Re: Flat Lap

Arrowmont in Tennessee had a potter's wheel that had been converted to a lap wheel. They had an iron disk laminated on top of the aluminum surface. Worked fine last time I was there, several years ago.

Re: Wait time

If you wait until it cools, you can slump or drape immediately if you wish.

Re: Coke & Corona Bottle Slump

Thanks for your input! Just curious, why 1,000 instead of 950? Because different glasses have different annealing temperatures. 950 is ok for art glasses like Bullseye and Spectrum, but 1000 is best for window and bottle glass. Also, sometimes I peek in (I can’t see much, it’s a tiny window) & ...

Re: Coke & Corona Bottle Slump

That schedule looks pretty much ok to me, except I would anneal bottles at 1000, not 950. About the only thing I can think of for you to try would be to see if you can get the slump at a slightly lower top temperature. That might help with the paint burning off, but my guess is that the paint is goi...

Re: Coke & Corona Bottle Slump

Many bottles use a paint that doesn't behave well in the kiln. Reds are especially problematical. If you give us the schedule you used we may be able to make some suggestions, but my guess is that changing the schedule won't do much -- it's just the nature of the paint used on the bottles themselves.

Re: annealling large panels

Bullseye would say about half that, or less. http://www.bullseyeglass.com/methods-id ... slabs.html

They don't have 9mm in their chart, so to be conservative go with 12mm or even 19mm, which are still below 12 hours.

No number needed. The email was mistaken.

But 40 is the right number.

Re: Kiln electrical question

You want it on the 60 amp. Don't install a 45 amp fuse, the fuse needs to be at least 10% (15% to 20% is better) higher than the what the kiln draws. So if a kiln draws 45 amps, a breaker of 60 amp is what you want.

We just get those inexpensive diamond point sets, which have a lot of different bits (sometimes called points or burrs). They're all made in China, I would imagine by somebody like Hans: https://www.hansinc.com/ https://www.harborfreight.com/diamond-point-rotary-bit-set-20-pc-69653.html https://www....

Re: Ceramaguard for carving?

I use it for carving all the time. You can carve it with any tool that will carve wood or a linoleum block. I carve more intricate designs with a CNC machine. After carving, you can kiln wash or use a sheet of thinfire over the Ceramaguard. The thinfire will hold together fine for the firing and wil...

Re: Light weight Kiln Shelf

I would only use Ceramaguard as a small shelf, not a large one. And it's actually best used to build small pieces on (square foot or less) and transport to the kiln, where I'd put them on a regular shelf or on LOTS of posts for support. It's not really feasible as a large kiln shelf, but it's easy t...

Mine's a decade old, so I'm sure they don't make that model anymore. I guess it's down to just checking reviews on some place like Amazon.

Re: WIFI monitoring of RTC 1000

Don't know of an attachment for the RTC1000, of course there are other controllers, but would be expensive. Here's what I did in a similar situation: bought a webcam and set it up so it pointed directly at the display on the controller. Then I could access the cam via the internet and check on the t...
