as thin as 18g and as thick as ⅛" from slump temps to 1500F (briefly) and gotten no spalling ever. Over time and repeated firings the stuff does begin to oxidize but all that means is more maintenance- light sandb...

Too fast. Too hot.
Please tell us where you got that schedule.

Les- Case them with clear in the kiln first, then you'll have the coating when you have them blown out.

Don- I don't think Cynthia's intent was to equate sealing a glass surface with an oil, wax, silicone, urethane etc. with applying a patina to bronze. It's similar to waxing finished metals (after patina) or woodwork (after staining) to protect it. I don't see the harm in doing so and disclosing the ...

Only once, but there was that cork-backed metal ruler. And a small brush...
