I've got a few of the Dragon brand molds and think the quality is good. I also have a few Slumpy's molds and think the quality is rather poor. The Bullseye 4.625 mold is so close to the size of your blank that I'd suggest testing one since their quality is great. I'd think a bowl that sits nice and...

I have that mold from Slumpys. 5" is the measurement of the bottom of the mold. I believe the measurement from the top (the very tips of the corners) are 4 3/8". Would probably be the perfect size for your 4" pieces. I remember because I had some 4 7/8" blanks so I ordered the 5...

Buy a 5" http://www.slumpys.com/Warm-Glass-Molds/The-Jumpin-Splash-Collection Dana W. Many thanks Dana, In the picture the 5" slumpy mold seems to have higher corners, this is more likely to give me enough depth for the 4" blank. Will compare the measurements this evening. Best regar...

I use the same annealing schedule for 4" x 4" x 6mm or 40" x 80" x 6mm. Charlie is right 1" x 1" is easier to anneal. According to the formula I use for determining annealing schedules, my schedule is quite conservative. Thanks Bert, remembered from previous posts you ...

I anneal 6mm float glass like this: Hold at 1000ºF for 36 minutes 1000 > 900 take 36 minutes 900 > 700 take 24 minutes 700 > 300 take 24 minutes Hold at 540ºC for 36 minutes 540 > 480 take 36 minutes 480> 370 take 24 minutes 370 > 150 take 24 minutes Thanks Bert Would you consider this as very cons...

Without knowing the details of your pieces other than size and your currant firing schedule. I would think that the thermal mass of your kiln is slowing you down more than your annealing hold time. With only two layers of glass I would shut the kiln off when the pieces were done and let the kiln co...

I find at shows there are some (potential) customers who are afraid to even enter the booth space. I make sure every item I offer is priced so they can see it without asking, much for the same reason Marty mentioned. That way, if they can't afford my work, I don't have to do any song and dance arou...

I have some old tapes from Dragon Glass and here is what they recommend: Annealing schedule Size - from 30cm (12") to 45cm (18") Total thickness of glass 3mm (1/8") - 6mm (1/4") Fire down from 650C/1200F no faster than 150C/300F Glass Notes by Henry Halem says 1 hour at annealin...

Can you slump the square shape in a round mold? The Bullseye mold's description is 0.75" deep for the 3.5" x 3.5" slumper. This one is 5.7" in diameter and 0.9" deep. If my calculations are correct, that will fit a 4.03" x 4.03" square. http://www.dragonglassmolds...

Hi again, would you know a source for molds like this http://shop.bullseyeglass.com/square-slumper-b-3-5-in-89-mm-slumping-mold.html , but in 4"? These are an odd size, 3.50". The plates I am currently making are 4x4". Because of the stiffness of the float glass (2 layers), I am getti...

Hi, Could you please recommend the fastest (while still safe) annealing schedule for 2 layers of float (total thickness 1/4")? Pieces are smallish, 4" and 5" square plates I am very much behind with the work for the season, starting to panic, so trying to make 2 firings in one day, in...

have permanently marked my 'silver' shelves by filing a notch on one edge with a round file...but this is no help for writing on molds

best regards, seachange

Vow, I just arrived back home and found all your posts, many thanks! From your replies most shanks seem to work, I think I'll be ordering some metal ones, and some clear ones in case I try transparent buttons, and testing the glues with a few good pulls. lbailey, thanks for mentioning about the weig...

Hi, Have a request to supply glass buttons to a gift gallery. Could you please help me to choose the best shanks? There are metal, plastic, even glass shanks available. Also, i use E6000 successfully for all my jewellery. Large pendants with a small bail are the only ones that I clamp for 24 hours. ...

I would also recommend the Gryphon/Gryphete. It is a real workhorse. Mine is 9 years old, and I use it constantly. For jewelry production and for plates. To round off the corners of square pieces, to seam the edges, and to grind off any imperfections resulting from glass cutting. Also have an inland...

your first link reminds me of BE ball mold 008737. it has that nice rounded shape. it is only 20" though, so the final bowl will be a bit smaller. Still a very useful size for a lamp...mold is expensive, as Brock said.

cheers, seachange

Firing upside down will flatten the bubble and often changes the shape. It won't, of course, make it go away. You may or may not like the result, but it does at least get rid of the bulge and it won't reappear on the third firing. Alternatively, you could drill through the piece from the top to ope...

hi, have made a set of coasters as a gift (float glass, 2 x 1/8) but the inclusion has created a bubble, so the surface of the coasters is not flat. do not have time to do them again so thought to fuse them upside down ( bubble towards kiln shelf) to about 1400f/760c to flatten the bubble. then fuse...

Many thanks Jim

I had practically decided on B (due to good range in smaller sizes), happy to know they have a square bottom.

Best regards, seachange

Hi everyone, I have a project where I will need to buy several molds (6 of the smaller sizes, 3 or 4 of the larger ones). Bullseye catalogue 8, page 52 shows square slumper A ( http://shop.bullseyeglass.com/square-slumper-a-4-625-in-117-mm-slumping-mold.html ) and B ( http://shop.bullseyeglass.com/s...
