I think you are refering to "Powder Wafer Design Elements" by Paul Tarlow. He used to be an active member of this forum & now has his own website "fusedglassbooks.com".

Would they fall over or loose their shape if the powder frit was mixed with CMC?

You should check if both controllers are using the same temperture scale *C or *F, then check controller to see if it is working & going thru a complete schedule, if it is testing is in order.

I am interested too

Thank you very much for the info!

I am finally getting back to fusing after a long break.
Is there anything I need to check before I test my kiln ( Glass Glow) after not using it for 10 years? It's got a nice Paragon controller that I don't want to mess up!

It should as long as it will fire to the processing temps you need for your work. The Skutt ones I looked at had a top temp of 1700*, which is higher than you need for Bullseye glass.

Havi, have you tried turning it off & unplugging it for an hour and then replug it in & setting the new program? If this doesn't work check circuit breaker or fuses.

I use a cordless Dremel with a diamond bit from Harbor Freight, in a shallow pan of water. Cordless will keep her from getting shocked - water on bit and glass will keep it from heat shock.

How did your "Ball of light" turn out?

No it's not that unusual when using glass from different manufacturers, even though they are supposed to be the same COE. There are other factors that determine compatibility, that could be explained better by others. Even some glass made by the same company with the same COE can show incompatibilit...

What is the thickness of each layer you are fusing? They look like single layers so maybe your annealing segment is too long. I don't think you need to add the thickness of your fiber paper, just the glass.
The cracks look unhealed, if this is correct then it cracked on the cooling segment.

You might want to check BE reactions, straight advice I got years ago from BE Reactive Potential of Bullseye Glass (charts) When certain Bullseye glasses are combined in the kiln, their chemistries may react with each other to produce special effects. The reactions will take place at the interface (...

I would think you would need stone with the same or very near the same COE as the glass to keep from fracturing.

If you need a larger hole you could use "refractory fiber rope" that has been soaked with kiln wash & completely dried to facilitate removal.

WOW! What if every company treated their customers that way?

Sure you can make pattern bars out of them, BUT FIRST sandblast off the devit.

I've got a revolution also, very expensive but it works great. Yes it can cut a circle and compound curves (easily cuts 1/8" wide pattern bar slices) and for more intricuit cuts there is a blade available with diamond on both sides (blades are round and hollow, no center).

I use it for sandblasting. If you are going deep you just brush it on thicker, it adheres to the glass wonderfully and pulls off clean.

I use Spraylat, it is great for touching up etchings (remasking areas where the origional mask didn't hold and for texturing) and masking 3D and uneven or bumpy surfaces. Because you paint it on it works great with stencils and for different effects. A little bit goes a long way. I got 2 quarts 15 y...
