We can make it for you. Email me

I put our round pattern bar formers on end like this in every full fuse. No special temps are needed. They shink in height around 25%. If you spray the 1/8" fiber paper with MR97 before loading it the glass will slide easier with no spikes!

I recently purchased some Ceramic Coating made by Primo Primer that is supposed to solve this problem. I then purchased a perfect new smooth shelf so I have this unopened. If you want to try it email me! To read more about it go to Ed Hoy and look under Primo Shelf coating I think.

This is exactly why we make our mold " Bottomless"!!

Cynthia......about the MR97 on fiber.......if someone has a small studio and only a small grinder.....and is doing let's say scrap melts ....the MR97 on the fiber paper makes a huge difference. I have done side by side tests on my birdbaths that are piles of scrap glass getting melted.......can't al...

agreed…..my mind was on scrap as that is what I was using today!!

3 layers is probably over kill. I also spray the inside of the 1/8th inch with mr97 so that I get no spikes that need grinding off. My other suggestion would be.....if you cap it in clear you arenprobably going to have quite a few bubbles. I would consider doing it in 2 steps....cap in second firing...

I fire 9999 to anneal all the time and I never have issues…..I think it depends on your kiln and how fast it cools. mine is very insulated and cools slowly.

I would not hold more at 1350 than you have to…..

hold at 300 does nothing
I personally would not hold at 1350 because it is in the devit range…..but I guess it worked for you last time?
is the base glass already fused as I see no bubble squeeze?

As I said....i have not used it on a shelf yet......but Warren Norguaard (who is the glass artist who started the face book page Fused Glass Fanatics) has said that he does use it on shelves and really likes the finish it leaves on the back of the glass. On a new shelf he gives it a double spray.......

On casting molds I brush it off with a stiff brush and just lightly spray again. We are distributors for MR97 and I am still learning new ways to use it. One great way I have discovered recently is that if you spray mr97 on your 1/8" fiber paper that you line stainless steel rings with ....you ...

Please do not let one sad angry pitiful jealous person spoil this for you. there are oh so many more that are inspired by you and you generosity. Hopefully Brad has banned that person from the entire board.

I use a triple balance beam scale from my pottery glaze mixing days.

Way too fast. Personally I would anneal for 2 hours then 50/hr to 800, hold 60 and off. Such a fun piece too! I would refuse it although to heal the cracks you will lose the wonderful effect you got from the tac fuse.

As a potter I made fused glass wind chimes on pottery bells for years. What we did was to make a u shape of nichrome wire and fuse it between 2 pieces of glass. 25 years later I have customers tell me they still have theirs.

Layers with powders......prefire each layer flat
then fuse together

It would be interesting to see a pic of the entire mold.

Any piece over 12" i add that extra step to 750.

If you want absolutely no bubbles in a piece prefire your base with out the edge design. It will weight it down just enough to trap some air. It does take an extra firing but can be worth it. I can fire a 24" round of 96 with the schedule Dana suggested......going 50 degrees an hour from 1100 t...
