Trying to understand more how glass behaves I have noticed that _very_ old bottles and glasses have a grayish matte surface. I suppose that they were made clear. 1. Is the matte due to devit - that is does glass devit slowly in room temperature? From my limited understanding of glass chemistry, I t...

I have not tried doing both at the same time, but do not believe it would be successful. Even though the maturation range of Super Spray is stated as being 1300 to 1700, I have never heard a report of Super Spray maturing at a temperature in the lower part of the range. I take the glass back to fusi...

snip... My kiln is my laundry room and I would love to skip the flash venting....I guess too, a matter of time, my kiln loses heat pretty slowly and I imagine not flash venting would add hours to every fire. lissa. My brick kilns take less than a hour to drop from fusing temperature to 990. (If I m...

Glad the fuse worked, and hope the slump goes well. Jerry

Marilyn, I assume the bubbles are occurring between the glass and the shelf. There are a number of possible causes, but those bubbles can be eliminated by firing on fiber paper. However, I would continue to fire the pendants directly on the kiln-washed shelf as their back side will be smoother. I as...

I love the word crafters when used with a show. It allows me to be sure that I don't want to do that show.

I look for a piece where I feel any change made in it would diminish the piece.

Hey Jerry, Does the building you are thinking of look like an upside down step pyramid? I'm trying to think of the building you are talking about and can't remember. I drive down there all the time but haven't paid close enough attention. I'll look next time it's less than 5 min. from my house. Amy...

There is a building in downtown Milwaukee (Water Street?) that is Corten. The first floor is recessed to provide shelter so there was an orange drip line on the sidewalk. They may have etched it off the concrete after the steel had aged. Corten is primarily a structural steel and may not be availabl...

He was probably more reasonable because he had a woman's intelligence guiding him behind the scenes, and you were probably coming from a less fearful place because you had some muscle behind you ! And they say the sexes can't work together - ha! Glad it worked out so well for you. Dani, have you fo...

The link at the top of the page to Tutorials will get you started in understanding what can be done in a kiln to shape glass and how. Beyond that, there are books on the subject. If it still looks feasible, find someone with experience in kiln work to help you. Any glass of any thickness can be bent...

Do you think it had anything to do with the fact that where there wasn't design the plate was only 1/8 in thick? Absolutely. Should I next time make the base 2 layers of glass? That will help, and use their schedule for 3/8" thick. The alternative is to ramp at no faster than 120 to 1000 for t...

Thermal stress arising from temperature differences in the glass as it cools from its strain point to room temperature, in combination with residual annealing and compatibility stress, can be enough to break the glass. The hotter the kiln is when opened, the easier it is to have sufficient temperatu...

I have not had the success with the chad method that others report. This may just be me, or heightened expectations, or some variable in our firing schedules. If you use frit, as it melts into the surface the individual pieces of frit will displace the underlying blue glass leaving a visual texture ...

I didn't see my favorite; Boar's Head White Wine Mustard jar. I also love those little pimento jars.

G'pa Jim

Jim, did you manage to snag a collection of baby food jars too? Or do they not have screw off caps any more?

but the glass edge took on the shape of the blanket as it folded in order to curve around the edge. Do all of you Lords of the Ring line them with fiber paper or have you been able to get the glass out of a large ring with only kiln wash on the ring? To have a smooth edge, do you then cold work the...

I have received several requests to return to the old board format. Please take a moment to register your vote on this topic. Thanks. Does return to the old board format mean: Keeping this site but having only a main forum and a classified forum to match the format of the old board? Or are you thin...

Michelle, I think Phil is right that grinding the edge increases the probability of getting devit with any glass, but with red opal this will occur with as-cut edges as well. Seems to be the nature of the beast and, from its position, related to the interior of the red opal glass ending on the surfa...

Given the fairly large quantity of newcomer posts we've been having lately, it certainly makes sense to have a newcomer board. That seems straightforward, but I'm not sure how other boards would work (or how to segment things). Anybody have any suggestions? The current forum segregation is by subje...
