Re: Best kiln
Coffins are also called "bathtubs," so if you hear that term, that's what it means. For fusing, i.e., sticking sheet glass or frit into the kiln, firing it until it flows together or slumps into a mold/form, and cooling it, any kiln that will keep the elements at least a couple inches away...

Re: Inconsistent Reaction Results: French Vanilla and Dense White
Reactions will intensify and eventually even out...to a point. Usually that's the point at which the reaction potential has been exhausted, or the crystal growth has maxed out, or the glass has just basically used up whatever it is that's causing the reaction in the first place. So your choice--if y...

Re: Freemont Glass
As has been mentioned here, there's more to it than just COE, or even just compatibility. Compatibility you can test for--if you're curious, I think Brad's book talks about how to test for compatibility, or any of Boyce Lundstrom's books will. You can also just google it--it's not difficult or expen...

Re: Clear Shield Gel
First...the idea that patinas don't change over time is nonsense. Certainly the ones I own have changed,* as have paintings, pastel and graphite drawings, sterling, wood, and ceramic art...and even glass. Art evolves, that's part of its purpose. And Marty's right: Wherever did I equate Clear Shield ...

Re: Slumping large pieces in Paragon Pearl 56
As Val said, need schedule, and it wouldn't be a bad idea to either show a picture of the mold and the piece(s), or to at least describe the shape and the sizes/heights. Lots of possibilities here. Depending on the proximity of the glass to the elements as the glass starts to heat, there could be a ...

Re: relays for kilns
Had Skutt replace my original controller, too, went to the solid state on the GM1414 bathtub, didn't bother with the high limit. I ran mine almost constantly, doing everything from 1550F castings that lasted a couple of weeks or more to quickie flat fuses, for several years without a problem. I thin...

Thanks. First, are you putting the reeds (the raised lines) to the inside or the outside of the layup?

Re: bubbles
And posting a picture of your layup before fusing, and the result after, will also help. There are MANY reasons for bubbles, and a few different types of bubble formation as well. There are also many ways to do a "bubble squeeze," so simply using the terms isn't really going to help us fig...

Re: Hemp twine, cord as organic material for burnout?
I stand (very) corrected. Yes, petroleum products are hydrocarbons and therefore contain carbon and are therefore organic. Apparently I have overdone the hippie bit because I have forgotten my organic chemistry and have apparently started using the term "organics" to mean "anything th...

Re: Hemp twine, cord as organic material for burnout?
Plastic is not the same as hempen twine. For one thing, most plastics aren't organic--many twines are--and if the plastic moose is solid it'd be rather dense and take awhile to burn out (assuming there's enough oxygen around for that). I could see a nice, long, oily petroleum fire, about like burnin...

Re: Bullseye Rhubard Shift Tint
Bullseye Rhubarb is the color I love to love and hate and crave. It may be my all-time favorite most annoying color. ;-) Seriously...it goes with everything and nothing, just depends on the form factor of the glass (powder or billet), what glasses you're using with it, and how you light it. It may b...

Re: Adding kilnwash to plaster/silica investment
#1 pottery plaster is almost always the easiest to find, and it's good, serviceable stuff--it's the basic plaster used in much of today's glass casting, especially beginning classes, and you can get it from just about any ceramic supply place. You can also buy "stones," i.e., dental plaste...

Re: melting frit to make a single piece of glass
No is the easiest answer. Probably the most accurate is "it depends." If all the pieces of glass that you broke up to make the frit came from the same batch, i.e., they were all poured into sheets from the same melt, yes. If the pieces came from different batches but formulations and proce...

Re: grinding and other abrasions effect between 2 fused surfaces
Mostly you just keep the ground surface wet until you can scrub off the swarf completely. If it dries into the pits and crevices of the rough surface, it's a lot harder to get out, even if you rehydrate. Grinding crud left on the surface is what leaves the cloudy, scummy appearance--it can provide &...

Re: Can I use this kiln for glass?
I'm with Val; if you can use that kiln to control temperature precisely for any given period of time, you can fuse and slump and cast glass with it. There are some great online resources (this is one; head over to the Bullseye Glass website and subscribe to their video tutorials, too), and then star...

Re: grinding and other abrasions effect between 2 fused surfaces
That's a tough question to answer because it's going to depend on the heat the glass receives after it's been coldworked, and for how long. Obviously, if you nuke the heck out of the glass long enough, it'll turn into a puddle and you'll get a smooth, flat surface, and if you barely kiss the surface...

Re: Adding kilnwash to plaster/silica investment
For all the precision I use in the rest of my mold mix calculations, I gotta admit I get all loosey-goosey on that one. It's literally as many handsful as I feel it needs to look right. :oops: Typically, though, it's just enough to cover the top of the mound I'm sifting into the water, so probably a...
