  •   Core Drill Bit
By on
Pros : This is fast and clean. Works great in a drill press. Saves so much time and is cleaner and more accurate than trying to drill holes with a grinder bit. How did I do without it till now?!
Cons : None

  •   The best I've found
By on
Pros : I've used this bit for a couple years now. I have great success with them. They seem to last much longer than any others I've tried. There are more expensive bits out there but I don't believe they perform any better than this one
Cons : None

  •   1/4" Core Drill Bit
By on
Pros : Quick cutting bit for glass. You dont have to file the hole smooth when done.
Cons : Make sure its to size. Did not fit my dremel. This size fits your regular drill.Ackward for jewelry.
Other Thoughts : Would be good to have a set that is small sized to fit most glass projects and that will fit the rotory tool.

No oneknowstheexactorigins of glass fusing although there is evidence that the Egyptians were familiar withrudimentary techniques. The Romans however arenoted by scholars for developingrefined glass fusing skills. Although technology has changed the way modern glass fuserswork,the technique isessentially the same as those developed by the Romans centuries ago. The basic technique involvesstacking two or morelayers of fusible glass, which are then placed in a kiln and gradually heated to between 1450-1500 Fahrenheit.At these temperatures the layers of glass fuse, or melt together and become one. Unfortunately, glass kilnsare large andexpensive,whichkeeps most Hobbyists from pursuing this art form. Now there are new kiln options, including theThe Fuseworks Microwave Kiln. This device works in most household microwaves and can fuse glass in about 3 minutes. Here are some common questions we get on fusing in this modern-day kiln. The following are Q A complied by Diamond Tech, the manufacturer of Fuseworks

Can you please tell me the correct way to mitre the lead for diamonds? Diamonds can be tricky. This diagram shows the way we would go about cutting the lead for a diamond. We find the easiest way to decide where to mitre the lead is by drawing lines on the diamond connecting the opposite points. Then, put a piece of lead on the glass and extend that line onto the lead. Now remove the lead and cut it where you marked. Replace it on the glass, lining it up where it belongs and mark the other end of that piece of lead. Cut it, replace it, and continue until all of the pieces of lead are cut. Reprinted with permission from Stained Glass News. All rights reserved.
