Hi Gang of Glass !
I just started glass fusing and I'm having a blast
I tried to make a wall pocket using the kaiser-lee fiber board between two bullseye 90 glass the top piece was fired with a design before, then I used the board with part of it sticking out above about a 1/2" and made a sandwich.
I fired the first at 1400 at speed 2 with a 15 min. hold (Fusion 7-Paragon)
The second at 1450 same speed with 10 min. hold
Here's my problem after 2 tests.... THEY Broke..... I'm really sad...First of all I couldn't get the board to come right out. I had to dig it out and I was very careful when removing the stuff I sat it down at my desk walked away for about a 1/2 hour and I heard the TINK sound of disaster. The second on I didn't even try to take the board out and it cracked along the sides of the slump line (at least it was only a crack)

Anyone know if I'm doing something wrong? Do you think the Kaiser Lee board is the wrong slummping material for this?
If you have any suggestions, I would love some helpful hints

it's an annealing problem. you need to ramp down at a specific rate, depending upon the maximum thickness of your piece.

if it's a 2 thickness piece of glass, a typical rate would be hold at 960 for 20 minutes, 100 degrees/hr to 850, 200/hr to 700, then turn off.

Hi Charlie

I have a totally digital Paragon Fusion 7 I have no idea how to do what you suggested....looks like I have some reading to do

Thank you so much for the idea...... Have you used the Fiberboard stuff before?

rtm. if it's digital it should do it somehow. also read the tutorial on this site about annealing. buy the book.

no, but i think this type of fusing with anything in there you'll have the same problem. almost anything flexible will get stuck in there and you'll have to dig it out.

I agree with Charlie, however you might want to hold at 950 for a little longer and ramp down slower, because the STUFF you are using to make the pocket acts like an insulator and keeps the bottom from loosing/gaining herat as fast as the top.

Also, Don't use fiber board. As you have found out, you can't get it out.
Instead, use fiber paper/blanket. You will still have to dig it out.

Have fun, I hope this helps.

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 and then go to 100dph when it hits about 1200.

Oh - yes, you will have to dig out the fiber. Design it so that it's wider on the top than the bottom, and use your handy-dandy coat hanger tool. You know, the one with one end bent at a 90 degree angle, and the other end bent at 45 degrees...IF you can find a wire coat hanger. Harder to do these days. I find myself hoarding them!! hahaa.

I have also discovered that if I sandwich the fiber paper with thinfire, that 'sometimes' (if I'm lucky, or the moon is just right, or something...) it will just slip out if I have designed it right...those are the happy moments!
Good luck!

You are so right!!!! It all depends on the moon. Is that why my mold cracked???

hmmmmm Alice De

Thanks gang of glass

You have given me hope that this will work

Now... I just need to read up on how to slow the cooling down !

Thanks a bunch

I'll post as soon as I get one done without the dreaded 'TINK' sound

Hi Twinkler 2,

making pockets with any fiber materials can end in a disaster if they are bigger than 1/2 ". Fiber boards or fiber paper are insulation materials and the glass under the fiber is colder, while the glass around the fiber is hot.

We take copper pipes, hammer them down a little bit, cover them 2 or three times with thin fire paper and sandwich it.

Good Luck

Alice what type of mold are you using? ceramic? If so, you need to ramp it slow or else it will crack over time.. I go at 300 DPH.

Can some one post a picture of a wall pocket?
I think I have seen some of these in some galleries. I tryed to do a small valentine one, it was only about 3 1/2" x 2 1/2". I just used one piece of glass on the bottom and one piece on the top with about 5 layers of fiber paper centered and sticking out the top. and sandwhiched it between the two pieces of glass. It did not break, but the top edge where the fiber paper was touching the glass was very jagged and I got a bubble in the middle at the bottom where the fiber paper ended.
But, I am a total newbie, I do not even know if this is what a wall pocket is.
Thanks

Cyndi,

You did see wall pockets in the gallery. Go to the gallery and click onto Lynn Bishop. She makes beautiful wall pockets.

Judy

Does anyone know where I can get some instuctions for making the wall pockets?
Cyndi

Cyndi,

You might search the old archives. I believe there was a long thread about wall pockets a couple of years ago.
