same way you test which side has the dichroic on. put your fingernail to one surface. if the coating touches your fingernail that's the surface. if there's a gap the thickness of the glass, then it's the other side.

I've never tried this , however, I have READ that you could use an inexpensive coffee grinder for small scale frit making. Anyone else ever heard of that? :?: yes, for a few times. it wears out really quickly. you then have to clean it well and put it back in the kitchen for your spouse to find, an...

So what do I do about it? I only run the venting system during the initial heating through the brittle zone ( I turn it off at about 800F). I don't use it for cool down. I run the vent through a dimmer switch to slow the fan speed down. you probably already know this, but a lot of motors aren't des...

1/2" plywood. 4" wide piece ripped at 45 degree angle down the middle.

Well, I am looking for a continuous border with no seams and stacking is the only way I know to get it. I guess Ihave been really lucky, because I have done it successfully probably 15 times before the explosion. I have slowed my schedule down to 200dph ramping up and hope that that solves future p...

The moral for me....is know your kiln, and consider when the problem started and what preceeded that. Thanks for all your input. I am much smarter as a result. Carla working at a computer manufacturer doing customer service, the first question i ALWAYS ask is: if it used to work, what did you change?

Both of the pieces I'm referring to were thick float glass. They both made that "ping" breaking noise from thermal shock, one when subjected to uneven heat (a commercially made, thick float glass table top), the other when subjected to rapid cooling while it was still very hot (probably 2...

Any ideas?

Thanks,

wet it. freeze it. drill it.

if i don't have to, i let it sit until room temp. if i have to, i open the kiln at 200, and take it out and wrap it in towels at 150.

of course, in the summer, room temp is 115-120.

do a search in the old archives as there's been lots on this in the past.

cutting thick glass can be done with an ordinary cutter, however it's easier with a different cutting wheel. the thicker the glass the wider the wheel angle.

Just bought some foils from BE, so your posts are very timely. Would you explain how the oil is used? I had planned to use glue. And why is oil better than glue? Hope you all are not getting tired of all my questions. :oops: New comer Kay to hold it down? if you're putting it on top, you want it to...

ok, it has rained for a week. it will rain for 3 more days. i am out of indoor 'real' work. so......i NEED to buy a compressor. i can spend up to 200$. home depot is where i will shop. that said, will some of you compressor/tool gurus help me? there are too many choices. i mostly want to run my air...

Make sure one of the two holes on the side of the airbrush is plugged. You'll find the plug with extras in the kit. Will it spray water? If not, rotate the wheel on the back top side of the airbrush until it does. If it does spray water, then try a different tip. The turquoise tip works the best wi...

I have an aztec air brush and I can't seem to get it to work. It is clean. I am getting air but it won't pick up the mica from the container. Any suggestions would be appreciated. I have tried varying the mix and using different tips and different containers. what are you using for your medium, and...

Chuck, What did you use to put the micas on? Were you silk screening them. If so what do you use as a mixing medium with the micas on the screen. Thanks Michael My e-mail : artglass101@hotmail.com The one on my profile is a dummy that Brad set up for me. most probably with an airbrush. medium is kl...

elmers glue is water soluable.

What does the glass bowl sit on ?? What about sitting it on a double glass shelf of say 1/4 glass spaced out slightly And sandblasting the under side of the shelves slightly This should help in ur evenivity the glass vase sits directly on the platter, absorbing the heat directly. since they're both...

Or you could put the vase up on little acrylic feet so it sits off the glass a little. The way you describe what you think is going on seems a little mixed up. I think you're right that the vase is acting as a heat sink and that the smaller vessel allowed more cooling. The key is even cooling versu...

Try light emitting diodes. No energy cost and last 100,000 hours. Look for a regular screw in one used for fire exit lights. The screw in bases come in small and regular bulb size. You should be able to find them at a lighting/electrical wholesaler.Kevin that's a good idea, but is it short enough, ...

can you get neon in regular bulb bases? a par30 is a very short lightbulb in the first place, and i don't really want to rewire the socket. also, i don't believe neon is dimmable either.
