Re: Glass not filling void in lost wax technique
I am using a basic plaster/silica/water mix, all equal amounts by weight. Besides the soda lime glass I have also been casting float which, according to the schedule I have, needs to go to 1950 degrees. The molds cracked in that firing and I wonder if the higher heat is a factor and should I increa...

Re: Materials for casting a container
The lower density board will insulate the glass you are heating and make the firing slower and longer. The higher density board would allow more heat transmission through conduction of the kiln heat through the material and into the glass. The lower density board because it is less dense has infini...

Materials for casting a container
I cast some containers (1/2” thick) using vermiculite lined with 1/16” fiber paper. Plaster-silica form in the middle. It worked OK, but the fiber lining was a pain. I’d like to try: -Coating the vermiculite with plaster-zircopax mix (40-60). Charlie Holden (whose studio I inherited) had this in his...

Re: Using oxides as colorants
Thank you so much, Brad.
Having recently poked around on some of the Facebook groups for warm glass, I appreciate this forum even more than before (and that was already a lot).

Using oxides as colorants
In the studio I inherited from Charlie Holden, I found three bags of powder from the ceramic store: nickel oxide, chromium oxide, and copper carbonate. (The nickel oxide is black, the chromium is a gorgeous dark green, and the copper is a light green.) I know these can be used in ceramic glazing, an...

Annealing small thick pieces
I have always used BE “Annealing Thick Slabs” schedules for pieces of any size. The smallest thick pieces I’ve fired have been 6” by 8”. Another glass artist showed me a smaller piece that was a uniform 1-inch thick, about 4” by 4”, and said it didn’t need to follow the BE schedule for annealing bec...

Re: Glues and silicones
check out www. Panacol-USA , I have used a lot of their adhesives with great success. They even have some of my applications shown on their website. They make a lot of different adhesives depending upon your application. They used to be called Tangent Industries but were merged with a European comp...

Re: Glues and silicones
Thanks, Jennifer. I was only familiar with Hxtal as advertised on the Hang Your Glass page - this is a much better explanation. Had not tried it because it’s so expensive, but this information convinces me it’s worth a shot.

Group use of a large studio
I have “inherited” a well-equipped 2,000 sq foot glass studio in Decatur, GA. It’s a bit complicated (explained below), but, I’m wondering if anyone has experience with running a studio for group use - a guild, a collective, a membership structure? In the short time that I’ve offered it for open stu...

Glues and silicones
Interested in recommendations regarding glues and silicones for the following use cases: 1-Assemblage of small, clear glass pieces (e.g. a sculpture composed of different kinds of glasses that aren’t compatible for fusing). I have used Loctite glass glue. It dries clear, stays clear, is fairly stron...

Re: Fusing antique glass
Just for your future knowledge... If you tried to fuse single thickness glass by butting edges together... they will actually pull away form each other at fusing temps... leaving gaps (holes) in the final piece. Thanks. I was wondering about that! Kevin suggested using some kind of flux to make the...

Re: Fusing antique glass
Thank you Kevin. Your list seems to cover all the bases. I don’t know what I would use for flux - would appreciate ideas on that. Have never worked with antique glass so I don’t even know how to research such a thing. Or what the fusing temperature might be. I’ve only played around with Bondix UV gl...

Fusing antique glass
An acquaintance has an antique cabinet from England that has broken gravity glass in one of the two panels. He wants to know if we can fuse the broken pieces together. The break was fairly clean but there are a lot of pieces: 239ED37E-FD35-42E4-8D5E-BC5110427AB0.jpeg I haven’t seen the glass in pers...

Re: How much weight can wire inclusions bear?
I've had no problems with the series of heavy solid fused crushed glass masks I made in 1992 with copper wire embedded in the back for wall hanging. The best hanger was 12 gauge copper wire bent in a U and pushed deeply under the crush prior to melting. Your experience may vary. Interesting - good ...

Re: How much weight can wire inclusions bear?
Many of the wire and glass pieces made in the 1970's are now starting to crack. And I've seen fused wire pieces crack much more quickly than that when the wire is thicker. The COE for most metals is 150 or higher. Wow, that’s very good to know! Wish I could remember where I read about using wire in...

Re: How much weight can wire inclusions bear?
The exact weight breaks down this way:AndyT wrote:What size is the project? Average weight of glass is around 1.8lbs/sq.ft.
The background is about 12x18, two layers, so 5.4 lbs
The mask is 2.5 pounds
The strands are less than half a pound
I was rounding up to 10 pounds.

Re: How much weight can wire inclusions bear?
What gauge wire? What material wire? I would be more concerned about long term compatibility than holding up the two layers. High fire 18-gauge stainless steel wire (from Fused Glass Warehouse) I was not aware there’s a compatibility problem with wire inclusions... Or do you mean the glass? What do...

How much weight can wire inclusions bear?
I am planning to tack fuse a cast face and some strips of glass onto a background of two sheet layers. My original plan was to fuse wire inclusions between the two background layers at the top edge, to allow hanging. I want to keep the piece transparent so don’t want to use Hang Your Glass. But now ...
