Bert: So when Brock says to go to 1510 degrees, I shouldn't? I could take it to a lower temp and hold it longer...will it devit? (The piece is warped, not bubbled, by the way - about 1/2" tall in the center...) I am holding off the next firing until I feel like I have SOME understanding of what...

Bert - You said that you didn't like 3/16 float glass - too thin and it devits...so, when I unloaded the kiln this morning - (Yes, I admit, I didn't do it over the weekend, I was fighting the flu) the one 'good' piece was curved up in the center - not flat. Now, my kiln is FLAT. With the schedule th...

When I had it built, I had it set up for multi-zone and I do have a Bartlett RTZ controller, so I could have my kiln guy show me how to turn the side elements off unless I am slumping. This is a new kiln - only ten firings so far - exciting!

Thanx again for all the advice!

Well, MY kiln is bricks on the bottom and fiber above with elements on the top and the long sides. It's 48 x 72. I have been firing for years in an old ceramic kiln, so have had VERY conservative firing schedules so that the centers of the pieces got hot, too. Since I am not used to top firing, I fe...

So, a further question - is 'slow' 250 dph or less? What is 'slow' to you? I know what it is to me, but not anyone else....

smiles, and thanks,
annah

Ok, I'll reprogram and try it slower. I just didn't want that devit...easy enough to try again.

Thanks a bunch!!

I am working on a project using 3/16" float glass. I am kilncarving over a lot of fiber paper. Yesterday, looking through the posts, I found a firing schedule for float glass that I thought I'd try, since I didn't want to have that cloudy look that I have sometimes gotten - and I THINK it's fro...

Hmmm...You've all given me lots to think about. The project is a "green" building, so all the products used in it need to be environmentally safe. I guess that shellac, being a 'natural' product would count...plus, I really don't want to add a color to the back of the pieces. Has anyone tr...

I have a client that is interested in tiles made from recycled float glass, which I can do; however, in the past I have been less than satisfied with installing tiles that are transparent since the mortar has to be done perfectly and then has to dry without cracking (a virtual impossibility...). I h...

I've made LOTS of wall pockets - I use 2-3 layers of 1/8" fiber paper. The more you use, the slower you have to raise and lower the temp. I have found that the worst breaks happen on the way down, so I take it at 50 dph. I know, it's slooow. but they don't break. On the way up, I start at 75dph...

I don't drill them, I have a guy sandblast the holes for me. That way, he can make the countersink for the hardware as well. I thought about doing the drilling thing, and it just stressed me too much. A good friend, though, bought a drill press and does the dam-thing with clay. He puts a sandbag und...

Nope, there's no natural light where this is going. I've never heard of the problem with COE's being different, though. I spoke to HisGlassworks folks about a potential project of glueing fused glass to plate glass on both sides of a stair rail, and they made it sound like the only product that coul...

I use a decent quality digital postal scale. Makes taring the weight of the container really easy. Now that I'm three days into this project, I am getting more used to the HXTAL. I am applying fused glass tiles (8x8) to plate glass panels. The fused glass is not *totally* flat, so I am using a lot o...

So of course, I wrote my reply and hadn't yet looked at your website. Duh!

Neat work!

I have been doing architectural glass for a couple of years now - tile murals, cabinet doors, windows, large panels for commercial spaces...I'd really like to get into some lighting! Currently I am working on an installation for the U of O - a lot of tiles glued to plate glass panels and backlit. I ...

Oh, I forgot one other thing - the folks at HisGlassworks said that the weight / mix was not 'critical'. I have a scale, so I could measure it, but there's no reason you couldn't measure by volume. Especially if you 're just mixing up a small batch. It might be harder with more.

I'm right in the middle of a project using the HXTAL. First time. It is a little bit of a challenge to use, and if you want it to be thicker, mix up a little bit and let it sit (covered) for a while. I used most of what I had mixed yesterday, and the directions said to freeze it overnight. When it t...

I have been embedding leaves in glass for years, and this is how I do it: There are two different ways I embed leaves in the glass, and it depends on the desired finished texture. Typically I am using Bullseye transparent irid glass as the base piece. If I want the metallic look of the irid to show,...

Bert: Thanks for your input! I have the room to lay these panels out for the time it takes to cure. My understanding is that the HXTAL is not a UV cure. It just takes time. My project will not be viewed from the back - it will be back-lit, so clarity is of the utmost importance. That's why the HXTAL...

Do you have contact info for the zircon and bohle folks? What about HXTAL? Have you used it? I am just getting ready to try it on a job where I have 16" wide x 59" tall plate glass panels 1/2" thick, that then have 8" tiles laminated to them. THey are stationary. What do you thin...
