Re: How do I full fuse keeping the original shape...

Hi Havi,

Yes. To keep it the same size you will need to build a dam around it. Use kiln furniture around the square. Line the sides with 1/8" fiber paper. Make the fiber paper slightly shorter the thickness of the glass to produce a rounded edge.
Happy new year.

Re: Can I slump directly on a kiln shelf without a mold?

No reason to not do it. Be sure there is some folded fiber blanket under the raised parts so that the blanket doesn't flatten out during the slump. Calculate your annealing time for the piece in the mold because it will cool slower than the piece over the fiber blanket.

Re: Gasoline-Powereed Sandblasting Compressor Comparisons

Hi,
You can get a 60 gal. compressor at Home Depot for about $500. It doesn't seem that it should cost $500 to bury a 50 ft. electrical line. Depending on usage even preserved gas goes bad and has to be disposed of.

BillsBayou, It is just as you see it on the Delphi page. It is called Baroque Glass made by Spectrum. It comes in many colorations. Most are either clear or white with another color, sometimes all three. I don't know if they will continue to make it when the line is moved to thee Mexican plant of th...

Re: cracked in half

Daryl,
I misunderstood your answer. I thought you meant the base was 2 layers (one transp. and one opal.) I would suggest that you pre full fuse 2 layers for the base and then add your design.

Re: cracked in half

Daryl,
In that case, I would go for the 3 hr. anneal hold as that is a change from 2 to 4 layers adjacent.

Re: cracked in half

Daryl, That is a very pretty piece, but a very complex one from a thickness variation standpoint. That will require extended annealing. How many thickness of base glass and was it fired separately to a full fuse? I don't understand the purpose of the many holds on the way up. I would suggest the fol...

Re: Help - troubleshoot cracked glass

Hi kdd, Beautiful panels. Your schedule is very conservative and should be fine. At most, you may want to drop your anneal drop temp. to 80 or 90f/hr. I would examine the mounting frame with a steel straight edge to look for a high spot near the middle. If there is, and the glass is pressed tight on...

I suggest sending an e-mail to governor Brown of Oregon with your concerns on this subject. Just Google "governor Brown, Oregon" to get her web page where you can send a message.

Re: Removing Rim From A Large Drop

Hi Buttercup, If I wanted an octagon, I would start with a square. It is easy to cut the straight lines with a tile saw and the sawn edge is clean and easy to polish. The reason I went with a 19" square over a 12" hole originally was to minimize the chance of the glass falling through the ...

Re: Removing Rim From A Large Drop

Buttercup, In the future I would probably start with a circle to save glass. Seachange's photos show the Bullseye method which will leave the sawed edge facing upward which is easier to finish with the "wet grit on window glass" method. If you tried with the flange down you could only cut ...

Re: Removing Rim From A Large Drop

Thanks Jen, The drop started with a 19" square blank, so it had a square rim. With that large rim it was too high to hold it on its side and run the blade parallel to the rim for a cut off (Bullseye method.) So, I first cut off the 4 corners on a 45 deg. angle with a 2" rim left as that wa...

Re: Removing Rim From A Large Drop

Thanks all for the good ideas. The sandblasting sounds interesting and safe, although 5/8" might be a lot to cut through. Here are some photos of the drop.

Re: Removing Rim From A Large Drop

Hi Seachange, What is a railsaw? The 2 reasons I went with the drop out were the shiny both sides that you mentioned and the overall size. The 12 hole with an 8" drop produced a much larger vessel. Also, in my one trial with the 3 molds the final slump was not a uniform height. Apparently, one ...

Removing Rim From A Large Drop

I have started making large vessels using 24" sq. kiln shelf into which I have cut a 12" hole (monster job with carbide jig saw blade.) The vessels are 8" deep by 12" diameter plus the flange at the top. The glass started as a 19" sq. by 5/8" thick. This one I finished ...

Re: Annealing question

It would take just as long to get even at 1000 as 900. Then you have to add time to get it down evenly to 900 slow enough to keep it uniform. It doesn't matter how hot it once got. All of the stress is avoided starting at an EVEN 900 and going very slowly (80-100 f/hr., depending on thickness) to 75...

Re: Annealing question

Yea... But can you actually release stress at the low temperatures of slumping? Chris, Slumping temps are high enough (over 900f) to require a correct annealing. The annealing hold at 900 f serves no other purpose other than getting a uniform temp from top to bottom and side to side of the piece. T...
