Re: Go and stop and go? Or just go?

Now that's a concept I had never thought of. Uneven cooling means you should cool more quickly? Is it really true? Personally I think that the holds in the canned programs are just there so that everything looks more the same. Rate, set point, hold. If every segment has numbers in 3 places it makes ...

Re: Assistance with color options....

If you want deep pinks and fuschias then forget the system 96 and use some Bullseye. The fuschia is dark in sheet glass but you can layer your frit as thick as you need. There is also cranberry 1311, and several pinks in the 1800 series. Also shades of coral and pinky oranges. The colours are richer...

Re: Bead Door on Kiln

I haven't seen the bead door on this kiln, but if it has a space at the bottom (most do) then block it with fiber paper. The only problem might be if the door is fiber and the kiln is brick, then that side might heat a little differently. The window shouldn't really have much effect, it's pretty sma...

Re: Which glue is best for glass to glass on sushi plates?

Hmm, everyone is back to silicone these days? I have never thought that it had much adhesion - you can pull the dried stuff off glass with your fingers. I have always liked the UV setting glues like Lumifix or Triolyse. However they work best with clear glass that lets the UV light through. Triolyse...

Re: Compatibility

My compatibility failures have usually been on a third firing, so I would certainly be suspicious. Can you not do a test with polarized lenses on the suspicious party?

Re: pate de verre kiln

After firing a couple of castings, I have decided that my Skutt Clamshell isn't going to be enough for casting. As well as being top fired, I thought it wasn't going to be deep enough at 13.5". However when I start looking at kilns, there aren't very many that are deeper than that until you get...

Re: glue question...suggestions GREATLY appreciated

I suspect that if you could see glue, then it didn't fill all the space between the layers. You really need a lot of excess glue to completely fill a space, regardless of the type of glue. Also, silicone is usually watertight, but it is fairly thick so not so easy to spread out, there will be a lot ...

Re: Nuggets

You can also buy glass rods and just nip them, but the dot size is limited by the rod size, so I prefer to make my own. Oh, but the size of the dot depends on how thick you nip your pieces. Also, bear in mind when you are firing squares to make circles, that there is a big difference between Bullse...

Re: Crack in finished bowl

You are right, sitting in the sun in a window can start a crack. I have always attributed this to compatibility; as the glass heats up, the differences in the expansion rate starts a crack. It is a strange looking crack, however, very straight, but only felt on the surface not on the bottom, so prob...

Re: Q: Annealing around trapped air

I would think that as the glass cooled, the pressure inside the bubble would be considerably reduced. So I guess if the air pocket is large, it could create some mechanical stress. I don't know if this has anything to do with annealing however. I guess there is no way you can vent the bubble afterwa...

Re: Bear Facts

Thanks so much for the help. How do you hold it all together while you are pouring your wax? It seems like a couple of elastic bands aren't going to manage this one. And while we were cleaning up the garage the other day, I found a couple of old small soldering irons that I spirited away into my stu...

Re: Bear Facts

Photos like these are so helpful when a newbie is trying to figure it all out. I perhaps still can't totally visualize the mother mold, but I just haven't done enough work yet. The rubber that you have used must be a paint-on rubber. Is it an RTV silicone, or a latex rubber? It sort of looks like th...

I just want to clarify something for those who haven't used rigidizer yet. Regular duraboard doesn't stick to glass (well a few fibers come off with the glass, but brush off it). If you rigidize with the usual stuff (colloidal silica, and Hotline rigidizer and probably most others), then it will sti...

You can just put chunks of board under your ring to raise it, or kiln posts. You don't need to worry about the glass creeping under the edge of the board if you leave it flat on the shelf cause you're not going to fire it high enough for it to really flow, are you? If you fire too hot, then the edge...

I tried making shards in the kiln with very limited success. I set up wires across some kiln furniture about 2" apart. It sort of worked but the temperature is so finicky. At one temperature, nothing seems to be happening, just a few degrees higher and it drops dramatically. If you're watching, you ...

The way you describe it doesn't sound possible. Very likely, the top shelf was a lot hotter than the rest - when you were peeking, you weren't looking at that shelf, were you? However, if both disks were the same glass, one shouldn't liquify while the other holds its shape. Is it possible that the t...

Someone please correct me if I'm wrong, but I thought that Back Magic and Bending Glaze shouldn't come in contact with anthing. I know they have to be fired with the glaze up, but can you then put them against a mold on a subsequent firing without problems?

I was also disappointed with the Armstrong. I ordered a sample set, and was expecting real colored through the sheet glass, not an enamel coating.

Looking forward to seeing the Youghigheny glass.

I've charged $15 for a 20x20 load. That is only enough money if I wasn't going to put something in it myself. At that price you could easily have no kiln time for yourself, on the other hand, it can help pay for a new, bigger or better kiln. Just make sure that you don't end up doing a bunch of extr...
